| Abstract: | A study was conducted to extract cordycepin from Cordyceps militaris(L). Link. Effects of solvents(water,methanol and ethanol),the ratio of solid to liquid,temperature and extraction time on extraction rate of cordycepin were analysed. The optimal experimental conditions were obtained as extraction temperature 70 degrees C,the ratio of solid to liquid 1:20,extraction time 15 min,microwave power 400 W. Moreover,the content of cordycepin was determined by HPLC. |
