齿叶白鹃梅叶中黄酮类成分的分离与结构鉴定

目的研究齿叶白鹃梅叶的化学成分。方法采用硅胶柱色谱、重结晶和Sephadex LH-20凝胶柱色谱的方法进行化学成分的分离和纯化,根据化合物的理化性质和波谱数据鉴定其结构。结果分离得到6个黄酮类化合物,经鉴定为芹菜素(apigenin1,),木犀草素(luteolin,2),槲皮素(querce-tin,3),槲皮素-3-O-β-D-葡萄糖苷(quercetin-3-O-β-D-glucopyranoside,4),芹菜素-7-O-β-D-葡萄糖苷(apigenin-7-O-β-D-glucopyranoside,5),芹菜素-7-O-β-D-新橙皮糖苷(apigenin-7-O-β-D-neosphero-side,6)。结论化合物1-6均首次从此植物中分离得到。

Chemical constituents of the leaves of Exochorda serratifolia S.Moore

Objective To study the chemical constituents of the leaves of Exochorda serratifolia S.Moore. Methods Isolation and purification were carried out on the chromatography of silica gel and Sephadex LH-20. Their structures were elucidated on basis of physicochemical properties and spectral data. Result Six compounds were isolated and identified as apigenin（1 ）, luteolin（ 2 ）, quercetin（ 3）, quercetin-3-O-β-D-glucopyranoside（ 4）, apigenin-7-O-β-D- glucopyranoside（5 ） and apigenin-7-O-β-D-neospheroside（6）. Conclusion Compounds 1-6 are isolated from this plant for the first time.
