Coriandrum sativum L. is a widely cultivated aromatic herb exhibiting substantial variation in essential oil quality and yield among different accessions. This study assessed germination performance, essential oil composition, yield, chemotype distribution, and fragrance characteristics in 48 C. sativum accessions collected from 19 countries spanning four Köppen–Geiger climate zones: Tropical/Subtropical, Arid/Semi-arid, Temperate, and Continental/Cold. All accessions were grown under standardized field conditions, and essential oils were extracted from aerial parts using steam distillation followed by direct-GC/MS analysis. Seed germination rates were consistently high (mean: 92.25 ± 5.85%; range: 71–100%) and did not differ significantly by climate zone (Kruskal–Wallis H = 5.500, p = 0.139) or country of origin (H = 21.833, p = 0.240), indicating that post-harvest management, rather than climatic provenance, primarily determines seed viability. Essential oil profiles were dominated by (E)-2-decenal (mean: 44.56%), decanal (11.75%), and 2-dodecenal (13.47%). Principal component analysis (PCA) of 18 compounds detected in at least 19 accessions accounted for 70.16% of total variance across five components, with PC1 reflecting a gradient from long-chain saturated aldehyde accumulation to linalool enrichment. Permutational multivariate analysis of variance (PERMANOVA) demonstrated significant compositional differentiation among climate zones (Pseudo-F = 1.662, p = 0.028), whereas country-level grouping was not significant (p = 0.256). Tropical/subtropical accessions exhibited the highest linalool content (mean: 15.39 ± 8.71%) and essential oil yield (mean: 0.269 ± 0.120% v/w), significantly surpassing arid/semi-arid and temperate zones (p < 0.05). Two chemotypes were identified, (E)-2-decenal (91.7%) and linalool (8.3%), each associated with distinct fragrance profiles (earthy/aldehydic/woody versus herbal/sweet, respectively). These findings demonstrate that climate zone of origin is significantly associated with C. sativum essential oil composition and productivity, with tropical/subtropical accessions providing superior yield and linalool content. Chemotype characterization offers an additional criterion for germplasm selection in targeted industrial applications. Full article

Bagrada hilaris (Burmeister) (Hemiptera: Pentatomidae) is an invasive pest that causes significant damage to Brassica crops worldwide. This study evaluated behavioral and toxicological responses of adults B. hilaris to plant volatiles and essential oils (EOs). Y-tube olfactometer assays revealed sex-specific responses to plant-emitted volatiles: females were repelled by Coriandrum sativum and Petroselinum crispum, while males responded to Pelargonium hortorum. Essential oils exhibited non-linear concentration-dependent effects, with C. sativum EO inducing repellency at 40–80 µg/µL and P. hortorum at 160–320 µg/µL. In contrast, repellency index was not influenced by sex, but strongly driven by concentration, with C. sativum and P. hortorum most effective, and P. crispum showing weaker yet consistent responses. Toxicity assays demonstrated greater male susceptibility, with lower LC₅₀ and LC₉₀ values for C. sativum and P. hortorum. Gas chromatography-mass spectrometry (GC-MS) analysis of EOs matrix identified linalool, β-citronellol, trans-geraniol, and myristicin as the predominant constituents. Importantly, repellency occurred at lower concentrations than mortality thresholds, indicating distinct behavioral and physiological mechanisms. These findings support integrating C. sativum and P. hortorum essential oils into sustainable pest management strategies for B. hilaris. Full article

