ABSTRACT

Cordyceps militaris are widely cultivated in China for an important raw material for health foods. CM-H0810 is a C. militaris strain used in the production of C. militaris in Shanghai, the surrounding areas of Shanghai, and Guangdong province in China. We evaluated the effect of culture time on the bioactive components in the fruit bodies of C. militaris CM-H0810 to provide scientific references for production of C. militaris fruit bodies with good quality. The results showed that the polysaccharide contents increased gradually during 35-45 d, but it declined with the prolongation of culture time. The highest polysaccharide content was 3.46% at 45 d. With the prolongation of culture time the cordycepin content gradually increased; the highest cordycepin content was 3.57 μg/mg at 60 d, which increased 321% compared to that at 35 d. Contrary to cordycepin, the adenosine content declined gradually, with the highest content of 1.86 μg/mg at 35 d and the lowest content of 1.48 μg/mg at 60 d. Our study indicates that it is necessary to select suitable harvest times in view of different compounds that are desirable to obtain in high quantities.
