摘 要:目的:研究杜仲化学成分。方法:将杜仲树皮粉碎后,用95%乙醇提取,取其乙酸乙酯部位采用Silica gel、Sephadex LH-20和ODS C18色谱等色谱方法进行分离,并采用波谱学方法鉴定化学物结构。结果:从乙酸乙酯部位分离得到8个化学成分,分别鉴定为:环橄榄树脂素(1)、(7R,8S,8'R)-4,9,4',8'-四羟基-3,3'-二甲氧基-7,9'-单环氧木脂素(2)、erythro-guaiacyl-glycerol-β-coniferyl aldehyde ether(3)、松脂素(4)、8-羟基松脂素(5)、C-veratroylglycol(6)、β-羟基-3-甲氧基-4-羟基苯乙酮(7)、3-hydroxy-4-methoxycinnamaladehyde(8)。结论:其中,化合物5-8为首次从该植物中分离得到,化合物1-5为木脂素类化合物,化合物6-8为苯丙素类化合物。Objective: To investigate the chemical constituents from the barks of Eucommia ulmoides. Methods: After the reflux extraction of the barks of Eucommia ulmoides with 95% ethanol,and the ethyl acetate part was separated and purified by chromatographic methods,such as silica gel,Sephadex LH-20,ODS C18. The structures of isolated compounds were elucidated with modern spectral methods. Results: Five lignanoids and three phenylpropanoids were isolated from Eucommia ulmoieds,which confirmed as cycloolivil( 1),( 7R,8S,8'R)-4,9,4',8'-tetrahydroxy-3,3'-dimethyoxyl-7,9'-monoepoxy lignan( 2),erythro-guaiacyl-glycerol-β-coniferyl aldehyde ether( 3),pinonesinol( 4),8-hydroxypinoresinol( 5),C-veratroylglycol( 6),β-hydroxypropiovanllone( 7) and 3-hydroxy-4-methoxycinnamaladehyde( 8). Conclusion: Compounds 5 - 8 are isolated from this plant for the first time.
