Two rare megastigmane glucosides, 3- and 9-O-β-D-glucopyranosides of (3S, 5R, 6R, 7E, 9S) -megastigman-7-ene-3, 5, 6, 9-tetrol (1 and 2), were isolated from Hypericum erectum THUNB. Their structures were established on the basis of chemical and spectral data. This is the first report of the isolation of each megastigmane derivative from Guttiferae plant.
