SINOPSIS

Forty isolates of Ophiocordyceps sinensis collected from Himalayan alpine meadows of Uttarakhand, India, and cultivated on Jhangora (Echinochloa crusgalli) grains were screened to identify the isolate(s) of high cordycepin content. The cultured mycelia were extracted with 50% methanol-chloroform and analyzed by HPTLC using chloroform:methanol (6:1 v/v) as mobile phase and densitometry scanning at 263 nm. Cordycepin varied from 0.002% to 0.029% was detected in twenty-one isolates. Compared to natural O. sinensis (0.004%, 0.006%), cordycepin was determined to be enhanced in twelve cultured samples.
