Selenium-enriched Cordyceps militaris fruit bodies are industrially cultivated as functional food or medicinal food in China and southeast Asia. However, composition of selenium compounds and distribution of the main bioactive components are still unknown. In the selenium-enriched fruit bodies, the main soluble selenium compounds of low molecular weight were identified as SeMet (selenomethionine), and the main selenium compounds bound in proteins were identified as SeMet and SeCys (methylselenocysteine). Trace minerals as Se (selenium), Zn (zinc), Fe (iron) and the main active components as adenosine, cordycepin and carotenoids were mostly distributed in the terminal of fruit bodies, while P (phosphorus) and K (potassium) were evenly distributed in the fruit bodies. The results indicated that terminal of the fruit bodies should be the better materials for production of advanced functional food. So cultivation of relatively short and thick fruit bodies with bigger terminals deserves further research.
富硒蛹虫草子实体在中国和东南亚被作为功能性食品或药用食品进行工业化栽培。然而，硒化合物的组成和主要生物活性成分的分布仍不清楚。在富硒子实体中，低分子量的主要可溶性硒化合物被鉴定为 SeMet（硒代蛋氨酸），而结合在蛋白质中的主要硒化合物被鉴定为 SeMet 和 SeCys（甲基硒代半胱氨酸）。痕量矿物质如 Se（硒）、Zn（锌）、Fe（铁）和主要活性成分如腺苷、蛹虫草素和类胡萝卜素主要分布在子实体的末端，而 P（磷）和 K（钾）则均匀分布在子实体中。结果表明，子实体的末端应该是生产高级功能性食品的更好材料。因此，进一步研究具有较大末端的相对较短而粗壮的子实体的栽培是值得的。