This study evaluated protein hydrolysates from fish collagen (Col) and sheep keratin (Ker) as potential biostimulants in the hydro-priming of coriander (Coriandrum sativum L.) seeds. Seeds treated with low, non-nutritional doses of Col (0.5%) and Ker (1%) were compared with non-primed (C) and water-primed (H) controls under optimal conditions and after high-temperature stress (35 °C, 9 days). After stress removal, H-Col and H-Ker seeds achieved ~90% germination, whereas H and C reached 78% and 60%, respectively, confirming improved seed quality and post-stress recovery. Seedlings from Col- and Ker-treated seeds showed enhanced growth, higher biomass, and increased chlorophyll and precursor content. High-temperature stress also acted as a priming factor, modifying elemental profiles and stimulating carotenoid antioxidant synthesis. ATR–FTIR analyses indicated changes in cell wall composition and protein structure, particularly in the H-Ker variant. The results demonstrate that collagen and keratin hydrolysates, as industrial by-products, possess strong phytobiostimulatory potential and can be applied in sustainable strategies to improve seed quality and plant stress resilience.

Several honeybee species can coexist within a given geographical region; however, their interactions and the extent to which their foraging niches overlap remain poorly understood. To address this gap, we assessed niche overlap among four honeybee species (Apis cerana, Apis dorsata, Apis florea and Apis mellifera) in West Bengal, India, using palynological analysis of corbicular pollen loads. The monofloral composition of individual corbicular loads indicated flower constancy in all species. A wide range of pollen types was recorded for each species, confirming their polylectic foraging behaviour. Although the level of pollen diversity in their diet did not differ among species, it did vary seasonally. Vital pollen sources (including Acacia auriculiformis, Borassus flabellifer, Brassica juncea, Bridelia retusa, Cocos nucifera, Coriandrum sativum, Eucalyptus tereticornis, Lannea coromandelica and Sesamum indicum) were shared by all four species, and their pollen-foraging niches showed significant overlap in every season. Considering the floral traits of the plants visited, all honeybee species behaved as generalist flower visitors. This study quantifies foraging niche overlap among honeybee species and identifies common floral resources shared by the exotic Apis mellifera and native honeybees. Such insights will assist in honeybee management, biodiversity conservation, and the enhancement of ecosystem services and stability. Full article

Although herbs can contain several secondary metabolites potentially harmful to insects, dried herbs, like all stored foods, can be damaged by various insect pests. These pests have the potential to diminish both the quantity and the quality of food, and the consequences of infestation often only become noticeable once the pest has already become established. This study investigates the ability of two Lepidoptera pests, one polyphagous, Plodia interpunctella, and one selective, Idaea inquinata, to complete the postembryonic development on eleven dried herbs commonly used in cooking: dill (Anethum graveolens L.), basil (Ocimum basilicum L.), chervil (Anthriscus cerefolium (L.) Hoffm.), coriander (Coriandrum sativum L.), tarragon (Artemisia dracunculus L.), chives (Allium schoenoprasum L.), oregano (Origanum vulgare L.), parsley (Petroselinum crispum (Mill.) Fuss), sage (Salvia officinalis L.), savory (Satureja hortensis L.), and thyme (Thymus vulgaris L.). The results show that tarragon, sage, savory, oregano and thyme did not allow growth of either species, suggesting the presence of chemical compounds that limit larval growth or survival. In addition, the time required for both species to complete development was longer than that obtained on a standard diet, suggesting that the nutritional requirements and water content of the herbs are not as optimal as those of the standard diet. To conclude, I. inquinata could develop on basil, chervil, chives, coriander, dill, and parsley, while P. interpunctella could develop only on chervil, chives, coriander, and dill. Full article

Local vegetables and spices are essential components of traditional food and health systems in northeastern Thailand, yet quantitative ethnobotanical evidence remains limited. This study documents the diversity, utilization, and cultural significance of vegetables and spices used in Sang Kho Sub-district, Phu Phan District, Sakon Nakhon Province. Ethnobotanical data were collected in 2025 through field surveys, voucher-based plant identification, semi-structured interviews, and participant observation involving 92 informants across 23 villages. Cultural significance and medicinal knowledge were evaluated using the Cultural Importance Index (CI), Informant Consensus Factor (FIC), and Fidelity Level (FL). A total of 113 taxa belonging to 94 genera and 49 plant families were recorded. Poaceae and Zingiberaceae were the most species-rich families. Native species slightly predominated (51.33%), and herbaceous taxa were most common. Leaves were the most frequently used plant part. Most taxa were used as vegetables (92 species), followed by traditional medicines (20 species), spices or seasonings (18 species), and food ingredients or culinary additives (18 species). The highest CI values were recorded for Allium ascalonicum L. (1.152), Capsicum annuum L. (1.098), and Coriandrum sativum L. (1.043). FIC values ranged from 0.60 to 1.00, with complete consensus for circulatory and neurological disorders. Cymbopogon citratus showed the highest FL (75%) for gastrointestinal uses. These findings demonstrate the close integration of food and medicine in local plant-use systems and provide baseline data for food system resilience and cultural knowledge conservation.

