Abstract

Trichosides A (1) and B (2), new withanolide glucosides, have been isolated from the n-butanolic fraction of the 75% methanolic extract of aerial parts of Tricholepis eburnea. Their structures were elucidated through spectroscopic analysis including ESI-MS, 2D NMR and acid hydrolysis.

摘要

从绵毛旋覆花地上部分75%甲醇提取物的正丁醇部位分离得到了新的维A醇苷类化合物旋覆花苷A（1）和旋覆花苷B（2）。通过包括电喷雾电离质谱（ESI-MS）、二维核磁共振（2D NMR）和酸水解在内的光谱分析确定了它们的结构。
