摘要
目的研究黑刺菝葜茎的化学成分,为充分利用黑剌菝葜药用植物资源鉴定基础。方法利用大孔树脂、硅胶和sephadex LH-20等色谱分离手段进行分离纯化,通过理化性质和光谱分析鉴定结构,结果从黑刺菝葜茎乙醇提取物的乙酸乙酯、正丁醇萃取物分离鉴定了5个化合物,分别为反式白藜芦醇(1)、槲皮素-3-O-β-D-葡萄糖苷(2)、木犀草素-7-O-β-D-葡萄糖苷(3)、拉克索皂苷元-3-O-[α-L-吡喃阿拉伯糖基-(1→6)]-β-D-吡喃葡萄糖苷(4)、拉克索皂苷元-3-O-[β-D-吡喃葡萄糖基-(1→4)][α-L-吡喃阿拉伯糖篡.(1→6)]-β-D-吡喃葡萄糖苷(5)。结论化合物1—3首次从本植物中分离得到。
OBJECTIVE To isolate and elucidate the chemical constituents from the stem of Smilax scobinicaulis C. H. Wright. METHODS Column chromatography csilica gel, macroporous resin, and sephadex LH - 20 were used to isolate the constituents. Their structures were elucidated by physical and spectral data. RESULT Five compounds are isolated and their structures were identified as trans-resveratrol ( 1 ), quercetin-3- O-β-D-glucopyranoside(2), luteolin-7- O-β-D-glucopyranoside (3), laxogenin-3- O- [ α-L-arabinopyranosy 1- (1→6) ]-β-D- glucopyranoside (4), laogenin-3-O- [ β-D-glucopyrnosyl- ( 1→4)- 0- [ α-L-arabinopyranosyl- (1→6) ]-β-D-glucopyranoside(5). CONCLUSION Compound 1 - 3 are isolated from this plant for the first time.
