| Abstract: | Two new quinic acid derivatives (1, 2), together containing eighteen (3–20) known compounds, were isolated from the fruits of Chaenomeles speciosa. Spectroscopic methods and previous data retrieved from the literature were used to determine the chemical structures of the compounds. Among the compounds, quinic acid derivatives (3, 4, 6, 7), phenolic acid compounds (8, 10, 11) and catechin derivatives (18, 19, 20) were isolated for the first time from the family Chaenomeles. The chemotaxonomic significance of the compounds was also discussed. |
