Chemical Characterization of the Flavonoid Constituents of Cuscuta reflexa

Abstract

The two new compounds were isolated by column chromatography from ethanol extract of the entire plant of Cuscuta reflexa. On the basis of IR, NMR and ES-MS spectroscopic analysis and by chemical transformation, structures of two compounds were elucidated as 3’-methoxy-3,4’,5,7-tetrahydroxy flavone and 3’-methoxy-4’,5,7-trihydroxy flavone-3-glucoside respectively. These isolated compounds were characterized by UV, IR, NMR and mass spectral studies.
