Abstract

Two new compounds, lysidiside S (1) and 7-O-(+)-peltogynol-beta-d-glucopyranoside (2), together with six known phenolic glycosides (3-8) were isolated from the bark of Lysidice brevicalyx Wei. The structures of these compounds were characterized by chemical and spectroscopic methods. The antioxidant activities of compounds 1-8 were evaluated, and compound 3 exhibited remarkable antioxidant activity at concentrations of 10(-4), 10(-5), and 10(-6) mol/l.

摘要

从短萼仪花（Lysidice brevicalyx Wei）的树皮中分离得到了两种新化合物，仪花苷S（1）和7 - O -（+）- 佩尔托苷元 - β - D - 吡喃葡萄糖苷（2），以及六种已知的酚苷（3 - 8）。通过化学和光谱方法对这些化合物的结构进行了表征。对化合物1 - 8的抗氧化活性进行了评估，化合物3在浓度为10^(-4)、10^(-5)和10^(-6) mol/L时表现出显著的抗氧化活性。
