Abstract

The antioxidant activity of the methanol extract of Filipendula hexapetala flowers was assessed by the assay for ferric-reducing antioxidant power (FRAP), the assay for DPPH free radical scavenging ability (DPPH) and the assay for the influence of lipid peroxidation in liposomes, induced by Fe(2+)/ascorbate system and measured by the TBA test (LP). The activity of the investigated extract in all test-systems was found to be significant. The principal constituent responsible for the observed effects was isolated and identified as spiraeoside.

摘要

通过铁还原抗氧化能力（FRAP）测定、DPPH自由基清除能力（DPPH）测定以及Fe(2+)/抗坏血酸体系诱导的脂质体脂质过氧化影响测定（通过TBA试验（LP）测量）来评估六瓣委陵菜花朵甲醇提取物的抗氧化活性。结果发现，所研究提取物在所有测试体系中的活性都很显著。分离并鉴定出了对观察到的效果起主要作用的成分，即绣线菊苷。