Skin is constantly exposed to UV radiation. While topical sunscreens are the main preventative measure, oral photoprotective agents are emerging as promising systemic adjuncts, offering uniform, continuous protection. This study presents the results of two clinical trials designed to evaluate the efficacy of supplementation with a standardized coriander (Coriandrum sativum L.) seed oil (CSO) in mitigating UV-induced skin damage, in comparison with a placebo. The first trial investigated the effects of CSO supplementation on women with reactive skin, assessing UVA+B-induced skin erythema and tumor necrosis factor-alpha (TNF-α) release. The second trial included women of all skin types and, in addition to the outcomes mentioned above, examined UVA-induced lipoperoxidation. Measurements were taken before and after 56 days of supplementation. CSO supplementation led to a significant reduction in UV-induced skin erythema and associated TNF-α levels in both cohorts, with decreases of 11.8% and 24.1% in the reactive skin group and 18.1% and 18.7% in the cohort with all skin types, respectively. In women of all skin types, UV-induced skin lipoperoxidation was reduced by 31.9% at 4 h and by 69.9% at 24 h post-exposure. To the best of our knowledge, this is the first study reporting the photoprotective efficacy of CSO. This finding is attributed to CSO’s high petroselinic acid content and its known anti-inflammatory properties. Full article

Coriandrum sativum L. (coriander) seeds have long been used as a traditional medicine and a spice worldwide. Despite its abundant use, bioactive properties of coriander seeds, correlated with the antioxidant and phenolic data, have not been fully studied systematically. This study evaluated the phenolic data, antioxidant capacity, and antibacterial activity of coriander seed extracts obtained using solvents of differing polarity. Higher total phenolic content (TPC) and antioxidant activity were observed in the polar extracts, while moderate and non-polar extracts possessed higher antibacterial activity. Acetone extract (Ace) had the highest antibacterial activity, with an inhibition zone diameter (IZD) of 16.2 ± 0.2 mm against B. subtilis, and a minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) of 1 and 2% (w/v), respectively. The MBC/MIC ratio between 1 and 4 was observed for the active extracts of coriander seeds, indicating their bactericidal behavior. The liquid chromatography and tandem mass spectroscopy (LC–MS/MS) system using multiple reaction monitoring (MRM) targeted analysis identified 13 phenolic compounds: gallic acid, ellagic acid, gentisic acid, caffeic acid, vanillic acid, o-coumaric acid, sinapinic acid, chlorogenic acid, salicylic acid, ferulic acid, rutin, trans-cinnamic acid, and quercetin. Quantitative differences were observed in the phenolic compounds across the different coriander seed extracts. The TPC was significantly (p ≤ 0.01) and positively correlated with cupric-reducing antioxidant capacity (CUPRAC) (r = 0.92), as well as with ferric-reducing antioxidant power (FRAP) (r = 0.98); furthermore, it showed that the higher level of antioxidant capacity of the coriander seed extracts was significantly (p ≤ 0.05) associated with phenolic compounds such as gallic acid, chlorogenic acid, gentisic acid, ferulic acid, and rutin. However, antibacterial activity and phenolic/antioxidant content were negatively correlated, suggesting that non-polar compounds may impact antibacterial activity. Full article

