摘要
A new acylated flavonoid, 3-O-rhamnocitrin-6-O-benzoyl--D-glucopyranoside (1), together with five known flavonoids, rhamnocitrin (2), pratensein (3), (3R)-7,3-dihydroxy-2,4-dimethoxyisoflavan (4), (3R)-7,2-dihydroxy-3,4-dimethoxyisoflavan (5) and isoliquiritigenin (6), was isolated from Oxytropis ochrocephala Bunge. The structural elucidation of the isolated compounds was primarily based on HRESIMS, IR and 1-D- and 2-D-NMR analyses.
