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.

Dihydromyricetin-zinc(II) complex was synthesized. The scavenging activity of DPPH radical, hydroxyl radical, superoxide anion radical and alkane radical by dihydromyricetin-zinc(II) complex were determine, moreover compared with Vc. The results showed that dihydromyricetin-zinc(II) complex possessed strong scavenging activities on DPPH•, hydroxyl radical, superoxide anion radical and alkane radical with correspounding maximum scavenging rate 74%, 70% , 65% and 50% at the concentration from 0.1 mmol/L to 0.5 mmol/L, respectively, which were higher than Vc. These results suggested that dihydromyricetin-zinc(II) complex would be an effective free radical scavenger.