The present study demonstrates encapsulation of Coriandrum sativum essential oil in chitosan nanoemulsion and its effectiveness against fungal infestation and fumonisin B₁ (FB₁)- and B₂ (FB₂)-mediated biodeterioration of stored rice samples. Mycoflora analysis of different rice varieties revealed fungal occurrence and Fusarium proliferatum-BRC-R2 as the most toxigenic strain with highest FB₁- and FB₂-producing potentiality. GC-MS analysis of Coriandrum sativum essential oil (CEO) revealed linalool as the major component. The CEO-loaded chitosan nanoemulsion (Ne-CEO) was characterized by Scanning electron microscopy, X-ray diffractometry, Dynamic light scattering, and Fourier transform infrared spectroscopy. The Ne-CEO showed better antifungal and anti-fumonisin effectiveness as compared to unencapsulated CEO. The antifungal mechanism was associated with reduced ergosterol content, efflux of ions, proteins, nucleic acids, and destruction of plasma membrane integrity. The in silico interaction of linalool with Fum 1 protein confirmed the molecular action of anti-fumonisin activity. Additionally, the Ne-CEO displayed improved antioxidant activity and promising antifungal and anti-fumonisin activity during in situ investigation in rice samples (Gobindobhog variety) along with inhibition of the deterioration of carbohydrate, protein content, and lipid peroxidation without altering organoleptic properties and seed germination potentiality. Overall, the investigation strengthens the potentiality of Ne-CEO as a novel preservative of stored food commodities. Full article

Pain remains a major clinical challenge due to its complex physiopathology and limited treatment options. In this context, several supplements based on palmitoylethanolamide (PEA) and alpha-lipoic acid (ALA) are known for their neuroprotective properties. ALA-based supplements have shown potential, but concerns about adverse effects persist. This study examines the formulations of two commercial products based on ALA and PEA, IperALA^® and IperALA^® Forte, in which ALA and vitamin D3 are replaced with Coriandrum sativum extract (C. sativum e.s.), N-acetylcysteine (NAC) and glutathione (GSH), assessing improvement of neuroprotective, anti-inflammatory and analgesic properties of the new formulation. Intestinal, blood–brain barrier (BBB), and central nervous system (CNS) models were sequentially stimulated with the test compounds. Both formulations were assessed for cytotoxicity, barrier integrity, permeability, oxidative stress, inflammation, and neuroprotection-related biomarkers. IperALA^® Forte demonstrated superior performance compared to IperALA^® and individual agents. It enhanced cell viability, preserved intestinal and BBB integrity, and improved compound permeability. Notably, it reduced ROS and pro-inflammatory cytokines (TNFα, IL-1), while increasing analgesic markers (CB2R, GABA) in the central system. The replacement of ALA and vitamin D3 with C. sativum, NAC, and GSH in IperALA^® Forte significantly improved the neuroprotective, antioxidant, and anti-inflammatory profile of the supplement. These results indicate a possible connection between the observed neuroprotective properties and the pathways involved in nociception and pain regulation, stating the hypothetical potential relevance of this approach for the treatment of pain-related conditions.

The aim of the study was to investigate the effects of different concentrations (0.15, 0.30, and 0.45 mL/L) of essential oils from coriander seeds (Coriandrum sativum), tarragon (Artemisia dracunculus), and orange peels (Citrus sinensis) on biomass, lipid content, and lipid yield of the strains Yarrowia lipolytica Y-1094, Y. lipolytica YB 423, and Y. lipolytica IFP29. The fatty acid composition of the oils produced by the strains was also determined. The highest biomass (5.38 ± 1.80 g/L) and lipid production (0.98 ± 0.42 g/L) were observed in the presence of Y. lipolytica IFP29 and Y. lipolytica YB 423, respectively. The lipid yield showed the highest value at the level of 0.45 mL/L in the presence of the Y. lipolytica Y-1094 strain. The correlation heat map results indicate that 0.45 mL of tarragon affected biomass and lipid content more than the other essential oils used. Y. lipolytica Y-1094 produced higher levels in terms of myristic acid and palmitic acid in all three essential oil sources than the other strains. The highest oleic acid level of all strains was determined in coriander seed essential oil, and the lowest in tarragon essential oil. The oleic acid level of Y. lipolytica Y-1094 was lower than that of the other two strains in all essential oils. Regarding linoleic acid, the oil level did not have a significant effect in the presence of tarragon and orange peel. Full article

