摘要：Purification, characterization, in vitro antioxidant and antitumour activities of polysaccharides from apple peel pomace obtained by pre-pressing paration were investigated. Apple peel polysaccharides (APP) were obtained by water
extraction and ethanol precipitation. They were further purified by chromatography of Cellulo DEAE-学生怎么读
52 and Sephadex G-150 to obtain three fractions (APP-1, APP-2 and APP-3). Both GC-MS and HPLC analysis showed that galacto and arabino
were two main components in the three fractions with an average molecular weight of 197 kDa, 395 kDa and 303 kDa, respectively. Uronic acids were only prented in APP-2 and APP-3, which were further confirmed by Fourier transform infrared宝宝出牙
spectroscopy. Besides, the results showed that the antioxidant activity measured by ferric-reducing power and scavenging of O2,
