摘　　要：目的:研究确定茶树菇多糖的最佳提取工艺。方法:采用热水浸提法对茶树菇多糖的提取工艺条件进行优化,以多糖得率为评价指标,选用单因素试验和L18(35)正交试验法,考察浸提比、pH值、浸提温度、乙醇浓度、浸提时间等5个因素对茶树菇多糖得率的影响。结果:提取茶树菇多糖的最佳工艺条件是浸提比1∶10、pH7.5、浸提温度90℃、浸提时间1 h、乙醇浓度95%,为改善茶树菇多糖的提取方法提供了实验基础。Objective： to study the optimum extracting Process of Agrocybe cylindracea polysaccharides. Methods： The technique conditions of Agrocybe cylindracea polysaccharides aere opeimized by the hot water extraction, determined the content of polysaccharides as the estimative targets and choosed the single-factor experiment and the orthogonal design of L18 （ 3^5 ） to investgate the polysaccharides content influenced by five factors such as water sample ratio, pH value, extraction temperature, ethanol concentration, the time of extraction. Results ： The optimum extraction conditions uere as follows ： water sample ratio 1： 10 ,pH7. 5 ,extaction temperature was 90℃, one hour every time,ethanol concentration was 95 %. made the experiment foundation for optimizing the extraction methods of Agrocybe cylindracea pelysaccharides.
