摘要： 通过分析青海省气温、光照、降水分布规律和冬虫夏草对气候生态因子的要求，玉树、果洛、黄南、海南等地区均有冬虫夏草分布。在此基础上，分别从4个地区选择冬虫夏草样品进行氨基酸含量检测，以反映青海省冬虫夏草资源特征。研究表明：青海省冬虫夏草含有丰富的氨基酸，且冬虫夏草不同部位的氨基酸含量差别显著。将青海省冬虫夏草与其他产区的冬虫夏草氨基酸含量对比分析表明，青海省冬虫夏草氨基酸含量低于四川、云南产区的冬虫夏草，与西藏产区的冬虫夏草氨基酸含量基本一致。

Abstract: Cordyceps sinensis is an endemic species of entomophagous fungus distributed in the alpine regions of the Qinghai-Tibet Plateau. It has been long known by its synonym C. sinensis both in scientific and non-scientific communities. C. sinensis, a unique entomophagous fungus parasitizing the larvae of the genus Thitarodes, is mainly distributed in the alpine meadows of the Qinghai-Tibet Plateau, and known as a valuable invigorant in traditional Chinese medicine for centuries in China. In order to research the properties of C. sinensis, some samples were collected from Qinghai Province, the contents of amino acids and elements were measured in laboratory, and the results were compared with those of other samples collected from Sichuan and Yunnan provinces and Tibet Autonomous Region. The conclusions show that the contents of amino acids are ample in C. sinensis, and the level of contents is clearly visible from basal caterpillar to stroma. Compared with the samples collected from Yunnan, Sichuan and Tibet, the contents of amino acids in C. sinensis samples collected from Qinghai Province were in average level. In addition, there were abundant mineral elements in C. sinensis.
