Herpes simplex virus type 1 (HSV-1) remains a significant pathogen, particularly in immunocompromised patients. The emergence of drug-resistant strains necessitates alternative therapeutic agents. Lentinula edodes (LE), Hypsizygus marmoreus, and Pleurotus eryngii are edible mushrooms with recognized medicinal properties. However, their effects on drug-resistant HSV-1 remain unclear. This study characterized metabolites from high-temperature/high-pressure (121 °C) water extracts of fresh and dried fruiting bodies and evaluated anti-HSV-1 activities using in vitro and in silico approaches. Metabolic profiles were analyzed by electrospray ionization–quadrupole time-of-flight mass spectrometry. Antiviral activity against HSV-1 KOS (wild-type) and HSV-1 dxpiii (drug-resistant) strains was assessed by plaque assays and qPCR. Molecular docking and network pharmacology were performed on candidate compounds. LE extract from dried mushroom tended to show the highest levels of selected major bioactive constituents, along with greater antioxidant activities. All extracts significantly inhibited viral infection and gene expression in both strains. LE extract from dried mushroom modulated the expression of NFKB1 and IL6. Molecular docking analysis revealed that eritanidine showed a predicted binding affinity to HSV-1 DNA polymerase (−7.95 kcal/mol). Additionally, eritanidine, 5′-methylthioadenosine, and 3-indoleacrylic acid were predicted to interact with TNF and MAPK1. Several compounds also demonstrated favorable drug-likeness properties. Overall, these mushroom extracts are promising natural sources of antiviral agents against HSV-1, including drug-resistant variants. Full article

Foeniculum vulgare Mill. (fennel) is an edible and medicinal plant cultivated worldwide. Owing to its distinctive aroma and diverse biological activities, its essential oils (EOs) have been widely investigated. However, available data predominantly focus on cultivated fennel or commercial EOs, while comprehensive investigations of wild-growing Mediterranean populations—particularly comparisons among different plant parts—remain scarce. In this study, EOs obtained by hydrodistillation from stems, leaves, flowers, and fruits of native Croatian fennel, were chemically characterised using gas chromatography-mass spectrometry (GC-MS), while antimicrobial activity was evaluated using the disc diffusion method against four bacterial strains. Additionally, the volatile profiles of fennel hydrolates were determined by headspace solid-phase microextraction (HS-SPME) and GC-MS analysis. Fennel flowers gave the highest EO yield (1.95%), followed by mature fruits (1.43%), whereas significantly lower yields were obtained from leaves (0.69%) and stems (0.58%). Trans-anethole was identified as the dominant constituent (from 40.96% in stems to 80.71% in fruits), while α-phellandrene predominated in stem EO (42.77%). Hydrolate volatile profiles were more complex—particularly leaf hydrolate, where 29 compounds were identified. The principal constituents were trans-anethole (39.58–57.40%) and fenchone (16.01–28.80%), while the highest content of estragole was observed in fruit hydrolate (6.56%). The EOs demonstrated moderate antimicrobial activity, showing effectiveness exclusively against Escherichia coli, likely attributable to high phenylpropanoid (primarily trans-anethole) and fenchone contents.

The fruits of Lycium chinense are important medicinal and edible resources with multiple bioactive functions, including hepatoprotective, antioxidant, and immunomodulatory effects. Although this species is widely distributed in China and exhibits abundant germplasm resources, systematic evaluations of fruit quality variation among wild germplasm remain limited, restricting the selection and breeding of superior resources. In this study, eight wild germplasm resources of L. chinense were collected from the eastern coastal regions of China, including Liaocheng (LC), Rugao (RG), Dafeng (DF), Suzhou (SZ), Qidong (QD), Dongtai (DT), Jingjiang (JJ), and Sheyang (SY). A total of 29 fruit quality-related traits, including fruit size, flavonoids, soluble sugars, vitamin C, and amino acids, were analyzed. Significant differences were observed among germplasm resources in both fruit size and internal quality. Comprehensive evaluation based on principal component analysis and entropy weight–grey relational analysis indicated that SY and LC ranked highest. SY exhibited smaller fruits but superior nutritional quality, with higher levels of soluble protein, vitamins, and amino acids. In contrast, LC showed larger fruits and higher contents of polysaccharides and total phenolics, along with stronger antioxidant capacity. Overall, SY and LC represent promising germplasm resources for breeding and utilization of L. chinense. Full article

