Isolation and structure elucidation of flavonoid glycosides from Solanum verbascifolium

Three flavonoid glycosides including a new one, 7,4′-dimethyl-apigenin-6-C-β-glucopyranosyl-2″-O-α-l-arabinopyranoside (1) were isolated from the leaves of Solanum verbascifolium through bioassay-guided isolation and TRAIL-resistance-overcoming activity of 1 was evaluated.
