皱皮木瓜正丁醇部位化学成分研究

目的研究皱皮木瓜正丁醇部位的化学成分。方法利用正反相硅胶、凝胶(Sephadex LH-20)等多种柱色谱法对皱皮木瓜正丁醇部位化学成分进行分离纯化,并根据理化性质和波谱数据进行结构鉴定。结果分离得到了8个化合物,经鉴定分别为1,2,4-苯三酚(1)、没食子酸(2)、奎尼内酯(3)、5-羟基烟酸(4)、对羟基肉桂酸葡萄糖酯(5)、对羟基苯甲酸葡萄糖苷(6)、(6S,9R)-长寿花糖苷(7)、吐叶醇1-O-β-D-木糖-6-O-β-D-葡萄糖苷(8)。结论化合物1～6均为从本植物中首次分离得到。

The chemical Constituents in the n-butanol Extracts of Cheanomeles speciosa (Sweet) Nakai

Objective To investigate the chemical constituents in the n-butanol extracts of Chaenomeles speciosa. Methods Multi-chromatographic methods including Silicagel column chromatography and Sephadex LH-20 gel permeation were employed for the isolation and purification.The structures were identified on the basis of chemical evidence and spectral data. Results Eight compounds were isolated and identified as 1,2,4-Benzenetriol(1),gallic acid(2),epi——quinide(3),5-Hydroxynicotinic acid(4),p-coumaric acids glucosyl esters(5),p-hydroxybenzoic acid glucoside(6),(6S-9R)-roseoside(7),Vomifolioll-O-β-D-xylopyranosy-6-O-β-D-glucopyranoside(8). Conclusion Compounds 1～6 were obtained from this genus for the first time.
