  • A dihydrostilbene derivative compound, namely 3,3-dihydroxy-5-methoxybibenzyl or batatasin III (1) was isolated from the yam peel of Dioscorea alata L. The structure of compound 1 has been elucidated based on spectroscopy UV-Vis, 1D and 2D NMR Analysis. The IC50 of DPPH radical scavenging of this compound (206.82 μg/mL) lower than ethyl acetate extract (109.99 μg/mL), but higher than methanol extract (893.59 μg/mL).
