分析兰坪虫草及其兰坪被毛孢的多种活性成分。分别用紫外分光光度法和HPLC法测定并分析了兰坪虫草、兰坪被毛孢和冬虫夏草中14种活性成分的含量,及来自4个样地的兰坪虫草和兰坪被毛孢的7种主要活性成分的含量。在14种成分中,兰坪虫草仅有3种成分与冬虫夏草具有显著差异,但其腺苷和2’-脱氧腺苷较低,可能对其药用价值有一定影响;兰坪被毛孢与冬虫夏草有6种成分具有显著差异,但其腺苷含量比兰坪虫草有显著提高,其多糖含量显著高于兰坪虫草和冬虫夏草,具有一定的开发利用优势。兰坪虫草的7种主要活性成分的含量在样地间差异较小,而兰坪被毛孢差异较大。兰坪被毛孢、兰坪虫草都与冬虫夏草的多种活性成分含量有较高的相似性,兰坪被毛孢有一定开发优势,但需在不同样地间开展优良菌株的筛选。
Analysis of a variety of active ingredients of Cordyceps sp. The content of 14 kinds of active ingredients in Cordyceps mongolica, Lantian spur and Cordyceps sinensis were determined and analyzed by UV spectrophotometry and HPLC respectively. The main active ingredient content. Among the 14 components, only three components of Cordyceps mongolicus had significant differences with Cordyceps sinensis, but its low adenosine and 2’-deoxyadenosine may have some influence on its medicinal value; Cordyceps sinensis has six components of significant differences, but its adenosine content than the Lanping Cordyceps significantly increased its polysaccharide content was significantly higher than the Lanping Cordyceps and Cordyceps sinensis, has some advantages of development and utilization. The contents of seven main active components of Cordyceps mongolicus in Lanping were less than those in Lanping. There was a high similarity among many active ingredients of C. punctatus and L. lappa in Lanping and Cordyceps sinensis in Lanping. However, there was some advantage in exploitation of C. sphaerocephala in Lanping, but good strains should be screened in different plots.
