After treating the methanol extractive of the leaves of Trachelospermum asiaticum NAKAI var.intermedium NAKAI with ethyl acetate, the mother liquor was extracted with butanol. Three flavone diglycosides (VIII, IX, and X) were isolated from butanol extract by column chromatography over silica gel. VIII and X were respectively identified with the authentic rhoifolin and luteolin 7-neohesperidoside (veronicastroside) in all respects. IX is a new compound, which was elucidated as apigenin 7-gentiobioside.
