【摘要】 采用超声波法提取杏鲍菇(Pleurotus eryngii)粗多糖,通过单因素和正交试验确定提取的最佳条件为超声波功率70 W、时间40 min、料液比1∶40(w/v),粗提物中的多糖量为71.2 mg/g;对杏鲍菇粗多糖保湿性能初步研究表明:1%杏鲍菇粗多糖在6 h内保湿性能优于5%甘油。

【Abstract】 Single parameter and orthogonal tests were used to determine the optimal conditions for extracting polysaccharide from Pleurotus eryngii fruit bodies using ultrasound.Crude extracts containing the highest concentration of polysaccharide(71.2 mg/g) were obtained when P.eryngii fruit bodies were suspended in water at a ratio of 1∶40 and exposed to 70 W of ultrasonic power for 40 minutes.The moisturizing effect of 1%(w/v) P.eryngii crude polysaccharide was higher compared with 5%(v/v)glycerine or deionized water over a 6 h period.
