| 摘 要： | 为研究生姜及其制品中的具有清除自由基能力的有效成分,本文研究了姜酮(Zingerone)、脱氢姜酮(Dehydrozingerone)、姜酚肟(Gingeroloxime)对超氧阴离子(superoxideanionfreeradical,SARF)和DPPH(1,1-diphenyl-2-picrylhdrazyl)的清除作用。结果表明姜酮和脱氢姜酮对两种自由基都有显著的清除作用,量效关系明显。姜酚肟对于超氧阴离子的清除能力较弱。这些结果说明姜酮是生姜及其制品中清除自由基的一种有效成分。而脱氢姜酮有望作为一种新的抗氧化剂。

| Abstract: | This paper deals with the scavenging effects of zingerone, dehydrozingerone and gingerol oxime on superoxide anionfree radical (SARF) and 1,1-diphenyl-2-picrylhdrazyl (DPPH)free radical. The results show that both zingerone anddehydrozingerone have a noticeable ability to scavenge both of the two free radicals. The more their content, the higher theirabilities are. The ability of gingerol oxime on the SARF scavenging is not obvious. All those results indicate that Zingerone is oneof these constituents in fresh ginger and its product that contribute to scavenge free radicals. Furthermore, the result also indicatethat dehydrozingerone have the potentiality to be a new antioxidant additive. |
