A new isoflavone glucoside from Blepharis ciliaris
Phytochemical study of the aerial parts of Blepharis ciliaris. led to the isolation of one new isoflavone glucoside [ genstein-7-O-(6''-O-E-caffeoyl-β-D-glucopyranoside)] (1), along with seven known compounds: methyl veratrate, methyl vanillate, protocatechuic acid, naringenin-7-O-(3''-acetyl-6''-E-p-coumaroyl-β-D-glucopyranoside), naringenin-7-O-(6''-E-p-coumaroyl-β-D-glucopyranoside), api-genin-7-O-(6''-E-p-coumaroyl-β-D- glucopyranoside), and acteoside. Their structures were established on the basis of detailed analyses of chemical, and spectral data. The antioxidant activity was evaluated.
