楮叶中香豆素和黄酮类化学成分研究

摘要

To study the antiftmgal constituents in the leaves of Broussonetia paFyrifera( L. ) Vent. ,chromatographic and NMR spectroscopic techniques were used to isolate and elucidate the constituents. Ten compounds were isolated and i-dentified as umbelliferone ( 1 ), esculetin(2), apigenin(3), luteolin (4), kaempferol (5), vitexin (6), apigenin-7-O-β-D-glucuronide (7), genkwanin (8), quercetin (9) , and dihydroquercetin (10). Compounds 1-7 were isolated from this plant for the first time.%本文对楮树(Broussonetia papyrifera(L.)Vent.)叶中的香豆素和黄酮类成分进行研究,利用柱层析、重结晶、色谱技术等分离手段,分离得到了10个化合物,经理化性质和波谱数据分析鉴定为伞形花内酯(1)、七叶内酯(2)、芹菜素(3)、木犀草素(4)、山柰酚(5)、牡荆素(6)、芹菜素-7-O-β-D-葡萄糖醛酸(7)、芫花素(8)、槲皮素(9)、二氢槲皮素(10).化合物1～7均为首次从该植物中分离得到.
