摘　　要：通过国标方法测定青海省玉树2个主产地冬虫夏草原草的水分、灰分、蛋白质、氨基酸、无机元素、粗多糖、腺苷、虫草酸、和虫草素等成分的含量。结果显示:2个样品间各成分含量基本一致,其中灰分含量为4.6%~4.7%、粗蛋白含量为31.57~33.75%、总氨基酸为23.12%~23.73%,粗多糖含量为10.53%~11.19%,腺苷含量为0.18~0.33 mg/g,虫草酸含量为105.34~131.75 mg/g,虫草素未检测到。This study examined two samples of Ophiocordyceps sinensis from two main producing regions in Yushu stat and Qinghai Province( Haxiu and Guoqin). The content of moisture,ash,protein,aminoacids,inorganic elements,polysaccharide,adenosine,D-mannitol and cordycepin were analysed by the national standard method. Results showed that the amunt of each component was about the same in two samples: ash 4. 6% ~ 4. 7%,crude protein31. 57% ~ 33. 75%,total amino acid 23. 12% ~ 23. 73%,crude polysaccharide 10. 53% ~ 11. 19%,adenosine content 0. 18 ~ 0. 33 mg / g,D-mannitol 105. 34 ~ 131. 75 mg / g and no cordycepin was detected. The detection results will provide a good data foundation for Yushu Ophiocordyceps sinensis characteristic identification.
