| Abstract: | The chemical constituents from Gypsophila elegans(Caryophyllaceae)were studied and six flavonoids were isolated.The structures of these compounds were identified by spectral data as isoorientin-2″-O-α-L-arabinopyranosyl (1),apigenin-6-C--7-O-β-D-glucopyranoside (2),apigenin-8-C-β-D-glucopyranoside (3),saponarin (4),apigenin-7-O-sophoroside (5) and isovitexin-2″-O-β-D-glucopyranoside (6). Compound (4) was first isolated from this plant and others five compounds were obtained from Caryophyllaceae family for the first time.Their antioxidant activities were also investigated by DPPH method,1 showed antioxidant activity. |
