摘要
优化提取工艺条件,从牡蛎中提取具有调节机体免疫、抑制肿瘤、延缓衰老、降血糖、血脂、等生物活性的多糖。采用硫酸-苯酚法测定牡蛎多糖,根据L9(34)正交试验对牡蛎多糖(Polysaccharide of Oyster)的提取条件进行优化,确定水提取多糖的工艺参数为:pH为6、提取时间5 h、提取次数为3次、水浴温度为75℃,该条件下多糖得率达2.56%。
The author made a study on the optimum preparation procedure for extraction of polysaccharide from the Oyster through sulfate-phenol method, the orthogonal test obtain the extracting technology of oyster. The optimal technical was 5 hours, extraction 3 times and extraction temperature was 7 of four factors and three levels were studied to conditions were： the pH was 6, extraction time 5 ℃, extracting ratio was 2.56 %.
