【中文摘要】 對人工馴化的廣東蟲草(Cordyceps guangdongensis)子實體進行成分分析,并與冬蟲夏草和蛹蟲草進行比較。結(jié)果表明,廣東蟲草的蟲草酸含量較高,達151.00 mg/g,高于冬蟲夏草(127.80 mg/g)和蛹蟲草(39.00 mg/g);腺苷為0.81 mg/g,是冬蟲夏草的3倍;蟲草素為0.02 mg/g,粗蛋白為27.5%;水解氨基酸總量為15%。

【英文摘要】 Levels of selected chemical components in fruit bodies of a newly described species of Cordyceps,Cordyceps guangdongensis,were determined and compared with those present in Cordyceps sinensis and Cordyceps militaris.C.guangdongensis fruit bodies contained the highest concentrations of cordycepic acid(151.00 mg/g compared to 127.80 mg/g and 39.00 mg/g for C.sinensis and C.militaris,respectively),although cordycepin levels(0.02 mg/g) were much lower compared to C.militaris(1.70 mg/g).Adenosine levels(0.81 mg/g) were 3-fold higher compared to C.sinensis(0.27 mg/g) but less than half the adenosine content of C.militaris(1.76 mg/g).C.guangdongensis fruit bodies contained 27.5% crude protein and had a total amino acid content of 15%.
