摘 要:采用溶剂提取、萃取粗分离、硅胶和Sephadex LH-20凝胶柱色谱以及制备HPLC等纯化技术,从采自北京郊区的尼泊尔菊三七栽培品中分离得到4个化合物,通过波谱分析并参考文献数据鉴定其结构分别为7S,8R-9'-O-乙基-去氢双松柏醇-9-乙酸酯(1)、9'-O-乙基-去氢双松柏醇(2)、去氢双松柏醇-9,9'-二乙酸酯(3)和(+)-梣皮树脂醇(4)。1为新的2,3-二氢苯并呋喃-8,3'-新木脂素型化合物,2~4均为首次从尼泊尔菊三七中分离得到的木脂素类化合物。对4个化合物在DMSO-d6溶剂中的^1H-和^13C-NMR数据进行了全归属。Taking application of some isolation and purification technologies,including solvent extraction,rude solvent isolation,column chromatographies on silica gel and Sephadex LH-20,and preparative HPLC,4 compounds were obtained from Gynuranepalensiscultivated in a suburban area of Beijing. Their structures were identified by spectroscopic methods in conjunction with comparison of the NMR data with literature values as 7S,8R-9'-O-ethyl-dehydrodiconiferyl-9-acetate( 1),9'-O-ethyl-dehydrodiconiferyl alcohol( 2),dehydrodiconiferyl-9,9'-diacetate( 3),and( +)-medioresinol( 4),respectively. 1 is a new 2,3-dihydrobenzofuran-8,3'-neolignane type compound,and 2-4 were isolated from G. nepalensis for the first time. The complete assignment of the ^1H-and ^13C-NMR spectroscopic data of the four compounds recorded in DMSO-d6 was achieved.
