Abstract:
Fourteen flavonoids were isolated and purified from
Epimedium sagittatum by various chromatography techniques such as macroporous adsorbent resin, silica gel, ODS, Sephadex LH-20, HW-40C and semi-preparative HPLC. Their structures were identified by analysis of physicochemical properties and spectral data, and determined as 3′-hydroxy-baohuoside-Ⅱ (1 ), huazhongilexone-7-O -β -D- glucopyranoside (2 ), kaempferol-3-O -α -L -rhamnoside (3 ), baohuoside-Ⅱ (4 ), icariside-Ⅱ (5 ), kaempferol 3,7-di-O-α -L -rhamnopyranoside (6 ), (+)-aromadendrin (7 ), kaempferol 3-O -(2-O -β -D -apiofuranosyl)-α -L -rhamnopyranoside (8 ), sagittatoside A (9 ), 2″-O -rhamnosyl icariside-II (10 ), apigenin-7-O -β -D -glucoside (11 ), quercetin 3-O -β -D -apiofuranoyl-(1→2)-α -L -rhamnopyranoside (12 ), kaempferol (13 ), icariin (14 ). Among them, compound1 is a new compound, while compounds2 ,6 -8 ,11 , and12 were isolated fromE.sagittatum for the first time.
