Verticilliside, a new flavone C-glucoside from Enicostemma verticillatum

Verticilliside (1), a new flavone C-glucoside, has been isolated from the ethyl acetate soluble fraction of Enicostemma verticillatum and its structure is assigned on the basis of the spectroscopic data. 5,7,4'-Trihydroxyflavone 8-C--d-glucopyranoside (2) and isoorientin 3'-O-methyl ether (3) have also been isolated for the first time from this species.
