摘  要:采用多种分离材料包括硅胶、Sephadex LH-20和反相RP-18从泽漆的95%乙醇提取物的正丁醇部位分离得到12个化合物,经过波谱学方法分别鉴定为Helioscopin D(1),Isofraxidin(2),Swertiamarin(3),13-Car-boxyblumenol C(4),4,4′-dimethoxy-3′-hydroxy-7,9′,7′9-diepoxyligan-3-O-β-D-glucopyranoside(5),(+)-Syringa-resinol-4′-O-β-D-glucoside(6),2S,3R-2,3-Dihydro-2-(4-hydroxy-3-methoxyphenyl)-3-hydroxymethyl-7-methoxy-benzofuran-5-(trans)propen-1-ol-3-O-β-glucoside(7),Quinquenin L1(8),(6R,9S)-megastigman-3-one-4,7-ene-9-ol-9-O-α-L-arabinofuranosyl-(1→6)-β-D-glucopyranoside(9),2R,3R-2,3-Dihydro-2-(4′-hydroxy-3′-methoxyphenyl)-3-(glucosyloxymethyl)-7-methoxy-benzofuran-5-propanol(dihydrodehydrodiconiferyl-alcohol-β-D-glucoside)(10),Thy-midine(11),和Deoxyuridine(12)。其中化合物1为一个降倍半萜类新化合物,其余化合物从该种中首次分离。Twelve compounds including a new norsesquiterpenoid were isolated from the ethanol extract of Euphorbia helioscopia by silica gel,sephadex LH-20 and RP-18 column chromatography.They were identified as helioscopin D(1),isofraxidin(2),swertiamarin(3),13-carboxyblumenol C(4),4,4′-dimethoxy-3′-hydroxy-7,9′,7′9-diepoxyligan-3-O-β-D-glucopyranoside(5),(+)-syringaresinol-4′-O-β-D-glucoside(6),2S,3R-2,3-dihydro-2-(4-hydroxy-3-methoxyphenyl)-3-hydroxymethyl-7-methoxybenzofuran-5-(trans) propen-1-ol-3-O-β-glucoside(7),ouinquenin L1(8),(6R,9S)-megastigman-3-one-4,7-ene-9-ol-9-O-α-L-arabinofuranosyl-(1→6)-β-D-glucopyranoside(9),2R,3R-2,3-dihydro-2-(4′-hydroxy-3′-methoxyphenyl)-3-(glucosyloxymethyl)-7-methoxy-benzofuran-5-propanol(dihydrodehydrodiconiferyl-alcohol-β-D-glucoside)(10),thymidine(11),and deoxyuridine(12) on the basis of NMR data and comparison with literatures.
