Flavonoids from Daphne giraldii Nitsche.

A new flavonoid glycoside, 5-methoxy-7-beta-D-glucopyranosyl-(-)-afzelechin (1), together with seven known flavonoids, 7-O-beta-D-glucopyranosyl-(-)-epiafzelechin (2), sakuranin (3), genkwanin (4), 4',5-dihydroxy-3',7-dimethoxyflavone (5), luteolin-3',7-dimethyl ether-5-beta-D-glucoside (6), and luteolin-7-methyl ether-5-beta-D-glucoside (7), were isolated from the stem barks of Daphne giraldii. Their structures were identified on the basis of spectroscopic analysis. Compounds 2, 3, and 5-8 were first reported from the titled plant.
