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.
