Isoflavonoid Bioside from Roots of Pueraria hirsuta
摘要
The isoflavone glycoside daidzein-7-O-β-D-glucopyranosyl-(6→1)-O-β-D-glucopyranoside or daidzein-7-O-β-D-gentiobioside was isolated from roots of Pueraria hirsuta. Total isoflavonoids from roots of P. hirsuta showed potent antioxidant capacity with an ORAC value of 19 ± 4 μmol TE/mg.
