RESUMO
Objective To establish a methodological study pattern of quantitative analysis of multi-components by single marker ( QAMS) , and examine its feasibility and technical applicability in the quality control of compound preparation of traditional Chinese medicine-Jinhoujian spray. Methods Gas chromatographic method ( GC) was used and naphthalene served as the internal standard. Menthol was used as the reference substance. The relative correlation factors ( RCF) of 1,8-Cineole, camphor and borneol to menthol were calculated and established to carry out QAMS.The accuracy of this method was confirmed by comparison of internal standard method. Results The reproducibility of relative correction factor was perfect. The two methods did not show significant difference in 10 bathes of samples. Conclusion The QAMS method is feasible, credible, and can be used to determine active ingredients in Jinhoujian spray.
