Abstract

Nine new fatty acid derivatives, including seven methoxylated (1, 2, and 4-8) and two hydroxylated (3 and 9) fatty acids, have been isolated from the ethanol extract of the stem bark of Fraxinus sieboldiana. Their structures were determined by spectroscopic methods including IR, MS, 1D, and 2D NMR experiments. The 3- or 9-methoxylated fatty acids are reported for the first time in nature.

摘要

从光叶榉茎皮的乙醇提取物中分离出九种新的脂肪酸衍生物，包括七种甲氧基化脂肪酸（1、2和4 - 8）和两种羟基化脂肪酸（3和9）。它们的结构通过光谱方法确定，包括红外光谱（IR）、质谱（MS）、一维（1D）和二维（2D）核磁共振实验。3 - 或9 - 甲氧基化脂肪酸在自然界中首次被报道。
