Studies on Chemical Constituents of Ethyl Acetate Portion of Incarvillea arguta

Abstract:

Objective:To study the chemical constituents of the ethyl acetate portion of Incarvillea arguta. Method: The ethyl acetate portion were isolated and pured by silica gel column chromatography, HP-20 and Sephadex LH-20.Their chemical structures were elucidated by spectral data(¹H-NMR,¹³C-NMR). Result: Five compounds were isolated from the ethyl acetate portion. They were identified as suberosenol A( 1 ),suberosenol B( 2 ),suberosenone( 3 ),kaempferol-7-O-α-L-rha mnoside( 4 ),ferulic acid( 5 ). Conclusion: All compounds were isolated from this plant for the first time.
