摘要/Abstract

摘要：

冬虫夏草作为青藏高原特有的生物资源，对生长环境有着极其特殊的要求。通过调查青海省冬虫夏草资源分布状况，选取玉树、果洛、黄南、海南等地区的冬虫夏草进行氨基酸、微量元素含量检测，以反映冬虫夏草资源特征。研究结果表明，青海省冬虫夏草含有丰富的氨基酸和微量元素，且冬虫夏草不同部位的氨基酸、微量元素含量有明显差别。将青海省冬虫夏草与其他产区的冬虫夏草氨基酸含量进行对比分析，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，和西藏产区的冬虫夏草氨基酸含量基本一致。

Abstract:

Ophiocordyceps sinensis is an entomophagous fungus endemic to alpine regions of the Tibetan Plateau. It has been long known by its synonym Cordyceps sinensis both in scientific and nonscientific communities. O.sinensis, a unique entomophagous fungus parasitizing the larvae of the genus Thitarodes, mainly distributed in the alpine meadows of the QinghaiTibet Plateau, is known as a valuable invigorant of traditional Chinese medicine for centuries in China. In order to research characteristics of O.sinensis, taking sample from Dalag County to laboratory for measuring content of amino acids and elements, and comparing the results with other examples selected from Sichuan, Yunnan and Tibet. The results show that content of amino acids is ample in O.sinensis, and the level of contents is clearly visible from basal caterpillar to stroma. Comparison with examples of Yunnan, Sichuan and Tibet, the amino acids is in average level. In addition, there were abundant mineral elements in O.sinensis.

Key words: Ophiocordyceps sinensis, Tibetan Plateau, Ecological environment
