摘要: 对河蚬多糖的提取工艺及其免疫活性进行了研究。以响应面设计优化提取工艺,得到最佳的工艺条件为固液比1∶30,提取时间102 min,提取温度为91 ℃,试验所得河蚬多糖提取率为平均为9.71%。试验小鼠分为空白对照组、河蚬多糖低、中、高剂量组(50、100、200 mg/kg·d),河蚬多糖以灌胃方式饲喂小鼠,结果表明河蚬多糖能增强巨噬细胞吞噬能力,且与对照组相比碳廓清指数和小鼠的脏器指数显著增加,说明河蚬多糖能促进小鼠的免疫能力,显著提高机体的特异性免疫和非特异性免疫能力。

Abstract: The extraction process and immune function of Corbicula fluminea polysaccharides were studied.Response surface methodology was employed to optimize the extraction process.The results of optimum extraction conditions were as follows:ratio of raw material to solvent 1∶30 ( g/mL ) ,extraction time 102 min and extraction temperature 91 ℃ ,and under these conditions,the average extraction yield was 9.71%.The effect of Corbicula fluminea polysaccharides on the immune function of normal mice was studied.Corbicula fluminea polysaccharides were prepared by the method of water extraction and alcohol precipitation.The mice were divided into blank control group and Corbicula fluminea polysaccharides groups with the dose of 50,100,200 mg/kg·d,respectively.Organ index,macrophage phagocytosis of chicken red blood cells,carbon particle clearance index,organ and body weight ratio,delayed type hypersensitivity reaction(DTH) were analyzed.The results showed that compared with the blank control group,carbon particle clearance index,organ and body weight ratio were increased significantly,and Corbicula fluminea polysaccharides had enhanced mononuclear macrophage function.Conclusion:Corbicula fluminea polysaccharides can enhance mouse immunocompetence and improve the specificity and non-specificity immune function.

Key words: Corbicula fluminea polysaccharides, response surface methodology, process optimization, immunological activity
