仙人掌多糖提取与多糖胶囊的制备

本研究以仙人掌浓缩清汁为原料,进行仙人掌多糖提取的单因素及正交提取试验,并将提取的仙人掌多糖制备成多糖胶囊。正交提取试验结果表明,仙人掌汁浓缩5倍,乙醇与仙人掌汁的比例为1:3,醇析温度为-18℃时,仙人掌多糖的提取得率最高;仙人掌多糖胶囊制备方法:以95%乙醇作为仙人掌多糖的粘合剂制粒,6%～8%HPMC溶于60%乙醇中作包衣液,在35～40℃下包衣,干燥2h后装胶囊,可获得品质较好的仙人掌多糖胶囊。

Extracting Technique of Polysaccharide from Cactus and Making Technique of Capsule from Polysaccharide

Single factor test and orthogonal test were performed to extract polysaccharides from extract cactus juice, and the polysaccharides extracted were prepared to polysaccharides capsules. The experimental results showed that 5 times concen-trated cactus juice, a mixture of ethanol-cactus juice(1:3)and temperature of -18℃ were optimal for highest yield. The method of preparing polysaccharides capsules were as follows: 6 %～8 % HPMC were dissolved into 60% ethanol as coating fluid, coating at 35～40℃, filling the capsules after drying for 2h.
