To study the chemical constituents from the whole plant of Delphinium caeruleum.
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.
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).
Compounds 1 ~ 12 are isolated from this plant for the first time.
