This article attempts to comprehensively assess plants from the Apiaceae family, such as Apium graveolens, Daucus carota or Petroselinum crispum, as raw plant materials with potential uses in cosmetic products with anti-inflammatory and antibacterial effects. The work compares the phytochemical profiles and activity of extracts and ferments from the roots of these plants obtained during fermentation using kombucha. The antioxidant properties of the tested extracts, the effect on the intracellular level of free radicals and their cytotoxicity towards skin cells were compared. Their anti-inflammatory and antibacterial properties were also assessed. The ABTS and DPPH tests indicated the highest antioxidant potential of the carrot ferments, achieving a 55.75% and 74.6% reduction of these radicals, respectively. The resazurin and Neutral Red assays indicated that in most cases, sample concentrations not exceeding 2.5% did not cause a cytotoxic effect, and in the case of a 20-day parsley ferment, they could increase viability by over 40%. The disk diffusion method indicated growth inhibition zones of over 20 mm for some bacteria. The minimum inhibitory concentrations for seven different bacterial strains ranged from 200 to 400 µg/mL. Anti-inflammatory properties were determined using the ELISA method, assessing the level of interleukins 1β, 6 and 10. The obtained results indicate a higher amount of phytochemicals, a lack of cytotoxic effect at lower concentrations of the tested samples and significantly stronger antioxidant, antibacterial and anti-inflammatory properties of the ferments compared to the extracts. This effect depends on the concentration and fermentation time used. Full article

The unintentional release of nanoparticles in the atmosphere and their targeted application to improve plant productivity requires detailed study. The translocation features of copper and gold nanoparticles applied by spraying in the concentration range of 1–100 mg/L in Petroselinum crispum (Mill.) tissues during a 10-day experiment were investigated. Atomic absorption spectrometry and inductively coupled plasma atomic emission spectroscopy showed that copper and gold nanoparticles applied to the leaves’ surface could accumulate in plant organs. A dose-dependent increase in the content of copper and gold in the aerial parts of parsley was revealed. The content of copper in leaves treated with nanoparticles was 1–2.3 times higher than the control, while the content of gold exceeded control values 2–116 times. The effect of nanoparticles on plants’ biochemical composition was assessed. The antioxidant tests showed an ambiguous response at exposure to metal nanoparticles. Copper nanoparticles at the applied concentration consistently reduced both chlorophyll and carotenoid content. Gold nanoparticles enhanced the chlorophyll and carotenoid level at low concentrations (1 mg/L) and significantly inhibited it at higher concentrations. The parsley exposed to nano-copper remained safe for human consumption, but parsley containing more than 14.9 mg/kg of gold may adversely affect human health. Full article

Petroselinum crispum (Mill.) Fuss (Apiaceae), popularly known as parsley, is a ubiquitous aromatic herb used for culinary and medicinal purposes worldwide. In addition to the richness in nutrients, several bioactive secondary metabolites, especially the flavone apigenin and its glycosides, have been described in this species. Parsley has already been shown to have several health-promoting activities, such as antithrombotic, antihypertensive, and hypolipidemic properties. The multiple studies conducted in animal models so far suggest this species is a potential source of cardioprotective agents. This review provides up-to-date information and perspectives on the potential of parsley and its bioactive compounds for the development of nutraceutical products and drugs for promoting cardiovascular health. It includes not only a discussion of parsley’s reported bioactivities but also the knowledge of supplements and food additives developed as innovative parsley-based products. Full article

