继前文￣（１）工作，又从胀果甘草根茎中获得了十七个化合物。其中五个鉴定为１：蔗糖，２：４’，５，７－三羟基－８－异戊烯－黄铜，３：甘草素，４：芒柄花素，５：光甘草酮。化合物１，４，５为首次从该植物中获得。在三个体外氧化体系中观察了它们的抗氧化活性。２，３，５显示出显著的清除的活性，５对Ｈ＿２Ｏ＿２诱导的溶血具有良好的抑制作用，３，５对（ＨｐＤ＋ｈｖ）诱导的溶血的抑制作用比某些典型的抗氧化剂都好 Following the previous work (1), 17 compounds were obtained from the roots and stems of Glycyrrhiza uralensis. Five of them were identified as 1: sucrose, 2:4’, 5,7-trihydroxy-8-isopentene-brass, 3: glycyrrhizin, 4: formononetin, 5: photoglycyrrhizin. Compounds 1,4,5 were obtained from this plant for the first time. Their antioxidant activity was observed in three in vitro oxidation systems. 2,3,5 showed significant clearance activity, 5 had a good inhibitory effect on H 2 O 2 -induced hemolysis, and 3, 5 pairs (HpD + hv) induced hemolysis was better than some typical antioxidants.
