摘要：
Apple pomace from juice processing was investigated as a potential source of fine chemicals. Major compounds isolated and identified include epicatechin, caffeic acid, phloretin-2'-glucoside (phloridzin), phloretin-2'-xyloglucoside, 3-hydroxyphloridzin, quercetin-3-arabinoside (avicularin), quercetin-3-xyloside (reynoutrin), quercetin-3-galactoside (hyperin), quercetin-3-glucoside (isoquercitrin) and quercetin-3-rhamnoside (quercitrin). The isolation of 3-hydroxyphloridzin as a natural component in apple was novel and its chemical structure, as well as those of the other co-occurring polyphenols, were established by H-1 and C-13 NMR spectroscopy and by acid hydrolysis.
