Study on Antioxidant Activity of Proanthocyanidins from Peanut Skin
The research aimed to provide scientific basis for developing Proanthocyanidins from peanut skin. In this study, the antioxidant activity of Proanthocyanidins form peanut skin was studied at different system (O2-•, •OH and DPPH•) in vitro, with Vc. For O2-•, •OH and DPPH•, the IC50 of Proanthocyanidins form peanut skin was 0.143mg/mL, 0.097mg/mL and 0.274mg/mL; the IC50 of Vc was 0.163mg/mL, 0.097mg/mL and 0.306mg/mL. The result showed that proanthocyanidins from peanut skin had stronger antioxidant activity than Vc, and that Proanthocyanidins would be a effective natural free radical scavenger.
