摘要：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.
