Method for detecting contents of multiple components in liquorice heart-fire purging decoction

The invention relates to a method for detecting the content of multiple components in liquorice heart-fire purging decoction. The method comprises the following steps: preparing a test solution, preparing a reference solution, and performing ultra-high performance liquid chromatography detection; wherein the preparation of the test solution comprises the following steps: taking an extracting solution of the liquorice heart-fire purging decoction, centrifuging, taking a supernatant after centrifuging, volatilizing a solvent, adding a 50% methanol solution, dissolving, fixing the volume, and filtering by using a microfiltration membrane to obtain the test solution. According to the method for detecting the content of multiple components of the licorice heart-fire purging decoction, the separation degree of eight effective components is high, baseline separation can be achieved between every two adjacent components, the method is high in accuracy, good in linearity, good in precision and intermediate precision a
