摘要
Eight phenolic compounds were isolated from the EtOAc-soluble acidic layer of methanol extracts of Asian pear (Pyrus pyrifolia Nakai cv. Chuhwangbae) fruit peels. These isolated compounds were identified to be arbutin (1), 4-(O-beta-d-glucopyranosyl)-3-(3'-methyl-2'-butenyl)benzoic acid (2, malaxinic acid), 3,4-dihydroxybenzoic acid (3), trans-chlorogenic acid (4), cis-chlorogenic acid (5), isorhamnetin 3-O-beta-d-glucopyranoside (6), 3,5-dicaffeoylquinic acid (7), and (-)-epicatechin (8) based on electronic spray ionization (ESI)-MS and NMR spectroscopic data. Of the isolated compounds, 2 and 5 were identified in pear for the first time.
