[Flavonoid glycosides from dried and nearly ripe fruits of Evodia rutaecarpa]

To study the chemical constituents from the dried and nearly ripe fruits of Evodia (Euodia) rutaecarpa.The compounds were separated and purified by solvent and chromatographic methods. Their structures were identified by spectroscopic techniques.Fifteen compounds were separated from the normal butanol extracts of the 70% aqueous ethanol extract of the dried and nearly ripe fruits of E. rutaecarpa. Among of them, four compounds were reported in the essay and identified as diosmetin-7-O-beta-D-glucopyranoside (1), isorhamnetin-3-O-rutinoside (2), diosmin (3) and chrysoeriol-7-O-rutinoside (4).Compounds 1, 3 and 4 were separated from the dried and nearly ripe fruits of E. rutaecarpa for the first time.
