摘要Five new indole alkaloids, rauvoloids A-E (1-5), together with two known ones, raucaffrinoline (6) and perakine (7) were isolated from the leaves of Rauvolfia yunnanensis. Their structures were elucidated by extensive spectroscopic methods. Structurally, rauvoloids A (1), B-C (2-3) and D (4) with unusual substitution patterns (no substitution, Cl and (1E)-3-oxo-butenyl, respectively) at C-20, are the first examples of perakine-type alkaloids with C-18 and C-22 skeletons.
