超微粉碎云芝子实体对云芝多糖提取的影响

Influence of Super Fine Crushing on the Extraction of Polysaccharides from Polystictus Versicolor

目的:探讨超微粉碎云芝子实体的云芝多糖提取工艺条件。方法:采用超微粉碎技术对云芝进行预处理,所得微粉(5 μm)与云芝子实体进行多糖提取的对比试验,然后对云芝微粉提取多糖进行正交实验,优化提取工艺。结果:云芝微粉的多糖提取收率比云芝子实体的多糖得率平均高出61%,云芝超微粉碎处理后最优提取工艺为:100℃,80 min,提取3次。结论:超微粉碎有利于云芝多糖的提取。

Objective： To study the extractive technique of Polysaccharides from Polystictus Versicolor pretreated by super fine erushing. Methods： Polystictus versieolor was pretreated by technique of super fine crushing, and the contrast examination of super powder（5μm）and polystictus versicolor was done. Then the extractive technique of polysaccharides from polystictus versicolor super powder was optimized by the orthogonal design. Results ： The extraction yield of Polysaccharides from polystictus versicolor super powder was higher 61% than that of polystictus versicolor. The optimum extractive technique of polysaccharides was 100℃ , 80 rain and extracting 3 times. Conclusion ： Technique of super fine crushing is propitious to the extraction of polysaccharides from polystictus versicolor.
