Phenolic profiles and antioxidant activities of exocarp, endocarp, and hypanthium of three pear cultivars grown in China

The phenolic composition of the exocarp, hypanthium, and endocarp from three pear cultivars: Jingbai, Korla Crystal were measured by high-performance liquid chromatography method with diode array detection (HPLC-DAD), while antioxidant activities investigated using DPPH radical andABTS cation scavenging activity, FRAP. Ferulic acid, chlorogenic caffeic acid detected as major components. exocarp Jingbai had a relatively high content (0.691 mg kg-1) hypanthium varieties. highest ferulic rutin content. presented total flavonoid contents in terms ABTS value, 83.62 ± 0.08%. 87.30 0.03%. Positive correlations among TPC, TFC, results reveal that different parts Pyrus communis L. have effective activity for pharmaceutical application.
