摘要
One rare tetracyclic macroline-type indole alkaloid,named rauvoyunine A(1),and two new picraline-type alkaloids rauvoyunines B and C(2 and 3)were isolated from the aerial parts of Rauvolfia yunnanensis.Their structures were elucidated on the basis of extensive spectroscopic analysis.Compounds 2 and 3 were evaluated for their in vitro cytotoxicity against five human tumor cell lines.
