Abstract

• Chemical investigation of tuber of Dioscorea bulbifera Linn. (Local name Put-sar-u) led to the isolation of bibenzyl derivative namely, 3-methoxy-4, 3', 5' -trihydroxybibenzyl (1). The structure of isolated metabolite was elucidated by spectroscopic techniques, particularly by 1D and 2D NMR spectroscopy and mass spectrometry. Antioxidant and antimicrobial properties of various solvent extracts was studied by using DPPH radical scavenging assay and agar-well diffusion method respectively.
