Bioactivity analysis of Resveratrol from peanut sprouts using On-line screening HPLC-ABTS

The Peanut sprouts have been used as food for long time in many Asian countries. Among them, resveratrol have bioactivity effects as antioxidant and anticancer. In this work, resveratrol was extracted from peanut sprouts by dipping(extraction time 3h, 25℃) method. And extraction efficiency and amount was identified using on-line screening HPLC-ABTS. From the experimental results, it is evident that the amount of resveratrol(0.310-0.346μg/mL) by 50% aqueous EtOH was higher than any 100% water and EtOH composition. Also, the 100% water extracts sample was low yield 2.040-2.145%. The shown results can be applied as sources for pharmaceuticals and functional material.
