Method for simultaneously detecting contents of four effective ingredients in antitussive tablet

The invention provides a method for simultaneously detecting contents of four effective ingredients (including schisandrin, praeruptorin A, praeruptorin and shionone) in an officinal antitussive tablet. The method comprises the steps of applying a modern high performance liquid chromatography technology, and taking octodecyl silane bonded silica gel as a filling agent; taking acetonitrile as a mobile phase A, and water as a mobile phase B; and calculating the number of theoretical plates to be not less than 5000 according to a schisandrin peak. In an elution process, gradient elution that allows a concentration proportion of the mobile phase A to the mobile phase B to change gradually is combined with isocratic elution that allows a proportion of the mobile phase A to the mobile phase B to be constant, so that a specific gradient elution procedure is formed; two or three gradient elutions are conducted; and the change detection is conducted on wavelength in a gradient elution process. The method can simultaneously detect the contents of schisandrin, praeruptorin A, praeruptorin and shionone in the antitussive tablet qualitatively and quantitatively, is simple, convenient, quick and high in specificity, and can raise the quality control level of the antitussive tablet effectively.
