摘　　要：通过采用3,5-二硝基水杨酸法、蒽酮-硫酸法和苯酚-硫酸法测定大孢虫花PaecilomycestenuipesPeck菌丝体多糖含量,比较精密度、样品回收率、稳定性三个指标,得出最佳测定方法为蒽酮-硫酸法。根据一次一因素实验和Box-Behnken中心组合实验,应用SAS软件分析得出大孢虫花菌丝体多糖提取的最佳条件为:100℃沸水浴,提取2h,重复4次,料液比(菌丝体质量:蒸馏水体积)为1︰20,此条件下大孢虫花菌丝体多糖为4.12g/100g。The polysaccharide content of Paecilomyces tenuipes mycelia was detected by anthrone-sulfuric acid method. One-factor-at-a-time method, Box-Behnken central composite design and SAS software were adopted to investigate the effects of different extraction methods on polysaccharide content of Paecilomyces tenuipes mycelia. The optimal condition of polysaccharide extraction was： water bath treatment（100℃ ） for two hours and four times replication, and weight of mycelium/volume of distilled water =1：20. Under optimal condition, the polysaccharide content of Paecilomyces tenuipes mycelia was 4.12g/100g.
