This review discusses the possible use of cultivated C. militaris as an effective substitute for native O. sinensis in the face of ever-increasing prices of O. sinensis because of its short supply. On the one hand, cultivated C. militaris contains higher levels of cordycepin when compared with that of wild-type O. sinensis and cultivation of C. militaris has been shown to be capable of reducing the risk of heavy metal contamination. On the other hand, there is a paucity of robust in vivo studies and randomized controlled tests comparing the pharmacology and use of C. militaris and O. sinensis. For extraction of cordycepin as western-style tablets, the use of cultivated C. militaris rather than O. sinensis represents the most appropriate future approach. For many other purposes, comparative pharmacology and clinical trials are in urgent needs.展开更多

Based on the finding that there is a high concentration of cordycepin in both natural and cultured Cordyceps kyushuensis, the in vitro antitumor activity of cordycepin and the water extracts of Cordyceps kyushuensis has been investigated.

We previously reported that the growth of B16-BL6 mouse melanoma (B16-BL6) cells and mouse Lewis lung carcinoma (LLC) cells was inhibited by cordycepin (3’-deoxyadenosine), an ingredient of Cordyceps sinensis, and its effect was antagonized by MRS1191, a selective adenosine A3 receptor (A3-R) antagonist although adenosine (up to 100 μM) had no effect on the growth of B16-BL6 and LLC cells. In this study, we investigated whether water extracts of Cordyceps sinensis (WECS) inhibit the growth of B16-BL6 cells, LLC cells, HT1080 human fibrosarcoma (HT1080) cells and CW-2 human colon carcinoma (CW-2) cells via their A3-R. As a result, the growth of all cell lines were potently inhibited by WECS (10 μg/mL) and the inhibitory effect of WECS was significantly antagonized by MRS1191 (1 μM). Furthermore, WECS included 2.34% w/w cordycepin and 0.12% w/w adenosine as components according to the HPLC- ECD system. In conclusion, WECS inhibited the proliferation of four cancer cell lines by stimulation of A3-R and the main component in WECS with anticancer action might be cordycepin instead of adenosine.展开更多

It refers to nutrient and vitamin absorption, food digestion and various infectious diseases. The Paecilomyces hepiali and Cordyceps militaris are highly enriched with cordycepin and ergosterol which are considered as anti bacterial substances. Present study finds out comparative effect of hot water extract of particular fungal material on growth of six species of gastrointestinal bacteria that belong to both aerobic and anaerobic and, consist with harmful and commensal categories. The appropriate concentration level of hot water extract of both strains was identified. The individual specific bacterial growing media were prepared and calculated;amounts of bacteria cultures were inoculated by using micro pipettes. The optical density and number of bacterial colonies were measured after 24 hours. The pure mycelial extract of P. hepiali with 2 × 10-3 g/ml of concentration has significant effect on depleting the growth of E. coli, E. faecalis, S. aureus, L. gasseri and B. ovatus bacteria. B. longum has no significant effect by particular extract. Same type of extract of C. militaris has significantly reduced the growth of every bacteria used in this study. Hot water extract of C. militaris cultivated on soy bean has significant growth retardation toward E. coli, E. faecalis, S. aureus and L. gasseri. It has stimulated the growth of B. ovatus and B. longum which are considered as beneficial bacteria for human gut. This study shows that extracts of both mycelia include antimicrobial substances like cordycepin and ergosterol which can be used as food supplements to enhance human gut health.展开更多