Background/Objectives: Obesity increases reactive oxygen species (ROS), thereby triggering oxidative stress. Coriander seeds contain polyphenolic compounds that act as natural antioxidants to reduce oxidative stress. Coriander seed ethanolic extract has been proven to decrease malondialdehyde and increase catalase activity in the liver of high-fat-diet-fed rats. Thus, coriander seeds are thought to protect against obesity-induced oxidative liver damage; however, their molecular mechanism has not been revealed. Nuclear factor erythroid 2-related factor 2 (Nrf2) and Forkhead Box O3 (FOXO3) are transcription factors involved in cellular antioxidant regulation (e.g., superoxide dismutase/SOD, glutathione peroxidase/GPx expression, and reduced glutathione/GSH) that are negatively regulated by Kelch-like ECH-associated Protein 1 (Keap1) and 14-3-3 protein to maintain cellular homeostasis. This study aimed to analyze the regulation of antioxidant expression through in silico and in vivo experiments. Methods: The in silico study assessed the potential of coriander seed ethanolic extract to inhibit Keap1 and 14-3-3 using molecular docking. Then, the drug-likeness, pharmacokinetics, and toxicity of the top three compounds were analyzed. Meanwhile, the in vivo study investigated how the coriander seed ethanolic extract impacted the level of Nrf2, FOXO3, and their downstream effectors (T-SOD, MnSOD, GPx, and GSH). The in vivo study involved five groups of rats with obesity induced by a high-fat diet that were fed with 100 mg/kgBW coriander seed ethanolic extract for 12 weeks. Results: The in silico tests revealed that shionoside b had the highest potential to inhibit Keap1 (ΔG = −8.90 kcal/mol; Ki = 298.01 nM) and 14-3-3 protein (ΔG = −6.85 kcal/mol; Ki = 9.46 µM). The in vivo tests showed that the Nrf2, FOXO3, MnSOD, and GPx mRNA expression was significantly different between the groups (p < 0.05). Meanwhile, T-SOD, MnSOD, GPx, and GSH activity were not significantly different between the groups (p > 0.05). Nrf2 was significantly correlated with FOXO3 as well as the T-SOD, MnSOD, and GPx activity, and FOXO3 was significantly correlated with the T-SOD, MnSOD, GPx, and GSH activity. Conclusions: In obese rats, coriander seeds tend to increase Nrf2 and FOXO3 expression, which is positively correlated with their downstream enzymatic and nonenzymatic antioxidant activity. This is possibly due to the interaction between the coriander seed phytoconstituents and protein inhibitors (Keap1 and 14-3-3), which contribute to the stability and nuclear mobilization of Nrf2 and FOXO3.

Coriander leaves are widely valued in cooking due to their rich nutrition and unique volatiles, and the flowers are also beneficial for oil extraction from seeds. With the growing interest in LED lights for controlled environments, research on coriander leaves has been reported, but studies on flowers are limited. We investigated the effects of various LED lights, including white (W), red (R), blue (B), and green (G) lights, on flowering. Coriander plants under B light were twice as tall and flowered approximately 4 weeks earlier than those under other lights. However, plants under B light exhibited overgrowth, resulting in fewer flowers at a PAR of 100 µmol·m⁻²·s⁻¹. To reduce this shade avoidance effect, we tested various combinations of W and B light at a PAR of 120 µmol·m⁻²·s⁻¹. The 50:50 ratio of W and B light enhanced growth and accelerated flowering, resulting in twice as many flowers as plants under W light. Total volatile compound levels were higher under W light and highest under 50% W and 50% B lights. Key volatiles specific to coriander leaves, such as (E)-2-decenal, 2-undecenal, and 2-dodecenal, were high under G light at 100 µmol·m⁻²·s⁻¹ of PAR. These findings provide valuable insights into the effects of light on flower development. Full article

