Abstract

A novel pyranoquinoline alkaloid 3,4-dihydro-3-hydroxy-5-methoxy-2,2,10-trimethylpyrano [2,3-b]quinoline named tabouensinium chloride (1), was isolated from the stem bark of Araliopsis tabouensis along with twelve known quinoline alkaloids. In addition, the known flindisol, lupeol and beta-sitosterol glucoside were also identified. Their structures were deduced from spectral data.

摘要

从塔布拟人参（Araliopsis tabouensis）的茎皮中分离出一种新型吡喃喹啉生物碱3,4-二氢-3-羟基-5-甲氧基-2,2,10-三甲基吡喃并[2,3-b]喹啉，命名为氯化塔布因（1），同时还分离出12种已知的喹啉生物碱。此外，还鉴定出了已知的弗林迪索、羽扇豆醇和β-谷甾醇葡萄糖苷。它们的结构通过光谱数据推导得出。
