摘　　要：目的:茶树菇多糖是一种重要的生物活性物质,具有抗病毒、抗肿瘤和增强人体免疫力等多种功能,在保健食品及药品开发等方面具有广泛的应用前景。本文主要优化茶树菇多糖提取的工艺条件。方法:通过单因素分析和响应面试验设计,以茶树菇多糖含量为指标,考察pH、时间、温度和料液比4个因素对其提取的影响。结果:茶树菇多糖提取的最佳工艺条件为:pH 4.98,温度80.98℃,提取时间3.88 h,料液比1∶15.98。在该条件下茶树菇多糖的最大提取率为22.12%。结论:本研究结果为茶树菇多糖的提取及其应用奠定了良好基础。Objective： the polysaccharide from Agrocybe c？lindracea is an important bioactive substance with antivirus, anti-tumor, enhancing immunity and other functions, and has broad application prospects in heahhcare food and drug preparation. This paper mainly studied the extraction process. Methods： the single factor test and the response surface were used to optimize the extracting conditions. Targeted as the yield of Agrocybe cylindracea polysaccharide, four factors： pH, extraction time, extraction temperature and raw material to water were studied by response surface analysis. Results： the results were as follows： pH 4.98, extraction time 3.88 h, extraction temperature 80.98 ℃ and raw material to water 1：15.98. The maximum polysaccharide yield was 22.12% under the above conditions. Conclusion： This study lays a good basis for the extraction and future industrial use of Agrocybe cylindracea polysaccharide.
