Two compounds isolated from the ethanol extract of the galls of Quercus infectoria. Olivier exhibited nitric oxide (NO) and superoxide [Formula: see text] inhibiting activity. Their structures were established as ellagic acid-4-O.-[β.-D-glucopyranosyl]-10-O.-[β.-D-glucopyranosyl]-(4 → 1)-β.-D-rhamnopyranoside (1) and 2-methyl-3-hydroxymethylene-4,5,6,7,8-pentahydroxynaphthalene (2) on the basis of spectroscopic and chemical evidence.
从没食子（Quercus infectoria. Olivier）虫瘿乙醇提取物中分离得到的两种化合物表现出一氧化氮（NO）和超氧化物[化学式：见原文]抑制活性。基于光谱和化学证据，确定它们的结构分别为鞣花酸-4-O-[β-D-吡喃葡萄糖基]-10-O-[β-D-吡喃葡萄糖基]-(4→1)-β-D-鼠李吡喃糖苷（1）和2-甲基-3-羟基亚甲基-4,5,6,7,8-五羟基萘（2）。
