Identification of the original plant of Tibetan material medica "Zangyinchen"

Correct identification and nomination of the original plants are the first step in exploiting Tibetan herbal medicine. "Zangyingchen",one of the most commonly used Tibetan Materia Medica,is derived from some Gentianaceae. Swertia mussotii is the original plant of"Zangyinchen". S.mussotii and the other eight species that widely used as Tibetan herbal medicine"Zangyinchen"were morphologically and phytochemically compared and their difference was clarified. The reasons of confusion of"Zangyinchen"and identification methods of S.mussotii were discussed. In the phylogenetic frame of Swertia,S.mussotii and S.punicea are closely related,it may be a superior source of medicines with similar qualities to"Zangyinchen".
