Isolation and Characterization of Flavonoid and Other Compounds from Seeds Extract of Calpurnia Aurea

The study was undertaken to isolate and characterize flavonoid and other compounds from seeds extract of Calpurnia aurea . Three compounds were isolated from this medicinal plant, it were identified as flavonoid compound G1 named: 2-(4-(2-hydroxyethyl)phenyl)-4H-chromen-4-one, compound P2 named: 1-(2-(3-((E)-buta-1,3-dienyl) cyclopentyl)ethyl)benzene and compound C3 named: (E)-methyl 14-hydroxy-10-methyltetradec-2-enoate. Its structures determinations were based on 1 H, 13 C NMR spectral measurements. In this study, proton and carbon signals were assigned by means of 2D NMR spectral methods for compound P2.
