Alkaloids from Rauwolfia cubana Stem Bark.
Six indole alkaloids, tetrahydroalstonine, aricine, 16- EPI-affinine, ajmaline, amerovolfine, and amerovolficine have been isolated from the ethanolic extract of the stem bark of RAUWOLFIA CUBANA A. DC. Amerovolfine ( N(alpha)-demethylaccedine) and amerovolficine (16-demethoxy-carbonylpagicerine) are new alkaloids related to 16- EPI-affinine, and their structures have been determined by spectroscopic analysis.
