[Pharmacognostic identification of radix actinidiae chinensis].

ABSTRACT

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.