Wild edible fruits play an important role in supporting food security, nutrition, and traditional knowledge systems in rural communities, yet their diversity and uses remain insufficiently documented in many parts of Thailand. This study aimed to investigate the diversity, utilization, and ethnobotanical significance of wild edible fruit species in Kut Chum District, Yasothon Province. Ethnobotanical data were collected through semi-structured interviews and field surveys with local informants, and quantitative indices, including the Cultural Importance Index (CI), Fidelity Level (%FL), and Informant Consensus Factor (ICF), were applied to evaluate species significance and medicinal agreement. A total of 71 species belonging to 33 families were recorded, with most species consumed as fresh fruits and a subset used for medicinal purposes. Several species, such as Irvingia malayana Oliv. ex A.W.Benn., Phyllanthus emblica L., and Syzygium cumini (L.) Skeels exhibited high cultural importance, reflecting their key roles in local diets. High ICF values across therapeutic categories indicated strong consensus in ethnomedicinal knowledge. Additionally, 44 species not used medicinally in the study area were reported as medicinal in other regions, highlighting spatial variation in knowledge systems. These findings emphasize the importance of wild edible fruits as multifunctional resources contributing to food and nutritional security. Integrating culturally important species into conservation and sustainable use strategies may support biodiversity preservation and the continuity of traditional ecological knowledge. Full article

Lactarius hatsudake is an ecologically and economically significant wild edible mushroom in southern China. To elucidate its population genetic diversity, differentiation, and evolutionary history, we analyzed 172 fruiting bodies from eight geographic populations (AQ, BS, DZ, JS, NC, PT, SG, YX) across seven provinces in the western and eastern regions of southern China using five highly polymorphic simple sequence repeat (SSR) markers. Combined with STRUCTURE clustering, discriminant analysis of principal components (DAPC), unweighted pair group method with arithmetic mean (UPGMA), and analysis of molecular variance (AMOVA), the results revealed high polymorphism across the studied loci (mean PIC = 0.842). A total of 75 alleles were identified, averaging 15 alleles per locus. At the population level, the mean effective number of alleles (Ne) was 4.023, and the mean unbiased gene diversity (uH) was 0.768. The NC population exhibited the highest genetic diversity (uH = 0.796), whereas the BS population showed relatively lower diversity (uH = 0.647). Clustering analyses (STRUCTURE, DAPC, and UPGMA) consistently identified two distinct genetic clusters (K = 2). Cluster I consisted of populations AQ, PT, BS, and SG, while Cluster II was composed of the remaining four populations. Notably, individuals from AQ and NC displayed significant genetic admixture, suggesting a transitional zone. AMOVA revealed that the majority of genetic variation (83%) resided within populations and 17% among populations. Moderate population differentiation (ENA-corrected global Fst = 0.102) and admixture signals suggest non-negligible connectivity among populations. Full article

Monkey kola is a common name given to the edible wild relatives of the West African kolanut. These are neglected and underutilized indigenous tropical fruit species growing in the West and Central African forests. Knowledge of the nutrient and antinutrient composition of the fruits is highly inadequate. In this study, mature fruits of two wild monkey kola species (Cola pachycarpa and Cola lepidota) were collected and evaluated for phytochemical, proximate, vitamin and mineral composition. There were significant (p < 0.05) differences in the proximate, mineral, and vitamin composition of the two species. C. lepidota was richer in moisture, protein, fat, alkaloids, phosphorus, calcium, and iron, while C. pachycarpa was richer in ash content, crude fibre, flavonoids, magnesium, potassium, sodium, zinc, vitamin B2, vitamin B3, vitamin C, vitamin A, and vitamin E. However, there were no significant (p > 0.05) differences between the two monkey kola species in their saponins, tannins and phytate composition. The abundance of a wide variety of minerals, vitamins and other bioactive compounds in both kola species justifies their wide consumption by natives in regions where they grow. The fruits of these species should be fully exploited for their potential health benefits. Full article

India, home to 4 biodiversity hotspots, hosts 675 wild species used for nutritional and therapeutic purposes. Wild edible fruits are highly valuable for their rich content of health-beneficial compounds, such as polyphenols, carotenoids, and vitamins. The shift in modern lifestyles has increasingly impacted human health. Several factors contribute to heightened oxidative stress, which underpins the development of non-communicable diseases (NCDs). Endometriosis, one of these conditions influenced by oxidative stress, currently lacks a definitive cure, leaving patients reliant on hormonal and surgical treatments. According to the WHO, 10% of girls and women worldwide are affected by endometriosis, often experiencing severe symptoms. This review explores the role of oxidative stress in the progression of endometriosis, its pathophysiology, and the effects of polyphenols found in wild Himalayan fruits, including various phenolic acids, flavonoids, stilbenes, and lignans. It also examines their synergistic effects with other non-polyphenolic compounds in reducing these biomarkers, such as inflammatory enzymes, pro-inflammatory cytokines, and estrogen receptors, and in modulating pathways like NF-κB, PI3K/AKT, among others, based on preclinical and clinical studies. Additionally, the review highlights key wild fruit species native to the Indian Himalayas, details their nutritional and phytochemical profiles, and assesses their potential, individually and synergistically, as functional foods or nutraceuticals for non-invasive treatment options for endometriosis.

