摘要
目的:对构树Broussonetia papyrifera(L.)Vent.叶的化学成分进行分离和鉴定。方法:采用硅胶柱层析、sephadex LH-20柱层析和重结晶等方法分离纯化,根据理化性质和光谱鉴定化合物的结构。结果:从构树叶乙酸乙酯部位分离得到11个化合物,分别为:芹菜素(apigenin,1)、大波斯菊苷(cosmosiin,2)、牡荆苷(vitexin,3)、木犀草素(luteolin,4)、木犀草素-7—O-β-D-葡萄糖苷(luteolin-7—O-β-D—glucopyranoside,5)、7-甲氧基香豆素(7-methoxycoumarin,6)、东莨菪素(scopoletin,7)、三十一烷醇(l-hentriacontanol,8)、槲皮素(quercetin,9)、7-甲氧基芹菜素(7-methoxyapigenin,10)、β胡萝卜苷(daucosterol,11)。结论:化合物1—8首次从构树中分离得到。
AIM: To study the chemical constituents of leaves of Broussonetia papyrifera. METHODS: The chemical components were isolated and purified by silica gel column and Sephadex LH-20 as well as recrystallization. The chemical structures were elucidated on the basis of physico-chemical properties and spectral data. RESULTS: Eleven compounds were isolated and identified as apigenin(1), cosmosiin ( 2 ), vitexin ( 3 ), luteolin ( 4 ), luteolin-7- O-β-D-glucopyranoside ( 5 ), 7-methoxycoumarin ( 6 ), scopoletin ( 7 ), 1- hentriacontanol(8), quereetin(9 ), 7-methoxyapigenin (10) and daucosterol (11). CONCLUSION: Compounds 1 ~ 8 have been obtained from the plant for the first time.
