OBJECTIVE
To study the content change of chlorogenic acid in honeysuckle under different temperature, and predict its term of validity at room temperature.
METHOD
The content of chlorogenic acid was assayed by HPLC. The activation energy E(a) and the decomposition rate constant K were calculated by initial average rate stability tests and the prediction was carried out.
RESULT
The stable life of honeysuckle has been determined as 1.29 years.
CONCLUSION
The initial average rate stability test was used to predict stable life of honeysuckle, and the results are credible. Higher temperature should be avoided for honeysuckle store, and room temperature should guarantee its quality during storage.
目的
研究不同温度下金银花中绿原酸含量的变化，并预测其室温下的有效期。
方法
采用高效液相色谱法测定绿原酸含量。通过初均速稳定性试验计算活化能E(a)和分解速率常数K，并进行预测。
结果
确定金银花的稳定期为1.29年。
结论
采用初均速稳定性试验预测金银花的稳定期，结果可靠。金银花储存应避免高温，室温下储存应保证其质量。
