The flavonoids, luteolin, luteolin 7-0-/3-d-xyloside and cynaroside, were isolated by El-Moghazi et al. (1979) and orientin and vitexin by Akunzemann and Herrmann (1977). Quercetin-3-glucuronide, rutin, isoorientin, isovitexin and apigenin-7-glucoside have been reported from aniseed (Ozguven, 2000). Figure 18.2 depicts the structure of flavonoids in aniseed. [Pg.336]

Fig. I6A A methanoiic extract of Lespedezae herba (4) contains more highly glycosidated flavonoids (R, range 0.05-0.35) such as kaempferol- and/or isorhamnetin-rhamno-glucoside and rutin (Tl). The EtAc extract (5,6) contains the enriched yellow zones of flavon-C-glyco.sides such as isoorientin (R, -- 0.S/T3), orientin (R, — 0.65/T3) overlapped by isovitexin, a.s well as flavonol-O-glycosides such as lespedin, hyperoside, isoquerdtrin and querdtrin (Rf 0.6-0.8).

Our investigation on Malaysian H. diffusa [31] as well as H. her-bacea also yielded quercetin 3-0-glucopyranoside (21) together with quercetin 3-0-rutinoside (24). From H. herbacea, we have found kaempferol 3-O-rutinoside (25), kaempferol 3-O-glucoside (26), kaempferol 3-O-arabinopyranoside (27) and quercetin 3-0-galactoside (28) [7]. We have also reported kaempferitrin (29) from H. verticillata [32] and isovitexin (30) from the aerial parts of H. dichotoma [33]. [Pg.1064]

Standards catechin and gallic acid, 3,4 dihydroxybenzoic add (protocatechuic acid), chlorogenic acid, rutin were purchased from Across Organics (France), p-coumaric acid, isovitexin and quercetin 3-fi-D-glucoside were obtained from Fluka Chemical Company (France). [Pg.133]
