Untiring Researches for Alternative Resources of Rhizoma Paridis

Abstract

Rhizoma Paridis (RP, ), a traditional Chinese medicine, is the rhizoma of Paris polyphylla var. yunnanensis (PPY) or P. polyphylla var. chinensis which are widely used as important raw materials for several Chinese patent drugs. However, the wild resources of these herbs have become less and less due to their slow-growing characteristics and previously excessive excavation. This review covers untiring investigations on alternative resources of RP by our research group over the past decades, including non-medicinal parts of PPY as well as other plants of Liliaceae and Liliflorae families. The arial parts of PPY and the whole plants of Trillium kamtschaticum might be alternative resources for RP based on the fact that they shared the same or similar saponins and bioactivities.
