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 L1, (35 ) 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 degrees C , one hour every time,ethanol concentration was 95%. made the experiment foundation for optimizing the extraction methods of Agrocybe cylindracea polysaccharides.
