摘要:
目的:研究皱皮木瓜的化学成分。方法:利用多种色谱法对皱皮木瓜的化学成分进行系统研究,并根据理化性质和波谱数据进行结构鉴定。结果:从皱皮木瓜的乙酸乙酯萃取部位分离鉴定了9种化合物,分别为绿原酸甲酯(Ⅰ),5-O-咖啡酰基-奎宁酸丁酯(Ⅱ),奎宁酸丁酯(Ⅲ),5-羟甲基-2-糠醛(Ⅳ),三十烷酸(Ⅴ),(-)-表儿茶素(Ⅵ),7,8-二羟基香豆素(Ⅶ),3,4-二羟基苯甲酸乙酯(Ⅷ),原儿茶酸(Ⅸ)。结论:化合物Ⅲ~Ⅷ均为从本属植物中首次分离得到。

Abstract:
Objective:To investigate the chemical constituents of Chaenomeles speciosa.Methods: The chemical constituents of Chaenomeles speciosa was analyzed by various chromatographic methods.The structures of the compounds were identified based on physicochemical properties and spectral data.Results: Nine compounds were obtained from the ethyl acetate fraction of C.speciosa and were identified as methyl chlorogenate (Ⅰ),5-O-cafeoyl quinic acid butyl ester (Ⅱ),quinic acid butyl ester (Ⅲ),5-hydroxymethyl-furan-2-carbaldehyde (Ⅳ),triacontanoic acid (Ⅴ),(-)-epicatichin (Ⅵ),7,8-dihydroxy-coumanrin (Ⅶ),protocatechuic acid ethyl ester (Ⅷ),and protocatechuic acid (Ⅸ).Conclusion: Compounds Ⅲ-Ⅷ have been obtained from this genus for the first time.
