摘要：
Three new quassinoids, 11-alpha-O-(beta-D-glucopyranosyl)-16-alpha-O-methylneoquassin. 1-alpha-O-methylquassin and 12-alpha-hydroxy-13,18-dehydroparain have been isolated and identified from Quassia amara wood. In addition, 16-alpha-O-methylneoquassin and 11-acetylparain were isolated for the firSt time from a natural source. The structures of all compounds were determined by spectroscopical methods as well as by chemical correlations. The reaction products of the NaBH4 reduction and of the alkaline isomerization of parain were also investigated.