The status of parsley as a well-known folk medicine noted for its nutritional and medicinal properties prompted the exploration of its potential as a functional food and natural remedy. The paper aims to investigate the potential of parsley to enhance muscle function and alleviate psoriasiform dermatitis, eventually establishing it as a natural, well-tolerated alternative with specific benefits for both muscles and skin. This study examines the tolerability of parsley in a cohort of 937 participants by assessing immunoglobulin G (IgG) reactions. The findings reveal high tolerability, as 96.26% of participants experienced no adverse effects. Among the 902 individuals lacking hypersensitivity, 37.02% reported muscle cramps, with a notable 15.02% reduction observed in the subgroup consuming parsley juice. In the subset of 32 subjects with dermatitis, the application of parsley extract ointment led to a significant decrease in dermatological parameters (redness, thickness, scaling). While the control group exhibited improvements, statistical significance was not observed. Notably, four categories of affected area reduction were identified, with scaling demonstrating the most pronounced impact. The results propose that parsley holds promise for favorable tolerability, contributing to the alleviation of muscle cramps and presenting an effective alternative in dermatitis treatment. Nonetheless, sustained validation through long-term studies is imperative to substantiate these preliminary findings. Full article

Background and Objectives: Paracetamol overdose is a significant global issue due to its widespread use, which can lead to a lack of awareness regarding its potential side effects. Paracetamol can harm the liver, possibly resulting in liver failure. Conversely, this study employed extracts from Petroselinum crispum (PC), known for its rich content of bioactive compounds, with demonstrated antioxidant properties shown in previous research as well as protective effects against various diseases. The primary objective of this study was to investigate the potential protective effects of Petroselinum crispum on altered hematological and biochemical parameters in the blood of rats exposed to paracetamol. Materials and Methods: The study involved twenty Wistar rats divided into four groups. Different groups of male rats were administered PC extract at 200 mg/kg body weight daily for 15 days, along with a standard reference dose of paracetamol at 200 mg/kg. The study assessed hepatoprotection capacity by analyzing liver enzymes such as aspartate aminotransferase (AST), alanine aminotransferase (ALT), bilirubin, albumin, and lipid profiles. Renal safety was evaluated through creatinine, urea, uric acid, lactate dehydrogenase (LDH), and total protein. Additionally, histopathological examinations of the liver and kidneys were conducted. Results: Following Paracetamol overdose, there were reductions in hemoglobin levels, serum total protein, albumin, and uric acid. Paracetamol overdose also elevated levels of several blood biomarkers, including creatinine, urea, nitrogen, ALT, AST, triglycerides, LDH activity, white blood cell count, and platelet count compared to the control group. However, using an ethanolic extract of Petroselinum crispum significantly mitigated the severity of these alterations and the extent of the effect correlated with the dose administered. Parsley extract helped prevent proteinuria and low hemoglobin, which are common side effects of Paracetamol. Conclusions: Therefore, parsley may hold promise in managing liver and kidney conditions—particularly in addressing proteinuria. Ultimately, these results may have implications for human health by potentially mitigating paracetamol-induced renal, hepatic, and hematological toxicity. Full article

Monitoring the dynamics of the spore bank of arbuscular mycorrhizal fungi (AMF) is essential for the sustainable management and protection of agroecosystems. The most common method for extracting AMF spores from soil is the wet-sieving technique (WST). However, this method has many disadvantages. In this study, we modified the WST using new approaches: the ultrasound wet-sieving technique (UWST) and the ultrasound centrifuge technique (UCT). We enumerated and compared the numbers and quality of spores obtained from WST, UWST, and UCT to validate the new modified techniques. We extracted AMF spores from the rhizospheres of different plants, including wheat (Triticum aestivum L.), bean (Phaseolus vulgaris L.), tomato (Solanum lycopersicum L.), pepper (Piper nigrum L.), parsley (Petroselinum crispum Mill.), and turfgrass (Lolium perenne L.) collected from the Van Lake basin, Turkey. The highest and lowest AMF spore numbers were observed in wheat and turfgrass rhizospheres. The UCT allowed for the extraction of the highest number of spores from all rhizospheres, followed by the UWST and WST. The UWST and WST allowed for the extraction of similar spore numbers from wheat, pepper, parsley, and turfgrass rhizospheres. Beyond the high extracted spore number, UCT was shown to be a fast and low-material-consuming approach. These findings demonstrate that the UCT can be used to efficiently extract AMF spores in future research. Full article

