Abstract

Phytochemical investigation of the methanol extract of the wood of Cunninghamia konishii resulted in the isolation of two new acidic labdane-type diterpenoids, 12(S)-hydroxy-15,16-epoxylabda-8(17),13-dien-19-oic acid (1) and 12(S)-hydroxy-15,16-epoxylabda-8(17),13-dien-18-oic acid (2), along with one known labdane-type diterpene, 7,13E-labdadien-15-ol (3). Their structures were determined by analysis of spectroscopic data and comparison with the data of known analogues.

摘要

对台湾杉木木材甲醇提取物进行植物化学研究，分离得到两个新的酸性半日花烷型二萜类化合物，12(S)-羟基-15,16-环氧半日花-8(17),13-二烯-19-酸（1）和12(S)-羟基-15,16-环氧半日花-8(17),13-二烯-18-酸（2），以及一个已知的半日花烷型二萜，7,13E-半日花二烯-15-醇（3）。通过光谱数据分析并与已知类似物的数据进行比较确定了它们的结构。
