摘要:通过从菠萝皮渣中提取菠萝粗多糖,探讨菠萝粗多糖的体外抗氧化功能。采用热水浸提法提取
菠萝多糖,用羟自由基体系、超氧阴离子体系、多糖的还原能力体系研究菠萝多糖清除自由基的能力。
结果表明,用水杨酸比色法测定菠萝多糖去除羟自由基能力,当浓度为12 mg/mL时,对羟自由基的清除
能力达90%以上。用邻***法测定菠萝多糖清除超氧阴离子的能力,当浓度为6 mg/mL时,超氧阴离
子的清除能力达80%以上。菠萝多糖还原能力与浓度呈良好的量效关系。

Pineapple haride was extracted from pineapple peel to discuss the antioxidant function of
Abstract:
haride pineapple in vitro. Hot water extraction was used to extract haride pineapple. The
ability of pineapple haride to scavenge free radicals was studied by using hydroxyl radicals system,
superoxide anion system and haride reductive ability system. Results showed that, using salicylic acid
colorimetry to determine the ability of pineapple haride to scavenge hydroxyl radicals, when the
concentration was 12 mg/mL, the scavenge rate reached 90%. While using pyrogallol autoxidation method to
determine t