Crop aeroponic cultivation still faces issues such as insufficient precision in water supply control and scientifically-based irrigation scheduling. To address this challenge, the present study aims to establish a precision irrigation protocol adapted to the characteristics of crop aeroponic cultivation. Using coriander (Coriandrum sativum L.) as the experimental subject, crop water requirements were estimated utilizing both the FAO56 P-M equation and its revised form. The RMSE between the water requirement measured values and the calculated values using the P-M formula is 2.12 mm, the MAE is 2.0 mm, and the MAPE is 14.29%. The RMSE between the water requirement measured values and the calculated values using the revised P-M formula is 0.88 mm, the MAE is 0.82 mm, and the MAPE is 5.78%. The results indicate that the water requirement values calculated using the revised P-M formula are closer to the measured values. For model development, this study used coriander evapotranspiration as a basis. Major environmental variables influencing water requirement were selected as input features, and the daily reference water requirement served as the output. Three modeling approaches were implemented: Random Forest (RF), Bagging, and M5P Model Tree algorithms. The results indicate that, in comparing various input combinations (C1: air temperature, relative humidity, atmospheric pressure, wind speed, radiation, photoperiod; C2: air temperature, relative humidity, wind speed, radiation; C3: air temperature, relative humidity, radiation), the RF model based on C1 input demonstrated superior performance with RMSE = 0.121 mm/d, MAE = 0.134 mm/d, MAPE = 2.123%, and R² = 0.971. It significantly outperforms the RF models with other input combinations, as well as the Bagging and M5P models across all input scenarios, in terms of convergence rate, determination coefficient, and comprehensive performance. Its predictions aligned more closely with observed data, showing enhanced accuracy and adaptability. This optimized prediction model demonstrates particular suitability for forecasting water requirements in aeroponic coriander production and provides theoretical support for efficient, intelligent water-saving management in crop aeroponic cultivation.

Cilantro (Coriandrum sativum L.) is a popular annual culinary herb grown for its leaves or seeds. With the increase in hydroponic herb production in controlled environments, a need exists for leaf tissue nutrient standards specific to this production system. The objective of this study was to develop comprehensive foliar mineral nutrient interpretation ranges for greenhouse-grown cilantro. Cilantro plants were grown in a hydroponic sand culture system to induce and document nutritional disorders. Plants were supplied with a modified Hoagland’s solution, which was adjusted to individually add or omit one nutrient per treatment while holding all others constant. Deficiency and toxicity symptoms were photographed, after which the plant tissue was collected to determine plant dry weight and critical tissue nutrient concentrations. Nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg), sulfur (S), boron (B), iron (Fe), and zinc (Zn) deficiencies, as well as B toxicity, were induced. Deficiencies of copper (Cu), manganese (Mn), and molybdenum (Mo) were not observed during the experiment. Additional foliar tissue analysis data (n = 463) were compiled to create nutrient interpretation ranges for 12 essential elements based on a hybrid meta-analysis Sufficiency Range Approach (SRA). This approach defines ranges for deficient, low, sufficient, high, and excessive values. For each element, the optimal distribution was selected according to the lowest Bayesian Information Criterion (BIC) value. A Normal distribution best represented K and S. A Gamma distribution best represented P, Ca, Mn, and Mo, whereas a Weibull distribution best represented N, Mg, B, Cu, Fe, and Zn. These interpretation ranges, along with descriptions of typical symptomology and critical tissue nutrient concentrations, provide useful tools for both diagnosing nutritional disorders and interpreting foliar nutrient analysis results of greenhouse-grown cilantro.
