Abstract

From the resinous exudate of Heliotropium sinuatum (family Boraginaceae), a new compound: 4-(3',5'-dihydroxynonadecyl)phenol 1, together with eight previously described flavonoids, were isolated and their antioxidant activities were assessed by quenching measurements with ABTS and DPPH cation radicals.

摘要

从紫花天芥菜(紫草科)的树脂状渗出物中,分离出一种新化合物:4-(3',5'-二羟基十九烷基)苯酚1,以及八种先前已描述的黄酮类化合物,并通过用ABTS和DPPH阳离子自由基进行猝灭测量来评估它们的抗氧化活性。
