A method for identifying and isolating the active fractions in fungus Cordyceps sinensis. It covers a findings of the structure of an active compound that is present in the active fractions, an isolation method that can be used to extract the active fractions and a specific active compound, and the use of F8, one specific active compound, that is present in the active fractions thus isolated, to improve the clinical symptoms of bronchial hyperresponsiveness and pulmonary injury in OA induced BNR model with enhancing Th1 cytokines suppressing Th2 and iNOS cytokines mRNA expression. This work has important pharmacological implications for the prevention and treatment of bronchial asthma in humans.
