The effect of cordycepin-enriched Cordyceps militaris JLM 0636 ($CM{\alpha}$) and Cordyceps militaris (CM) on fibrinolytic activity was investigated. The bioactive compounds and nutritional materials such as polyphenolic compounds, flavonoids, glutathione, minerals, and fatty acids were also measured. Concentrations of polyphenol compounds, flavonoids, and glutathione were higher in $CM{\alpha}$ than that in CM. The major minerals of both materials were K, Ca, Mg, and Na. The major fatty acids of both materials were linolenic acid, linoleic acid, oleic acid, and palmitic acid. Fibrinolytic activity was higher in $CM{\alpha}$ than that in CM. These results may provide the basic data to understand the fibrinolytic activity and bioactive compounds of $CM{\alpha}$.

The comparative effects of fibrinolytic, antioxidative activity and electrophoretical protein patterns with Cordyceps militaris powder (CM) and cordycepin-enriched Cordyceps militaris JLM0636 powder (CCM) and fermented cordycepin-enriched Cordyceps militaris JLM0636 powder by several microscopic organisms were investigated. In addition, nutritional materials such as mineral, protein, and fatty acids were also measured. The protein concentration was higher in CCM than that in CM. The protein concentration in fermented CCM was the highest in CCM treated by Aspergillus kawachii among the various samples. When total protein patterns of CM, CCM, and both fermented CCMs were analyzed by native- and SDS-PAGE, there were slightly varietal differences in electrophoretical protein patterns. Major minerals were K, Ca, Mg, and Zn. Major fatty acids were palmitic acid, stearic acid, oleic acid, linoleic acid, and linolenic acid. Fibrinolytic activity was the highest in the fermented CCM by Bs treatment among the various samples. The ${\alpha},{\alpha}^{\prime}$-diphenyl-${\beta}$-picrylhydrazyl (DPPH) radical scavenging activity was slightly stronger in the CCM treated with Aspergillus kawachii among the various samples; however, these samples all exhibited relatively low levels of activity compared with the butylated hydroxytoluene (BHT). These results may provide the basic data necessary to understand the biological activities and chemical characteristics of Cordyceps militaris JLM0636 powder fermented by several microscopic organisms to develop functional foods.

The antioxidative activity and bioactivity of water, ethanol, and methanol extracts from Paecilomyces japonica (PJ), Cordyceps militaris (CM), and cordycepin-enriched C. militaris JLM0636 ($CM{\alpha}$) were tested in in vitro experimental models. The PJ water extract showed the highest extraction yield (42.53%). The highest content of phenolic compounds and flavonoids were found in the water extract of PJ, 2.72% and 1.73%, respectively. The major minerals were K, Mg, and Ca. The water extracts of PJ also showed the highest DPPH free radical scavenging activity and reducing power. Linoleic acid peroxidation and antioxidative activities were strong in $CM{\alpha}$. The methanol extracts of PJ showed the highest inhibition activity against tyrosinase. Fibriolytic activity was higher in $CM{\alpha}$ than in CM. These results may provide basic data to understand the biological activities of bioactive materials derived from $CM{\alpha}$ for the development of functional foods, cosmetics, and antithrombotics.

The concentration of cordycepin produced by crossbred Cordyceps militaris JLM 0636 (CM${\alpha}$) was 7.42 mg/g dry weight, which was 7-fold higher than that of C. militaris (CM). However, cordycepin was not detected in Paecilomyces japonica (PJ). The improvement effects of CM${\alpha}$, CM and PJ on orotic acid (OA)-induced fatty liver in male Sprague-Dawley rats was investigated. Rats were randomly divided into five groups (n=6) based on five dietary categories: normal (N), OA control (C), OA plus 3% (w/w) PJ (PJ), OA plus 3% CM (CM), and OA plus 3% CM${\alpha}$ (CM${\alpha}$). OA treatment induced the retardation of body weight gain and enlargement of the liver. The concentration of hepatic triglyceride was markedly increased by OA-feeding, whereas this rise was significantly reduced by simultaneous feeding of OA, PJ, CM, and CM${\alpha}$, and this phenomenon was more pronounced by cordycepin-enriched CM${\alpha}$. The contents of total lipid, triglyceride, and free fatty acid in the serum were significantly or slightly lower in the OA control group than those of the N group, but there were no significant differences among the OA treatment groups. The hepatocytes in the OA-induced fatty liver contained numerous large lipid droplets, but PJ, CM, and CM${\alpha}$ feeding prevented the OA-induced lipid droplet accumulation in the hepatocytes. This effect was more pronounced in cordycepin-enriched CM${\alpha}$ than in PJ or CM in OA treatment rats. Accordingly, cordycepin-enriched CM${\alpha}$ could be an ideal candidate material as a dietary supplement in healthy functional foods to improve the effects of fatty liver.
