目的对三七(Panax notoginseng(Burk.)F.H.Chen)花蕾的化学成分进行研究。方法利用体积分数为75%提取、D101大孔吸附树脂柱、硅胶柱、Sephadex LH-20柱色谱等方法分离纯化,根据理化性质和光谱数据确定化合物的结构。结果分离得到6个化合物,分别鉴定为:山奈酚-3-O-β-D-半乳糖(2→1)葡萄糖苷(kaempferol 3-O-(2″-β-D-galactopyranosyl)-β-D-glucopyranoside,1)、槲皮素-3-O-β-D-半乳糖(2→1)葡萄糖苷(quercetin3-O-(2″-β-D-galactopyranosy l)-β-D-g lucopyranoside,2)、鸟嘌呤核苷(guanosine,3)、腺嘌呤核苷(adenosine,4)、β-谷甾醇(-βsitostero l,5)、胡萝卜苷(daucostero l,6)。结论化合物1、2为首次从该植物花蕾中分离得到,化合物3、4为首次从该植物中分离得到。
Objective To study the chemical constituents of flower buds of Panax notoginseng (Burk.) F.H.Chen. Methods The compounds were isolated and purified by 75% volume fractionation, D101 macroporous resin column, silica gel column and Sephadex LH-20 column chromatography. The structures of the compounds were determined by physico-chemical properties and spectral data. Results Six compounds were isolated and identified as kaempferol 3-O- (2 “-β-D-galactopyranosyl) -β-D-glucosidase D-glucopyranoside, 1), quercetin 3-O- (2 ”-β-D-galactopyranosy 1) -β-Dg lucopyranoside, 2), guanosine (3), adenosine (4), β-sitosterol (5) and daucosterol (6). Conclusion Compounds 1 and 2 were isolated from the plant bud for the first time. Compounds 3 and 4 were isolated from this plant for the first time.