Wild edible fruits (WEFs) represent an important yet underutilised component of biodiversity-based nutrition and functional food research. This structured narrative review critically synthesises current evidence on the phytochemical composition and nutritional relevance, biological activities, and sustainability dimensions of WEFs, with emphasis on fruit pulp as the primary edible tissue. A systematic search strategy following PRISMA-based principles was applied to enhance methodological transparency; however, due to high heterogeneity in species, analytical methods, and outcome measures, quantitative meta-analysis was not feasible. The review integrates compositional data (phenolics, carotenoids, tocopherols, sterols, vitamin C, and minerals) with reported bioactivities, while explicitly distinguishing between in vitro assays, in vivo studies, and limited clinical evidence. Particular attention is given to analytical variability, bioavailability constraints, dose–response relationships, and translational limitations that affect the interpretation of antioxidant and other health-related claims. Beyond bioactivity, the manuscript contextualises WEFs within socio-economic, conservation, and sustainable food system frameworks. By combining chemical characterisation, evidence hierarchy, and sustainability analysis, this review provides a critical and multidisciplinary perspective that advances understanding of WEFs and identifies priorities for future research, including standardised methodologies and well-designed human intervention trials.

Inonotus hispidus is an important medicinal and edible fungus within the “Sanghuang” category, featuring a broad host range and rapid fruiting body growth. However, its wild resources are currently threatened by overharvesting. Simultaneously, large-scale jujube (Ziziphus jujuba) cultivation generates substantial pruning waste, often burned. This study explored the feasibility of using jujube wood as a cultivation substrate for I. hispidus. Three I. hispidus strains, Z1, Z2, and ZL, were cultivated on substrates with varying proportions of jujube wood replacing cottonseed hulls. The biological efficiency, nutritional components, active compounds, and free amino acid profiles of the resulting fruiting bodies were analyzed. Non-targeted metabolomics was used to investigate global metabolic changes. Results indicated that all strains successfully colonized the jujube-based substrates and produced fruiting bodies. Strain ZL exhibited the highest biological efficiency and the shortest growth period on the 48% jujube wood substrate, while others showed significantly increased triterpenoids and flavonoids content. Metabolomic analysis revealed substrate-dependent and strain-specific alterations in metabolic pathways, particularly in amino acid biosynthesis, the TCA cycle, and secondary metabolism. This study confirms jujube wood as a viable alternative substrate for the edible (ZL) and medicinal (Z1, Z2) cultivation of I. hispidus, providing a sustainable production method while establishing a valuable utilization pathway for jujube wood waste.

Global food security and dietary diversity depend on identifying novel and sustainable food sources. Wild edible plants (WEPs) traditionally used in Mediterranean regions offer considerable potential due to their rich history of use. Here, ethnobotanical knowledge was systematically compiled for the fruits and cones of five taxa (Arbutus unedo, Prunus spinosa, Quercus spp., Pinus spp. and Rosa spp.), documenting alimentary uses, preparation and conservation methods across diverse food categories. Analysis of over 2800 traditional use reports identified 54 distinct alimentary uses from 16 categories, with raw consumption and sweet preserves being the most prevalent. Rosa spp. exhibited the highest diversity of uses (36), whereas the family Pinaceae showed the lowest (19). Statistically significant associations between individual fruits and specific food preparations were also observed, offering guidance for innovative product development. Information on processing methods that preserve nutritional components, along with documentation of potential harmful effects and the methods to mitigate them, was collected, providing essential guidance for developing safe and functional alimentary products. Together, traditional knowledge, regulatory adherence, and sustainable practices create new opportunities to develop innovative, safe, culturally grounded, and sustainable food products that enrich diets and preserve cultural and ecological heritage.

This study documents the diversity, cultural significance, medicinal use, and economic value of WEPs among the Tai Yoy community in Akat Amnuai District, Sakon Nakhon Province. Field surveys, interviews, and market observations recorded 78 species belonging to 42 families, with 52 species represent new records for the province. Fruits and leaves were the most commonly used parts, while multifunctional species such as Curcuma angustifolia Roxb., Phyllanthus androgynus (L.) Chakrab. & N.P.Balakr., and Spondias pinnata (L.f.) Kurz were highly valued for both dietary and medicinal purposes. Quantitative analyses, including the Cultural Food Significance Index (CFSI), fidelity level (FL), and Jaccard’s similarity index (JI), revealed strong cultural consensus on key species and regional patterns shaped by ecological and sociocultural factors. Market surveys identified 25 species contributing to household income, highlighting the economic importance of WEPs and the potential risks of overharvesting. The study emphasizes the need for sustainable management, including cultivation of high-demand species, to reduce pressure on wild populations while supporting food security and traditional knowledge. These findings provide a comprehensive baseline for future ethnobotanical research, conservation planning, and the sustainable use of WEPs in northeastern Thailand. Full article

