脱除蛋白质是真菌多糖纯化过程中较为重要的环节之一,为了优化裂盖马鞍菌多糖脱蛋白质工艺,采用Sevag法和三氯乙酸法对其多糖进行蛋白质脱除,通过比较2种方法处理后的蛋白质脱除率和多糖损失率来确定最佳的脱蛋白质方法。结果表明,三氯乙酸法脱除蛋白质效果最佳,其最佳工艺为三氯乙酸质量浓度50 g/L、三氯乙酸与粗多糖体积比1∶1、振荡时间40 min、静置时间40 min ,在此条件下蛋白质脱除率为92.37%,多糖损失率为16.91%。
脫除蛋白質是真菌多糖純化過程中較為重要的環節之一,為瞭優化裂蓋馬鞍菌多糖脫蛋白質工藝,採用Sevag法和三氯乙痠法對其多糖進行蛋白質脫除,通過比較2種方法處理後的蛋白質脫除率和多糖損失率來確定最佳的脫蛋白質方法。結果錶明,三氯乙痠法脫除蛋白質效果最佳,其最佳工藝為三氯乙痠質量濃度50 g/L、三氯乙痠與粗多糖體積比1∶1、振盪時間40 min、靜置時間40 min ,在此條件下蛋白質脫除率為92.37%,多糖損失率為16.91%。

Deproteinization is one of the most important steps in the purification process of fungi polysaccharide .In order to improve purification efficiency of polysaccharide ,the optimization of deproteinization process of crude polysaccharide from Helvella leucopus Pers .was carried out using Sevag reagent and trichloroacetic acid with protein removal rate and sugar loss rate as in-dexs .The results showed that trichloroacetic acid was more suitable to remove the protein from the crude polysaccharide ,and the optimum trichloroacetic acid concentration was 50 g/L ,the vo-lume ratio of trichloroacetic acid to crude polysaccharide was 1∶1 ,vibrating time and standing time were both 40 min .Under this condition ,the protein removal rate was 92 .37% ,and sugar loss rate w as 16 .91% .
