Abstract

Fourteen alkaloids were isolated from the stem bark of Melodinus tenuicaudatus Tsiang et P. T. Li. Eleven of them were identified as known alkaloids, namely, scandine (2), Δ14-eburnamine (4), vindolinine N b-oxide (5), 11-methoxytabersonine (6), vindolinine (7), epi-vindolinine N b-oxide (8), hazuntine (9), compactinervine (10), 11-hydroxytabersonine (11), Δ14-vincine (12), and normacusine B (14). Two alkaloids were new: 10-hydroxyscandine (1), and the dimer, tenuicausine (3); their structures were elucidated by spectroscopic and chemical methods. One alkaloid (13) occurring in trace amounts, could not be identified.
