Screening Natural Antioxidants in Peanut shell Using DPPH-HPLC-DAD-TOF/MS methods.

Peanutshell, a byproduct in oil production, is rich in naturalantioxidants. Here, a rapid and efficient method using DPPH-HPLC-DAD-TOF/MS was used for the first time to screen antioxidants in peanutshell. The method is based on the hypothesis that upon reaction with 1, 1-diphenyl-2-picrylhydrazyl (DPPH), the peak areas of compounds with potential antioxidant activities in the HPLC […]
