目的建立阿里红多糖的最佳提取工艺。方法采用水提醇沉法,以总多糖提取率为指标,对阿里红中多糖提取工艺进行系统研究。选择提取时间、浸提料液比、和浸提次数三因素。通过正交实验L9(33)确定阿里红多糖的最佳提取工艺条件。结果最佳工艺条件为浸提时间2h,料液比1∶12,浸提次数3次。结论该工艺简便、合理,为从药材或制剂中提取阿里红多糖提供了参考。
Objective To establish the best extraction technology of polysaccharides of Alitake. Methods The method of water extraction and alcohol precipitation was adopted, and the extraction rate of total polysaccharides was used as an index to systematically study the extraction technology of polysaccharides in Alizarin red. Select the extraction time, the ratio of liquid to extract, and the number of leaching three factors. The orthogonal experiment L9 (33) was used to determine the optimal extraction conditions of Alhumoderma polysaccharides. Results The optimum conditions for the extraction time 2h, the ratio of solid to liquid 1:12, leaching times 3 times. Conclusion The process is simple and reasonable, which provides a reference for the extraction of Alhistic polysaccharides from medicinal materials or preparations.
