Flavonoid Glycosides from the Leaves of <i>Glyphaea brevis</i>
نویسندگان
چکیده
A new flavonoid, acacetin-7-O-β-D-glucopyranosyl-(1 → 2)-β-D-glucuronopyranoside (1), together with four known flavonoids, apigenin-7-O-β-D-glucopyranosyl-(1 (2), acacetin (3), acacetin-7-O-β-D-glucuronide (4) and genkwanin-5-O-primveroside (5) were isolated from the leaves of Glyphaea brevis. Their structures elucidated by spectroscopic techniques. The compounds (1 - 5) tested for their antioxidant activity using 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging assay. showed slight negative activities against DPPH radicals.

The bioactive N-butanol fraction of the ethanol extract of the leaves of Cissus ibuensis was fractionated over silica Gel column to give Quercetin 3-O-rutinoside (I) and mixtures of Flavonoids (A2). A2 was fractionated using reverse phase HPLC to give Kaempferol 3-O-α-rhamnopyranosyl (1→6)-β-D-galactopyranoside (II), Kaempferol 3-O-rutinoside(III) and Kaempferol3-O-α-rhamnopyranosyl (1→6)-α-rha...
