本文报导从长叶竹柏枝叶中又分得一微量成分, 经波谱测定及X射线衍射分析, 确证为一种新型的失碳二萜双内酯, 命名为长叶竹柏内酯。

关键词: 内酯, 分子结构, Ｘ射线衍射分析, 萜类化合物, 二萜, 竹柏

Fleuryilactone (I) a new type of norditerpene dilactone, was isolated from P. fleuryi. Its structure was established by spectral and x-ray diffraction anal. It is the first natural norditerpene dilactone in which ring C is a five-membered unsatd. lactone with a b-iso-Pr group in the g-position.

Key words: LACTONES, MOLECULAR STRUCTURE, X-RAY DIFFRACTION ANALYSIS, TERPENE, DITERPENES, PODOCARPUS NAGI
