摘要
为了探讨不同提取方法对黄芩苷含量的影响,以黄芩苷含量为观察指标,用高效液相色谱法测定其含量,通过75%乙醇、水、碱水(pH=9)和碱水(pH=11)进行热回流提取、超声提取平行对比实验。结果表明,热回流提取法对黄芩苷提取率优于超声提取法,并且优选出的热回流提取法工艺简单、操作方便、环保,提取效果好,可为黄芩资源的合理开发利用提供一定的理论依据。
In order to discuss the effect of different extraction methods on content of baicalin, with observation of baicalin content as indicators, using high-performance liquid chro the determination of the content, with 75% alcohol, water, alkaline（pH=9） and alkaline （pH=1 1） heat reflux extraction, ultrasonic extraction parallel contrast experiment is done, effects of different extraction methods on baicalin extraction rate influence is studied. Results showed that the optimized heat reflux extraction has the advantages of simple process, convenient operation, environmental protection, good extracting effect. It provides certain theory for rational development and extraction resources.
