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。 Four compounds were isolated from the cultivated Neisseria notoginseng collected from the suburbs of Beijing using solvent extraction, crude extraction, silica gel, Sephadex LH-20 and preparative HPLC. Spectral analysis and reference Their structures were identified as 7S, 8R-9’-O-ethyl-dehydroacenitrone 9-acetate (1), 9’-O-ethyl- Dehydrogenated coniferin-9,9’-diacetate (3) and (+) - ecchymoside (4). 1 is a novel 2,3-dihydrobenzofuran-8,3’-neolignan compound, and 2 to 4 are lignan compounds isolated from N. chrysanthemum for the first time. The 1H- and 13C-NMR data for the four compounds in DMSO-d6 solvent are fully assigned.