Petroselinum crispum (Mill) Fuss is an aromatic plant belonging to the Apiaceae family and used in gastronomy as a spice. Several studies have been developed in leaves but studies are limited in seeds, especially the essential oils obtained from seeds. The aim of this study was to determine the phytochemical profile of the volatile compounds of this essential oil by gas-chromatography–mass spectrometry (GC-MS) in order to evaluate its phytotoxic activity on Lactuca sativa seeds and to carry out an in silico analysis on the target enzyme of the herbicide glyphosate 5-enolpyruvylshikimate 3-phosphate synthase (EPSP). The essential oil was obtained by steam distillation for two hours and then was injected into a GC-MS, the phytotoxic assay was carried out on Lactuca seeds and the in silico evaluation on the EPSP synthase focused on the volatile compounds similar to glyphosate, docking analysis, and molecular dynamics to establish the protein–ligand stability of the most active molecule. The chromatographic analysis revealed 47 compounds, predominated by three compounds with the most abundant percentage in the total content (1,3,8-ρ-menthatriene (22.59%); apiole (22.41%); and β-phellandrene (15.02%)). The phytotoxic activity demonstrated that the essential oil had a high activity at 5% against L. sativa seed germination, inhibition of root length, and hypocotyl length, which is comparable to 2% glyphosate. The molecular docking on EPSP synthase revealed that trans-p-menth-6-en-2,8-diol had a high affinity with the enzyme EPSP synthase and a better stability during the molecular dynamic. According to the results, the essential oil of P. crispum seeds presented a phytotoxic activity and might be useful as a bioherbicide agent against weeds. Full article

Parsley (Petroselinum crispum Mill.) is a vegetable that has many benefits for human health, and its cultivation is increasing. In order to carry out breeding studies in parsley, genotypes should be characterized in terms of some characteristics. In this study, some phytochemical properties of 18 different parsley genotypes were revealed, and their genetic diversity was determined with the iPBS (Inter Primary Binding Site) marker system. In the study, the polymorphism rate was 31.9%, the mean PIC (Polymorphic Information Content) was 0.17, and the similarity coefficients were between 0.87 and 0.99. The number of subpopulations was determined as two, and 10 markers were detected at expression levels of 19–33% related to phytochemical properties. The results of this study show that there is a phytochemical and genetic variation in parsley. Parsley genotypes with certain phytochemical properties and genetic structures can be used more effectively in breeding programs. Full article

Proline is an amino acid that increases plant tolerance to abiotic and biotic stresses, but the effects of its application can be influenced by many factors. The present study investigated the effects of time and the number of applications of this amino acid on the yield of root parsley in field conditions. The experimental material comprised of two parsley cultivars (Petroselinum crispum (Mill.) Nyman ex A.W. Hill), ‘Halblange’ and ‘Sonata’. The parsley plants were sprayed with proline (1000 mg L⁻¹) at growth stages determined according to the BBCH scale: BBCH 15–16 (I: 5–6 leaf phase), BBCH 41 (II: roots start to widen, diameter > 0.5 cm), and BBCH scale 42–43 (III: roots are 20–30% of the typical diameter), including I + II, II + III, and I + II + III. The time and number of proline applications affected the weight of leaves and the total and marketable yield. The amino acid spraying increased the average number of plants during harvest in the ‘Halblange’ but decreased the number in the ‘Sonata’ in all applications. Using proline twice or three times reduced the total essential oil content and modified its composition. The most beneficial effect in terms of the composition was achieved by using proline twice at stages II + III, even in ‘Sonata’, where the values were lower in the other treatments than in the control. Spraying three times did not give better results in terms of the composition and content of the essential oil. However, the use of this amino acid did not affect the total and marketable yield of the roots or the leaf weight of the parsley compared to the control. Our study showed that the time of the proline application may be more important than the number of applications, and the results may be cultivar-dependent. Full article

Composts and biochar individually or in combination have been used for decades for improving soil quality and health. To date, very few studies have focused on the quality of food produced using compost-biochar mixtures. In this study, the use of biochar to improve the fertilization effect of composts and the quality of greenhouse-grown parsley was investigated by adding biochar to composts made from a mixture of broiler chicken wastes and sugar bagasse, sawdust, urban trees, napier grass, or cotton residues. On average, highest N and P contents were obtained with the bagasse- and sawdust-biochar substrates. The tree-biochar substrate led to increased levels of phenolic compounds in parsley compared to all the other organic substrates. Full article

