Abstract

A new lupane-type triterpene, 3alpha-hydroxy-lup-20(29)-en-24-oic acid, was isolated from the methanolic extract of "Erytrean-type" resin of commercial frankincense together with the known 3alpha-hydroxy-olean-12-en-24-oic acid (alpha-boswellic acid) and 3alpha-hydroxy-urs-12-en-24-oic acid (beta-boswellic acid). Their structures were characterized on the basis of chemical and spectral evidence including two dimensional NMR experiments and mass spectrometric techniques.

摘要

从市售乳香“厄立特里亚型”树脂的甲醇提取物中分离出一种新的羽扇烷型三萜，即3α-羟基羽扇-20(29)-烯-24-酸，同时还分离出了已知的3α-羟基齐墩果-12-烯-24-酸（α-乳香酸）和3α-羟基乌苏-12-烯-24-酸（β-乳香酸）。它们的结构是根据化学和光谱证据确定的，包括二维核磁共振实验和质谱技术。
