Pharmacognostic identification of radix actinidiae chinensis

Objective: To provide the scientific basis for gruffs identification and utilization of Radix Actinidiae chinensis.Methods: Radix Actinidiae chinensis was studied through the morphological,microscopical and UV spectrum identifications.Results: There were 1-3 stone cell girdle bands in cork layer of root cross section.Sclerotic nests and mucilage cavities which contained calcium oxalate raphides existed in phloem.Endodermis cells separated by radial paries,were fusiform.In powder,port-hole was deep,striation was manifest,and starch grain calcium oxalate acicular crystal was plenty.Conclusion: These characteristics can provide the scientific basis for gruffs identification of Radix Actinidiae chinensis.
