摘  要:
对中药薤白中可溶性粗多糖的提取工艺进行了研究。结果显示,影响多糖提取率因素的主次顺序为温度>提取时间>料液比。最佳提取工艺为提取温度90℃、料液比1∶12、提取时间90 min,薤白多糖的提取率为13.93%。同时研究了提取过程中脱蛋白的处理方法,结果显示,木瓜蛋白酶+Sevag法脱蛋白处理效果最佳。

摘  要:
The extraction of polysaccharide from Allium macrosttemon B.was studied.With single factor test and orthogonal experiment design method we analyzed the influence of factors such as temperature(A),solid-liquid ratio(B) and time(C) on the extraction percent of the polysaccharides.The results indicated that the influence of the three factors on extraction percent of the polysaccharides was A>C>B and the temperature was the main factor.The optimum extraction technology was A_3B_2C_3(temperature was 90?℃,solid-liquid ratio was 1∶12 and the extraction time was 90 min).Under these conditions,the extraction percent of soluble polysaccharides from Alluim macrosttemon B.was 13.93%.In addition,the method of removing protein was studied and the results indicated that Sevag method combined with the enzyme was best.