Core germplasm, a strategically selected subset of the original germplasm, aims to maximize the representation of genetic diversity within the entire collection. Establishing a germplasm resource bank is essential for the effective management and sustainable utilization of genetic resources. This study developed a core germplasm repository for Hypsizygus marmoreus, a commercially important mushroom species, to capture the genetic diversity of the original collection with a minimal sample size. Genetic diversity and cluster analyses were conducted on 57 representative strains of H. marmoreus, including both cultivated and wild accessions from different regions, using 15 pairs of simple sequence repeat (SSR) markers. DNA molecular identity cards were generated for all germplasms, and cultivation trials with agronomic trait assessments were performed on 24 core accessions. A total of 115 distinct alleles were identified, with genetic similarity coefficients ranging from 0.70 to 1.00. Clustering at a similarity threshold of 0.76 classified the strains into five groups. The core germplasm panel, comprising 24 accessions (42.11% of the total collection), retained full allelic diversity and preserved the genetic and phenotypic variability of the original population, confirming its suitability for parental selection in breeding programs. unique molecular identity codes were developed for each H. marmoreus germplasm by integrating SSR marker profiles with data on geographical origin, fruiting body color, and cultivation traits. These were converted into DNA molecular ID codes, providing a reliable system for rapid identification and traceability of germplasm resources. The findings offer a valuable reference for breeding improvement and the protection of edible fungal varieties with independent intellectual property rights. Full article

Hericium coralloides is a valuable medicinal and edible mushroom renowned for its unique bioactive compounds. This study focuses on the isolation of a wild strain (SH001) exhibiting promising cultivation potential and health promoting properties. A wild fungal strain from the Tibetan Plateau was isolated and identified as a novel H. coralloides based on its morphological and molecular characteristics. The optimal growth conditions were found to be 30 °C, pH 7.0, fructose as the preferred carbon source, and yeast extract as the optimal nitrogen source. Nutritional analysis revealed that the fruiting bodies were rich in protein (15.4 g/100 g dry weight), dietary fiber (34.7 g/100 g dry weight), and minerals, while being low in fat (3.5 g/100 g dry weight). The most abundant amino acids were glutamic acid, followed by aspartic acid. The polysaccharides exhibited significant antioxidant activity, with ABTS⁺ scavenging comparable to that of Vitamin C (Vc), achieving a clearance rate of 96.95% at concentrations between 0.25–5.00 mg/mL. At a concentration of 5 mg/mL, the DPPH and OH radical scavenging activities reached their peak (83.77% and 67.31%, respectively), along with the highest iron ion reducing capacity (FRAP value: 4.43 mmol/L. Polysaccharides also exhibited notable anticancer activity, inhibiting HepG2 liver cancer cells and MDA-MB-468 breast cancer cells, with IC₅₀ values of 3.896 mg/mL and 2.561 mg/mL, respectively. This study demonstrates that wild H. coralloides can be successfully cultivated in vitro. In conclusion, the fruiting bodies possess substantial nutritional value, and the polysaccharides extracted from them show promising antioxidant and anticancer activities, particularly against HepG2 liver cancer cells and MDA-MB-468 breast cancer cells.

Wild edible plants, historically valued for their medicinal properties, can be a sustainable source of food, cosmetics, and pharmaceuticals. The blue berries of Prunus spinosa L., known as blackthorns, have antioxidant, astringent, and antimicrobial benefits. To preserve these properties after harvesting, understanding the best storage methods is essential. In this study, blackthorns were preserved using different methods (air-drying, freezing, or freeze-drying) to determine the optimal procedure for preserving their antioxidant activity. The fruits were extracted using a 50:50 (V/V) mixture of ethanol and water. The different extracts were phytochemically characterized for their phenolic content and antioxidant activity. The Folin–Ciocalteu test revealed total phenolic contents of 7.97 ± 0.04, 13.99 ± 0.04, and 7.39 ± 0.08 (mg GAE/g raw material) for the three types of extracts, respectively. The total flavonoid contents were 2.42 ± 0.16, 3.14 ± 0.15, and 2.32 ± 0.03 (mg QE/g raw material), respectively. In line with the polyphenol analysis, the antioxidant activity as determined by DPPH method was higher for the frozen extract, with a value of 91.78 ± 0.80%, which was confirmed by the ROS test on keratinocytes. These results show that both air-drying and freeze-drying processes negatively impact the preservation of antioxidant activity in blackthorns, suggesting that freezing may be the best preservation method before bioactive compound extraction.
