摘要
采用超氧阴离子自由基体系、羟基自由基体系、过氧化氢自由基体系及DPPH(二苯代苦味酰肼自由基)自由基体系对决明子水提物的清除自由基活性进行了研究,并同VC进行了比较。结果表明,决明子水提物对超氧阴离子自由基、羟基自由基和过氧化氢自由基均有较好的清除作用,且清除能力高于VC;对DPPH自由基也有较好的清除作用,清除能力和VC相当。
By using superoxide radical system, hydroxyl radical system, H2O2 radical system and DPPH system ,the antioxidation activities of cassia seed water extract were studied and compared with VC. The results showed： cassia seed water extract has better scavenging effect in superoxide radical system, hydroxyl radical system and H2O2 radical system and its scavenging capacity is stronger than VC. It shows better scavenging effect to DPPH with scavenging capacity parallel to VC. Cassia seed water extract is a good sort of natural radical scavenger.
