In order to study the extraction process of selenium in Se-enriched Agrocybe cylindracea and anti-fatigue effect. The experiment determined the extraction process of Se in Se-enriched Agrocybe cylindracea by a single factor: extraction times was 2, extraction time was 7 h, lye solution was 0.075 mol/L, extraction temperature was 60℃, and a solid-to-solvent ratio was 1:20 (g/mL). Based on a single factor test using three factors and three levels of response surface analysis to determine the impact of each factor based process regression analysis to extract the resulting value for the selenium content of the response and the response surface contour map, to determine the optimum extraction conditions of Se in selenium Agrocybe cylindracea which the lye solution was 0.073 mol/L with a solid-to-solvent ratio was 1 : 24.9 (g/mL) for 6.91 h. The maximum predicted the selenium content under the optimized conditions was 22.82 μg/g. In addition, anti-fatigue effect of selenium solution were studied which showed the results:selenium could significantly improve the vitality of mice, enhanced its endurance, delayed time of feeling tired.
