摘　　要：以施加不同浓度亚硒酸钠的培养基来栽培出的蛹虫草子实体为对象,研究了硒对蛹虫草中主要营养成分蛋白质、氨基酸及其主要活性成分虫草酸、虫草多糖、腺苷含量的影响,并进一步探究硒对蛹虫草蛋白分布的影响。结果表明,硒可以提高蛹虫草子实体中蛋白质、虫草酸、虫草多糖和氨基酸的含量,硒对蛹虫草中腺苷的含量无影响。硒并不改变蛹虫草蛋白质的分布,硒在蛋白质中是以取代硫的形式而存在的。The effect of selenium on the nutritional components of Cordyceps militaris（CM） such as proteins, amino acids and on the active components such as Cordycepic acid, Polysaccharide, and adenosine was studied using CM which was obtained by cultibating CM in the substrate added different content of Na2SeO3 as tested samples. The results showed that the contents of proteins, Cordycepie acid, Polysaccharide and amino acids of CM can be Advanced by selenium. Selenium has not effect on adenosine of. CM, Moreover, selenium hardly changed the distribution of proteins in CM , Sulphur was replaced by Selenium in protein of CM.
