摘要: 以贵州野生甜藤干粉为原料,通过单因素试验,再通过正交试验优化甜藤多糖提取工艺,并采用Sevag法、TCA法、Sevag-TCA法、HClO4法进行脱蛋白方法研究。结果表明,甜藤多糖最优提取工艺为:以水为溶剂,料液比1:50,超声功率70 W,水浴温度70 ℃,超声提取时间110 min,提取2次;HClO4法脱蛋白效果最佳,经3次脱蛋白处理后蛋白脱出率为94.78%,多糖损失率为15.14%,该法用于脱除甜藤植物多糖中的蛋白质,工艺简单,成本低,具有一定应用价值。

Abstract: A process for extraction of polysaccharides from Guizhou wild Paederia scandens powder was optimized through single factor test and orthogonal test.Four different methods,namely Sevag,TCA,Sevag-TCA,and HClO4 methods,for the removal of protein were investigated.The results showed that HClO4 method was demonstrated to be the best way for the removal of protein,and a protein emergence rate of 94.78% can be achieved after deproteinizing protein for 3 times.Moreover,15.14% polysaccharide loss rate was detected under the optimal extraction conditions of using water as solvent,solid-liquid ratio of 1:50,and ultrasonic power of 70 W at a bath temperature of 70 ℃ within an extraction time of 110 min repeating for two times.This process was simple and low cost.
