Phenolic compounds from the rhizomes of Dioscorea bulbifera

Chem Biodivers. 2011 Nov;8(11):2110-6. doi: 10.1002/cbdv.201000279.

Abstract

One new bibenzyl, 7, and one new diarylheptanone, diobulbinone A (18), together with sixteen known compounds, 1-6 and 8-17, have been isolated form the rhizomes of Dioscorea bulbifera. Their structures were elucidated by NMR and MS analyses. Compound 7 showed high antioxidant capacity in FRAP assay and DPPH radical-scavenging activity.
