Abstract
A new tetracyclic triterpenoid compound named as mastichinoic acid A (1) was isolated from Mastich. The structure was established as 3,7-dioxo-11β-hydroxy-5α-tirucalla-8,24(Z)-dien-26-oic acid by various spectroscopic techniques including MS, 1D, and 2D NMR and HRTOFMS.
摘要
从乳香中分离出一种名为乳香新酸A（1）的新型四环三萜化合物。通过质谱（MS）、一维（1D）和二维（2D）核磁共振以及高分辨飞行时间质谱（HRTOFMS）等多种光谱技术确定其结构为3,7-二氧代-11β-羟基-5α-香树脂烷-8,24（Z）-二烯-26-酸。
