Abstract: | Statistical analysis of Chinese medicinal plants, Hamamelidae and Carophyllidae, has been made to the clarification of the ethnopharmacologic data collected nationwide, and hence trend and regularity of these data have been abstracted and quantitatively presented. The main parameters of this study involved: family medicinal coefficient (alpha f) i.e. the radio of medicinal/total genera within a certain family; genus medicinal coefficient (alpha g) i.e. the radio of medicinal/total species within a certain genus; traditional therapeutic usages coefficient (TRI) and extent of traditional therapeutic usages within a certain taxon (beta). The results may be of value to the resources utilization, new drug searching, as well as systematization of traditional Chinese and herbal medicine. |
