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.
目的
研究不同温度下补骨脂中补骨脂素和异补骨脂素的总含量变化，并通过初匀速稳定性试验预测其有效期，为评价其质量提供依据。
方法
用初速度V代替反应速率常数K。根据Arrhenius规则，获得室温下的储存期。
结果
确定补骨脂的稳定期为0.53年。
结论
高温不利于补骨脂的稳定性，需存放在阴暗凉爽处。
