Journal Title:World Journal of Pharmaceutical Research
Abstract


A new Isoflavone glycoside 5, 7, 4? trihydroxy-6-methoxyisoflavone-7-O-?-L-rhamnopyranosyl(1?4)O-?-L-arabinopyranosyl-4?-O-?-Dxylopyranoside (A) was isolated from the roots of prosopis spicigera Linn. together with two known compounds Wogonin (B) and Diosmetin (C). The structure A was elucidated on the basis of various chemical degradations, color reactions and spectroscopic analysis viz. UV, IR, 1 H NMR and 13 C NMR. Compound A exhibited higher radical scavenging activity in the 1,1-diphenyl-2-pycryl-hydrazyl (DPPH) assay system and also screened against various bacteria an d fungi.
