Research Progress in Chemical Constituents and Pharmacological Effects of Chaenomeles Speciosa Nakai and Chaenomeles / 中国药师

The studies on the chemical compositions and pharmacological actions of Chaenomeles speciosa Nakai were systemized and compared with those of the other plants of Chaenomeles in this paper. The pharmacological effects of the fruit of Chaenomeles inclu-ding anti-tumor, anti-oxidation, anti-inflammation and analgesia, antibacterial, hypoglycemic and hypolipidemic action and so on were reviewed to provide scientific basis for the further studies and utilization of Chaenomeles.

Studies on chemical constituents of Chaenomeles speciosa (sweet) Nakai (II) / 第二军医大学学报

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.
