Article Abstract

Objective: To study the antimutagenicity of Cordyceps taii polysaccharide (CDPl).

Methods: Ames test and micronucleus form assay of polychromatic erythrocytes in mice bone marrow were used to evaluate the antimutagenic effect of CDPI with different concentrations.

Results: CDP1 could inhibit the reverse mutation on Salmonella typhimuriun strains TA97, TA98, TA100 and TA102 without S9 in different degree, especially remarkable in the strains T97 ,T98 and T102. The maxium inhibition rates of strains TA97, TA98, TA100 and T102 were 68.5%, 79.5%,19. 8% and 81.3%, respectively. In addition, CDPI could significantly reduce micronucleus frequencies induced by cyclophosphamide, and the rate of maxium inhibition was 70.3%.

Conclusion: Cordyceps taii polysaccharide possesses significantly antimutagenic properties.

The antibacterial agent helvolic acid, which was isolated from the active antitumor fraction of Cordyceps taii, showed potent cytotoxicity against different human cancer cells. In the present study, the in vivo antitumor effect of helvolic acid was investigated in murine sarcoma S180 tumor-bearing mice. Doses of 10 and 20 mg/kg/day helvolic acid did not exert significant antitumor activity.

Objective: To seperate and identify the chemicals from the antitumor fraction of Cordyceps taii mycelia powder.

Methods: The mycelia of Cordyceps taii were prepared by the submerged fermentation technique. Chemical entities in the antitumor fraction of Cordyceps taii were isolated and purified by using different column chromatographies (silica gel, Sephadex LH-20 and MCI), and semi-preparative HPLC method.
