摘要: 超声辅助提取红果参中的抗氧化活性物质并用D-101大孔树脂纯化,以原花青素为指标测定抗氧化活性物质含量,研究了提取物对羟基自由基、超氧阴离子自由基和亚硝酸盐体系的清除作用以及对油脂氧化体系的抑制作用。结果表明:红果参果实提取物表现出了对羟自由基、超氧阴离子自由基及亚硝酸盐的优异的清除能力,对油脂氧化有极好的抑制作用,对自由基的清除率及抗油脂氧化能力与提取物中原花青素质量浓度均呈剂量正相关效应。

Abstract: The antioxidant components of Hong Guo Shen were ultrasonically extracted and purified using D-101 macroporous resin.The content of the extracts was determined using proanthocyanidins as index.The antioxidant activity of the purified extracts was investigated by testing scavenging effects of ·OH,O2,NO2 and against the peroxidation of oils.The results showed that the purified extracts exhibited excellent ability to remove ·OH,O2,NO2 and good inhibitory effect to peroxidation of oils.Furthermore,the antioxidant activity increased with the increasing of the concentration of extracts.

Key words: Hong Guo Shen, proanthocyanidins, extractions, antioxidant activity
