Megastigmane Glycosides from Trichosanthes anguina L.
Using various chromatography methods, four megastignane glycosides, corchoionoside B (1), icariside B5 (2), (3R,9S) 3,9-dihydroxymegastigman-5-ene 9-O-β-D-glucopyranoside (3), and icariside B1 (4) were isolated from the leave of Trichosanthes anguina L. Their structrures were elucidated by 1D- and 2D-NMR. All these compounds were reported from the genus Trichosanthes for the first time.
Keywords: Trichosanthes anguina L., Cucurbitaceae, Corchoionoside B, Icariside B5, (3R,9S) 3,9-dihydroxymegastigman- 5-ene 9-O-β-D-glucopyranoside, Icariside B1.
