BACKGROUNDPseudostellaria heterophylla, known for its significant bioactive ingredients, offers potential health benefits. Amounts of bioactive compounds of the tuberous root of cultivated Pseudostellaria heterophylla are sensitive to environmental conditions. We selected 22 sampling sites in Guizhou Province, China, a primary Pseudostellaria heterophylla planting area. We analyzed polysaccharides, water‐soluble extractives, total ash and inorganic elements (Fe, Mn, Zn, Mg and Ca) in Radix Pseudostellariae, and pH, organic carbon (OC), available nitrogen (AN), available phosphorus (AP), available potassium (AK) and inorganic elements in the soil.RESULTSOur study revealed a substantial presence of polysaccharides (85.00–181.00 mg g−1), water‐soluble extractives (47.52–57.63%) and total ash (1.87–3.39%) in Radix Pseudostellariae. Polysaccharides and total ash showed no sensitivity to soil pH. Radix Pseudostellariae collected from soil with pH > 7 exhibited slightly higher levels of water‐soluble extractives, Mg and Ca than that from soil with pH < 5. Conversely, soil with a pH less than 5 had higher OC, AN, AP and AK contents. Water‐soluble extractives in Radix Pseudostellariae were negatively correlated with soil pH but positively correlated with OC and AN.CONCLUSIONThe results imply that the sequestration of soil nutrients over long‐term Pseudostellaria heterophylla cultivation could negatively impact the accumulation of some bioactive ingredients in Radix Pseudostellariae. This study has a profound implication for enhancing the quality of Radix Pseudostellariae of artificially cultivated Pseudostellaria heterophylla. © 2024 Society of Chemical Industry.

Objective To ensure the quality of Perilla frutescens (L.) Britt. and improve the associated benefits for stakeholders, this study analyzed the influences of different circulation channels and stakeholders on the quality, price, and other factors of P. frutescens with consideration to P. frutescens distribution. Method We interviewed the local stakeholders and e-commerce platforms in Oroqen Autonomous Banner and Morin Dawa Daur Autonomous Banner regarding the origin, circulation, distribution, and prices of different medicinal parts of P. frutescens. In addition, the maximum entropy model was used to predict the potential distribution of P. frutescens in the study area. According to the Chinese Pharmacopeia (2020 edition), we measured the content of index components in the collected Perillae Folium, Perillae Caulis, and Perillae Fructus samples and evaluated the quality of the samples by quantitative and cluster analyses. Remote sensing was employed to distinguish and calculate the P. frutescens area in highly suitable regions. The autoregressive integrated moving average model was adopted to analyze the Perillae Fructus price in the study area. Result The results showed 8 value chains for P. frutescens. The cooperation chain between farmers and enterprises in the study area could maximize the benefits for all stakeholders and guarantee the quality of the medicinal materials. The results of the regionalization analysis showed that the most suitable area for planting P. frutescens was the junction between Oroqen Autonomous Banner and Morin Dawa Daur Autonomous Banner. Chemical results showed that Perillae Fructus and Perillae Caulis samples were unqualified and mostly purchased from e-commerce platforms. We identified 5 land types, among which the cultivated land area was 3247.7501 km2. The price of Perillae Fructus in the study area showed a rising trend, although this trend slowed down. Conclusion This study involved various links in the production and circulation of medicinal materials from planting to consumption by consumers, which can help to facilitate the future research on any link. The findings help to guarantee the quality of medicinal materials and benefits of all stakeholders and promote the development of the P. frutescens industry in the study area.
Dendrobium nobile ( D. nobile), an orchid species deeply rooted in traditional medicine, has garnered considerable attention for its potential pharmacological and therapeutic properties. This critical review provides a comprehensive analysis of the bioactive compounds present in D. nobile and explores their diverse pharmacological effects. The phytochemistry of D. nobile has been discussed, highlighting its major constituents and bioactive compounds with specific properties. The pharmacological profile of D. nobile has been investigated in various domains. Notably, its strong antioxidant activity and ability to scavenge free radicals have been shown to support its immune-modulating, anti-inflammatory, and neuroprotective effects. Intriguingly, these orchids display promising anticancer, antidiabetic, cardiovascular, renoprotective, hepatoprotective, and wound-healing properties. The mechanisms underlying these effects were explored, including molecular pathways and signalling cascades. However, factors influencing its chemical composition, such as environmental conditions, cultivation techniques, and postharvest processing, must be considered for consistent therapeutic outcomes. The safety and toxicity profiles derived from acute and chronic toxicity studies were examined. In future studies, exploring the untapped therapeutic potential and elucidating the intricate mechanisms of action are promising. This review underscores the pharmacological richness of D. nobile, revealing its potential to contribute to modern medicine while emphasising the need for further investigation to harness its full therapeutic benefits.
