目的:研究甘松根茎的化学成分。方法:运用大孔树脂Diaion HP-20、硅胶、反相ODS、Sephadex LH-20等柱色谱方法,结合制备型HPLC进行分离纯化,根据理化性质和MS、NMR等波谱学数据进行结构鉴定。结果:从甘松根茎中分离鉴定了6个化合物,分别为:8-羟基松脂醇-4-O-β-D-吡喃葡萄糖苷(1)、8-羟基松脂醇-4’-O-β-D-吡喃葡萄糖苷(2)、8-羟基松脂醇-4-O-(β-D-吡喃葡萄糖基)-4’-O-β-D-吡喃葡萄糖苷(3)、环橄榄脂素-6-O-β-D-吡喃葡萄糖苷(4)、阿魏酸(5)、绿原酸甲酯(6)。结论:化合物1～6均为首次从该属植物中分离得到。
Objective: To study the chemical composition of Rhizome of Brassica. METHODS: The constituents were isolated and purified by column chromatography on macroporous resin Diaion HP-20, silica gel, reverse phase ODS, Sephadex LH-20 and preparative HPLC. The structures were elucidated on the basis of physicochemical properties and MS, NMR and other spectroscopic data. Results: Six compounds were isolated and identified from the roots of Brassica napus, which were 8-hydroxynol-4-O-β-D-glucopyranoside (1) glucopyranoside (2), 8-hydroxynol-4-O- (β-D-glucopyranosyl) -4’-O-β-D-glucopyranoside (3) Cycloalhodostatin-6-O-β-D-glucopyranoside (4), Ferulic acid (5), Methyl chlorocarbonate (6). Conclusion: Compounds 1 ~ 6 were isolated from this genus for the first time.
