【摘要】 目的:优选酸法提取鱼腥草多糖最佳工艺。方法:以多糖得率、多糖含量为指标成分,采用正交试验对酸法提取鱼腥草多糖的工艺进行优选。结果:优化工艺为:60℃,PH=3、温浸3次,每次3h。多糖得率及含量分别为18.30%,15.00%。结论:该工艺合理,多糖成分提取完全。更多还原

【Abstract】 Objective: To establish the optimum preparative procedure of polysaccharide from Houttuynia cordata with acid solution.Methods: The optimum conditions of extraction process of polysaccharide from Houttuynia cordata was selected with the yield and polysaccharides content as mark by orthogonal experimental design. Results: The optimum preparative procedure was as follow: The Houttuynia cordata was extracted at temperature of 60℃, 3 times, 3 hours per time and with acid solution of PH 3. The polysaccharides yield and content were 18.30%,15.00%. Conclusion: The optimum preparative procedure is simple, quickly and high efficient.更多还原