The herbal plant Petroselinum crispum (P. crispum) (Mill) is commonly available around the world. In this study, the leaves of the herbal plant P. crispum were collected from the central region of Al-Kharj, Saudi Arabia, to explore their in vitro pharmacological activity. Essential oil from the leaves of P. crispum was isolated using the hydrodistillation method. The composition of P. crispum essential oil (PCEO) was determined using Gas chromatography-mass spectrometry (GC-MS). A total of 67 components were identified, representing approximately 96.02% of the total volatile composition. Myristicin was identified as the principal constituent (41.45%). The in vitro biological activity was assessed to evaluate the antioxidant, antimicrobial, and anti-inflammatory potential of PCEO. PCEO showed the highest antimicrobial activity against Candida albicans and Staphylococcus aureus among all the evaluated microbial species. In vitro anti-inflammatory evaluation using albumin and trypsin assays showed the excellent anti-inflammatory potential of PCEO compared to the standard drugs. An in silico study of the primary PCEO compound was conducted using online tools such as PASS, Swiss ADME, and Molecular docking. In silico PASS prediction results supported our in vitro findings. Swiss ADME revealed the drug likeness and safety properties of the major metabolites present in PCEO. Molecular docking results were obtained by studying the interaction of Myristicin with an antifungal (PDB: 1IYL and 3LD6), antibacterial (PDB: 1AJ6 and 1JIJ), antioxidant (PDB: 3NM8 and 1HD2), and anti-inflammatory (3N8Y and 3LN1) receptors supported the in vitro results. Therefore, PCEO or Myristicin might be valuable for developing anti-inflammatory and antimicrobial drugs. Full article

Soil amendments, such as composts and biochar, are currently widely used as substrates in container gardening. Although different types of wastes have been used in composting, formulating growing mediums for specific plants using different materials is necessary. In the present study, organic substrates comprising mixtures of (a) broiler chicken wastes composted with sugar bagasse, sawdust, urban tree, napier grass, or cotton residues, and (b) five different proportions of biochar (0%, 15%, 30%, 45%, and 60%) were used to produce mineral and flavonoid-rich parsley plants. The sawdust-based substrate led to the highest yields (27.86 g pot⁻¹ on average), regardless of the amount of biochar added; however, this substrate resulted in plants with no appreciable antioxidant activities. Plants grown using the tree-based substrate had moderate yields (16.95 g pot⁻¹), and the highest phenolic levels (e.g., 7.93 mg GAE g⁻¹) and antioxidant activities (DPPH scavenging activity over 11.17 g TE g⁻¹). Such activities were better described by the presence of apigenin-7-apiosylglucoside and diosmetin-apiosylglucoside. Moderate yields were also obtained with the cotton-based substrate; however, such yields were only obtained at biochar proportions greater than 30%; this substrate led to the highest K contents (47.19 g kg⁻¹). The lowest yields (3.20 g pot⁻¹) and N (20.96 g kg⁻¹), P (1.33 g kg⁻¹), K (33.26 g kg⁻¹), and flavonoid (13.63 mg CE g⁻¹) contents were obtained with the napier-based substrate. However, this substrate led to the production of parsley plants with the highest levels of anthocyanins (0.40 mg CGE g⁻¹), which may have accumulated as stress sensors and defense components. The bagasse-based substrate also led to high yields and appreciable flavonoid contents with 60% biochar. In most cases, no linear relationship was found between the biochar amount and the chemical parameters evaluated. Overall, the substrates formulated using urban tree residues had higher suitability for parsley development than those formulated using sugar bagasse, sawdust, napier grass, or cotton residues.

