摘要：

Objective To investigate the chemical constituents in the barks of Ailanthus altissima.Methods The chemical consituents were isolated by silica gel,Sephadex LH-20,ODS,as well as RP-HPLC column chromatographies.Their structures were identified on the basis of physicochemical properties and spectral analysis.Results Twelve compounds were isolated and idenified as erythro-guaiacylglycerol-β-O-4′-coniferyl ether(1),threo-guaiacylglycerol-β-O-4′-sinapyl ether(2),threo-guaiacylglycerol-β-O-4′dihydroconiferyl ether(3),caffeic acid methyl ester(4),coniferin(5),scopoletin(6),7-methoxy-2H-chromene(7),vanillin(8),4-hydroxy-2(E)-nonenoic acid(9),(9S,12S,13S)-(E)-9,12,13-trihydroxy-10-octadecaenoic acid(10),β-sitosterol(11),and daucosterol(12),respectively.Conclusion Compounds 1—5,7,9,and 10 are isolated from this plant for the first time.
