Abstract:

A new flavonol triglycosides, Quercetin 3-O-α-L- rhamnopyranosyl (12)- β -D-galactopyranosyl (1 - 6)-β-D-glucopyranoside, was isolated from the leaves of, Azadirachta indica together with two known flavonol glycosides, Quercetin 3 - O- β - D-galactopyranoside-7 - O- β - D-glucopyranoside and Quercetin-3 - O - β - D-xyloside. The structures were determined by means of RF values, UV-Visible, ELMS, FAB+MS, 1H NMR, and 13C NMR.