Celery (Appium graveolens L.) and parsley (Petroselinum crispum (Mill.) Fuss) are herbs utilized in the everyday diet as spices and culinary flavorings, often used in the chemical and medicinal industries. Despite the knowing benefits of different plants from the Apiaceae family, their chemical composition is closely associated with various extrinsic factors. Environmental loading with trace elements (TEs) can modify a plant’s metabolic pathways, change bioactive compounds production, cause plant pollution, and consequently provoke human health issues. Therefore, we established this research aiming to unravel the linkage between TEs accumulation and phenolic status in celery and parsley. Higher As, Cd, and Ni levels were observed in celery, which was followed by greater DPPH^∙ radical scavenging activity and higher coumarins content. Contrary, parsley accumulated chromium to a greater extent, was richer in flavonoids, apigenin, and its glucosides. No significant difference between species was found in total phenolic contents, where ferulic and chlorogenic acid dominated in both species. A direct relationship between TEs and selected secondary metabolites was proven by the standardized major axis model. Besides abundant bioactive compounds, analyzed plant species showed a moderate hazard index in the children population, since the hazard index was higher than 1. Therefore, future perspectives should be turned towards the production of genotypes with a lower potential for toxic elements accumulation, so the health benefits of plant food will be more prominent.

This paper describes the antigerminant capacity of water extracts of silver fir needles created by means of hydrodynamic cavitation processes. Fir needles (2 kg fresh weight) collected in the winter were blended and crushed in ice, poured in water only (120 L) and processed in a controlled hydrodynamic cavitation device based on a fixed Venturi-shaped reactor. The A. alba water extract (AWE), comprising an oil-in-water emulsion of silver fir needles’ essential oil (100% AWE), was diluted in distilled water to 75% and 50% AWE, and all aqueous solutions were tested as antigerminant against four weeds and four horticultural species and compared to control (distilled water). This study shows the effective inhibitory effect of pure AWE on germination, which mainly contains limonene (15.99 ng/mL) and α-pinene (11.87 ng/mL). Seeds showed delayed germination and inhibition but also a reduction in radicle elongation in AWE treatments as compared to control. This combined effect was particularly evident in three weeds (C. canadensis, C. album and A. retrofllexus) while horticultural species showed mainly effects on the radicle elongation as found in L. sativa, P. crispum and S. lycospermum, which showed on average 58%, 32% and 28%, respectively, shorter radicles than in the control. P. sativum was not affected by AWE, thus raising the hypothesis that seed characteristics and nutrition reserve might play a role in the resistance to terpenes inhibitory effect. Full article

Herbal medicine and its therapeutic applications are widely practiced in northeastern Morocco, and people are knowledgeable about it. Nonetheless, there is a significant knowledge gap regarding their safety. In this study, we reveal the toxic and potential toxic species used as medicines by people in northeastern Morocco in order to compile and document indigenous knowledge of those herbs. Structured and semi-structured interviews were used to collect data, and simple random sampling was used as a sampling technique. Based on this information, species were collected, identified, and herbarium sheets were created. The collected data were analyzed using two quantitative indices: informant consensus factor (ICF) and fidelity level (Fl), as the degree of these indices give an insight into the level of toxicity of a given plant. The results revealed the knowledge of 55 species belonging to 36 families. The most represented families were Apiaceae, Asteraceae, Solanaceae, and Fabaceae. Furthermore, the majority of the species cited were herbs (67%), and the most common toxic parts were seeds, followed by leaves and roots. According to the informant consensus factor, death (0.81%) had the highest agreement, followed by the urological (0.76%) and skin (0.75%) categories. The most significant plants in terms of fidelity level were Solanum sodomaeum L. and Nerium oleander L. for death, Arisarum vulgare O. Targ. Tozz., Mentha spicata L., and Morus alba L. for the digestive category, Petroselinum crispum (Mill.) Fuss. and Citrus x aurantium L. for cardiovascular category, Urtica dioica L. for skin category, Datura stramonium L, and Ephedra altissima Desf. for neurological category, and finally Crocus sativus L. for general and unspecified category. This work highlights a valuable traditional knowledge of poisonous and potential poisonous plants in northeastern Morocco. Further phytochemical and toxicological research is needed to determine the safety of these prized herbs. Full article
