Title: [Chemical Constituents of Ethyl Acetate Fraction from Hypericum ascyron].
Abstract: To study the chemical consituents of Hypericum ascyron.The constituents were isolated and purified by chromatography on silica gel; the structure of the compound was determined by MS and NMR spectral analysis.On the basis of spectroscopic analysis and comparison with the reported data, they were identified as hyperoside( 1),hypercalin B( 2),hypercalin C( 3),1,7-dihydroxyxanthone( 4),2,3-dimethoxyxanthone( 5),1-hydroxy-7-methoxyxanthone( 6),rutin( 7),kaempferol( 8),toxyloxanthone B( 9),quercetin( 10),quercitrin( 11),β-daucosterol( 12) and β-sitosterol( 13).Compounds 2,3,6 and 9 are obtained from this plant for the first time.
