Comparison of Antioxidant Activity in Five Fruit Wine of Guangxi in China

Abstract

With reference to VC, for the first time, this thesis studied the antioxidant activity in five fruit wine of Guangxi by five different systems（NO2－, •OH, O2-•,DPPH• and reduction ability）and the scoring method. Study results indicated: Firstly, five fruit wine had strong antioxidant ability in vitro except the Rosa laevigata michx wine had no scavenging effect on O2-•. Especially Fructus phyllanthus wine and the Rosa laevigata michx wine had scavenging effect on •OH as the same as VC and more reduction ability than VC. What’s more, Sour plum wine had more scavenging effect on O2-•than VC; Secondly, by scoring method, the following was the antioxidant activity in order: Fructus rhodomyrti wine
