Resource Distribution and Pharmacognostics Analysis of Authentic Medicinal Herbs Su Pinellia ternata in Anhui Province
Objective:To address the problem of endangered wild resources and the decreasing scale of artificial cultivation of the authentic medicinal herb Su Pinellia ternata in Anhui Province and explore strategies to promote its industrialization and sustainable development.Methods:A survey of the distribution of Su P.ternata resources was conducted using methods such as literature review,field investigations,mass interviews,and sample analysis.The collected samples were subjected to pharmacognostics analysis,morphologic,microscopic,thin-layer chromatographic,and extract analysis.Results:In Sipu Town,Suixi County,Anhui Province,small-scale cultivation of P.ternata was found,while wild P.ternata was sporadically distributed in fruit tree groves,fields,and slopes in other counties and districts.The total distribution area is approximately 6.18×105 m2,with total reserves of about 49.93 tons of herb.Microscopic identification revealed numerous starch granules in the powder of Su P.ternata,with diameters ranging from 2 to 20 μm;bundles of calcium oxalate needle crystals,with lengths of 20 to 110 μm;mainly threaded conduits.In the thin-layer chromatography of the test samples,spots of the same color were observed at the corresponding positions of the four amino acid reference substances,the P.ternata reference medicinal material,and P.ternata from other regions.The results conform to the identification criteria of P.ternata in the 2020 edition of the Chinese Pharmacopoeia,proving that Su P.ternata and P.ternata in the 2020 edition of the Chinese Pharmacopoeia share the same origin.The highest extract content was found in wild P.ternata collected in Dangshan County,Anhui Province.Conclusion:The authentic medicinal resource of Su P.ternata urgently needs protection and rational development and utilization.The ecological environment of Dangshan County is suitable for the growth of wild P.ternata and the accumulation of effective components,indicating good germplasm resources.
