The invention relates to a detection method for Naoxinqing capsules, belongs to the technical field of traditional Chinese medicines and provides the detection method for the Naoxinqing capsules. Through the method, the quality of the Naoxinqing capsules can be better controlled. The method comprises the following step of carrying out scopoletin detection: using octadecylsilane chemically bonded silica as a filler, using methanol and 0.1 percent formic acid as flowing phases, adopting the detection wavelength of 345nm, taking a right amount of scopoletin reference sample, adding methanol to prepare into a reference solution, taking materials in the Naoxinqing capsules under the content uniformity item, precisely adding a methanol solution, carrying out ultrasonic processing, filtering, taking subsequent filtrate so as to obtain a test solution, respectively and precisely sucking the reference solution and the test solution, injecting the reference solution and the test solution into a liquid chromatograph, carrying out measurement, calculating by a peak area according to an external standard method so as to obtain the content of the scopoletin. The Naoxinqing capsules are detected according to the method, if the content of the scopoletin in each capsule is less than 5[mu]g, the drug is unqualified.
