Three new indole alkaloids, 10‐methoxy‐16‐de(methoxycarbonyl)pagicerine ( 1 ), (5 β )‐17‐ O ‐deacetyl‐5,11‐dimethoxyakuammiline ( 2 ), and ((16 S ,19 E )‐ N 1 ‐(hydroxymethyl)isositsirikine ( 3 ) were isolated from the roots of Rauvolfia yunnanensis , together with seven known alkaloids. The structures of the new compounds were elucidated by in‐depth spectroscopic and mass‐spectrometric analyses.
