本文报导从安徽产三尖杉弱碱部份分得五种高刺桐类型生物碱, 其中两种新生物碱经UV, IR光谱分析分鉴定为:2-O-乙基表福建三尖杉碱(2-O-ethglepicephalofortuneine)和2-O-乙基福建三尖杉碱(2-O-ethylcephalofortuneine)。

关键词: 生物碱, 分子结构, 光谱分析, 三尖杉硷

Two new homoerythrina alkaloids were isolated from C. fortunei (Cephaltaxaceae), collected in Anhui Province, China, and shown to be 2-O-ethylepicephalofortuneine (I) and its' epimer, 2-O-ethylcephalofortuneine. Three known bases, namely, taxodine, methyltaxodine, and 3-epischehammericine were also isolated and identified. The 1H NMR spectral data is given.

Key words: ALKALOID, MOLECULAR STRUCTURE, SPECTROGRAPHIC ANALYSIS, CEPHALOTOXINUM
