| 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. |
