摘 要:采用硅胶、反相RP.18、SephadexLH-20凝胶和制备HPLC色谱技术对瑞香狼毒(StellerachamaejasmeL.)根的化学成分进行分离和纯化。通过核磁、质谱等方法鉴定了其中18个化合物:去甲络石苷元(1),异落叶松脂素(2),(+)-开环异落叶松树脂酚(3),豆甾4.烯-3,6-二酮(4),rel-(-)-(3R,3’R,4R,4’R)-6,6'-dimethoxy-[3,3'-blchroman]-4,4'-diol(5),methyl3-(2-hydroxy-4-((7-hydmxy-6-methoxy-2-oxo-2H—ehromen-3-y1)oxy)phen-y1)pmpanoate(6),狼毒素A(7),异狼毒素B(8),狼毒素B(9),雁皮素A(10),异雁皮素A(11),狼毒色原酮(12),mohsenone(13),丁香酸(14),二氢瑞香素乙(15),西瑞香索(16),β-谷甾醇(17),3,4,5-三甲氧基苯甲酸(18)。其中化合物1—6均为首次从该植物中分离得到。Eighteen compounds were isolated from the roots of Stellera chamaejasme L. using silica gel, reverse phase C18 silica gel, Sephadex L H-20 and HPLC. Spectral methods as MS, 1H NMR, 13C NMR and 2D NMR were used for struc- tttral identification. The structures were elucidated as ( + ) -nortrachelogenin ( 1 ), ( + ) -isolariciresinol ( 2 ), ( + ) -see- oisolariciresinol (3), stigmast-4-ene-3,6-dione (4), rel-(-) -( 3R, 3 'R, 4R ,4'R ) -6,6'-dimethoxy- [ 3,3 '-bichroman ] -4, 4'-dio1(5) ,methy 3-(2-hyd^oxy-4-(7-hydroxy-6-methoxy-2-oxo-2H-chromen-3-yloxy) phenyl) propanoate(6) ,ehamae- jasmenin A (7) , isochamaejasmenin B (8) , chamaejasmenin B ( 9 ) , sikokianin A ( 10 ) , isosikokianin A ( 11 ), chamaec- romone ( 12 ), mohsenone ( 13 ), syringic acid (14) , dihydrodeLphnodorin B ( 15 ), daphnoretin ( 16 ) ,β-sitostero ( 17 ), 3, 4,5-trimethoxfl benzoicaeid(18). Of these compounds, compounds 1 ~ 6 were firstly isolated from the species.
