微波辅助提取银杏叶多糖工艺及其体外抗氧化活性研究OA北大核心CSCDCSTPCD
Optimization of Microwave-assisted Extraction Process for Polysaccharides from Ginggo biloba Leaves and Anti-oxidant Activity in Vitro
以水作为提取溶剂、银杏叶多糖提取率为指标,采用微波辅助提取法,在单因素试验的基础上,通过正交试验对银杏叶多糖的微波辅助提取工艺进行优化,并采用清除DPPH自由基、.OH和O2.模型对其体外抗氧化活性进行评价,并与VC进行比较。结果表明：微波辅助提取银杏叶多糖的最佳出工艺条件为微波功率480W、液料比30：1（mL/g）、提取时间8min、提取2次,多糖得率为14.70%。银杏叶多糖具有较强的清除DPPH自由基、.OH的能力,并与质量浓度呈一定正相…查看全部>>
Orthogonal array design method was applied to optimize the microwave-assisted water extraction of polysaccharides from Ginggo biloba leaves（GBLP） in order to maximize polysaccharide yield.Meanwhile,the antioxidant activity in vitro of polysaccharides from Ginggo biloba leaves was assessed by DPPH,hydroxyl and superoxide anion free radical scavenging assays and compared with vitamin C.The results showed that the optimal extraction conditions were microwave po…查看全部>>
