Article Abstract
Objective: To study the chemical constituents from the whole plant of Delphinium caeruleum.
Methods: The chemical constituents were isolated and purified by silica gel and Sephadex LH-20 column chromatography. The structures of the isolated compounds were elucidated by spectroscopic analysis and physicochemical properties.
Results: Twelve compounds were isolated and purified from the ethanol extract of Delphinium caeruleum. They were identified as β-sitosterol( 1),kaempferol( 2),quercetin( 3),isovanillic acid( 4),apigenin( 5),luteolin( 6),8-methoxy-5,7,3’,4’-tetrahydroxy-flavone( 7),β-daucosterol( 8),kaempferol-3-O-β-D-glucoside( 9),3,5-dihydroxy-4’-methoxyflavone-7-yl-O-β-D-glucopyranosyl-( 1→4)-α-L-rhamnopyranoside( 10),rutin( 11) and sucrose( 12).
Conclusion: Compounds 1 ~ 12 are isolated from this plant for the first time.
