Antioxidant, Ferric Iron Chelation and Antimicrobial Activities of Extracts of Pseudocydonia sinensis (Chinese Quince) Fruit

There are accumulated lines of evidence on the importance of plants as natural sources of medicinal agents since most synthetic antioxidants and antibiotics have been implicated in cytotoxicity and microbial resistance. However, biological activities of phytochemicals are partly dependent on extraction solvents. In this study, the antioxidant, ferric ion chelation and antimicrobial activities of the fruit extracts of Pseudocydonia sinensis (Chinese quince) were examined. The methanol, aqueous and ethanol extract recorded highest antioxidant, ferric ion chelation and antimicrobial activities, respectively. The ethanol and methanol extracts showed significant antimicrobial activities against all microbes employed in this study. The fruit extract may therefore be a promising source of antioxidant and antimicrobial agents of natural origin.
