OBJECTIVE: To study the total content change of psoralea and isopsoralea in Psoralea corylifolia under different temperature, and predict its term of validity by initial average rate stability test in order to provide the basis for assessing its quality. METHOD: The reaction rate constant K was replaced by initial velocity V. According to Arrhenius rule, storage period was obtained at room temperature. RESULT: The stable life of P. corylifolia has been determined as 0.53 years. CONCLUSION: The high temperature is not conducive to the stability of the P. corylifolia, which need to store in a dark and cool place.
