摘要
目的:研究白芷提取液65℃和70℃加热过程中欧前胡素的浓度变化,为浓缩温度的设定提供依据。方法:采用高效液相色谱法,测定欧前胡素在65℃、70℃不同加热时间的浓度变化。结果:在65℃和70℃水浴恒温条件下,0～8 h欧前胡素浓度保持不变。结论:在65℃、70℃欧前胡素受热8 h浓度稳定。
Objective：To investigate the thermal stability of imperatorin in the extractive liquid of Angelicae Dahuricae Radix during heating process and provide basis for concentration temperature.Methods：The extractive liquid of Angelicae Dahuricae Radix was concentrated for 8 hours at 65 ℃ and 70 ℃ respectively.The content of imperatorin was quantified by HPLC at same time interval（1 h）.Results：The content of imperatorin had barely decreased under both conditions.Conclusion：The result indicated that imperatorin in Angelicae Dahuricae Radix remains stable in the process of concentration at 65 ℃ and 70 ℃ within 8 hours.
