Peanut top parts of leaves and stems are feasible to be consumed as a vegetable. Peanut
kernels of Tainan 9 were aquatic- and field-cultivated for 30 days and the top parts were
harvested for three times at a 10-day interval. The highest total phenolics, epicatechin
and caffeic acid contents in leaveswere detected in the second harvest of aquatic-cultivation.
In comparison, higher epicatechin and caffeic acid contents were observed in leaves of
aquatic-cultivation than the field-cultivated leaves. The reducing powers, total equivalent
antioxidant capacity and inhibitory activities against AGEs formation varied with a close
dependence on total phenolics contents. Based on SDS–PAGE analysis, all harvested aquatic-
and field-cultivated peanut leaves were effective in inhibition of albumin glycation. It is
of merit to demonstrate that multiple harvests of the green top parts of peanuts bear
potent antioxidant and antiglycative activities
