description The invention discloses a method for identifying radix ophiopogonis, fructus forsythiae and baicalin in granules for clearing throat and throat, and relates to the technical field of quality control of traditional Chinese medicines. The preparation method mainly improves a preparation method of a test solution, and specifically comprises the following steps: boiling the radix ophiopogonis test solution with methanol and sodium hydroxide, and extracting with trichloromethane and n-butyl alcohol to prepare the radix ophiopogonis test solution; the fructus forsythiae test solution is prepared by boiling calcium carbonate and water, adding magnesium oxide, evaporating to dryness, and performing ethanol reflux extraction; the baicalin test solution is prepared by adding alkaline 50% ethanol into the baicalin test solution for ultrasonic treatment, and then adding 50% ethanol to complement the reduced weight. By improving the preparation method of the test solution, the purity and the concentration of the sample to
