A method for measuring contents of 14 chemical components in a traditional Chinese medicine composition is disclosed. HPLC-MS/MS is adopted to simultaneously measure the contents of the 14 chemical components in the composition. The composition is a pulse-invigorating heart-tonifying pill. The 14 chemical components include emodin, lobetyolin, 2,3,5,4'-tetrahydroxy stilbene-2-O-beta-D-glucoside, glycyrrhizic acid, liquiritin, liquiritigenin, polydatin, rutoside, isoliquiritigenin, ononin, verbascoside, gallic acid, schizandrin, and rhein. The method includes building standard curves of the 14chemical components; acquiring multi-reaction ion chromatograms of the 14 chemical components in the pill; and determining the contents of the 14 chemical components in the pill. The method has characteristics of high sensitivity, high reliability, a high efficiency and capability of being rapid. Through measuring the contents of the 14 chemical components in the pill, quality control on the pillcan be more effectively performed, thus ensuring clinical treatment effects of the pill.
