摘　　要：为研究富硒金针菇对人体健康的影响,采用富硒栽培、全自动氨基酸分析仪、苯酚-硫酸法对金针菇子实体总糖、氨基酸的种类和含量进行测定研究。结果表明:金针菇子实体均含有总糖、总氨基酸和游离氨基酸17种,其中人体必需氨基酸7种。确定硒糖的最佳浸提温度80℃、浸提时间3 h、提取3次合并滤液;总糖菌盖、菌柄含量分别为40.31%、48.99%,硒含量为34.2355μg/g。In order to study Se Flammulina velutipes on human health issues. Using selenium-rich cultivation, automatic amino acid analyzer, phenol-sulfuric acid method Flammulina velutipes total sugar, amino acids the type were content measured study. The results showed that： Flammulina velutipes fruiting bodies contained total sugar, 17 kinds of amino acids and free amino acids, including 7 kinds of essential amino acids. Determining the optimum leaching selenium sugar temperature 80℃, extraction time 3 h, extracted 3 times the combined filtrate;total sugar pileus, stipe contents were 40.31%, 48.99%, selenium content of 34.2355μg/g.
