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.
