Abstract

Two new long-chain hydroxyalkyl ferulates, (E)-22-hydroxydocosyl 3-(4-hydroxy-3-methoxyphenyl)acrylate (lyciumol A, 1) and (E)-20-hydroxyeicosyl 3-(4-hydroxy-3-methoxyphenyl)acrylate (lyciumol B, 2), together with eight known compounds, were isolated from the root bark of Lycium chinense Mill. Their structures were elucidated by spectroscopic methods, including 1D, 2D NMR, and HR-ESI-MS analysis.

摘要

从枸杞（Lycium chinense Mill.）根皮中分离得到两种新的长链阿魏酸羟烷基酯，即（E）-22-羟基二十二烷基 3-（4-羟基-3-甲氧基苯基）丙烯酸酯（枸杞醇A，1）和（E）-20-羟基二十烷基 3-（4-羟基-3-甲氧基苯基）丙烯酸酯（枸杞醇B，2），以及八种已知化合物。通过光谱方法对其结构进行了阐明，包括一维、二维核磁共振以及高分辨电喷雾电离质谱分析。
