    Abstract:
    To establish a new quantitative method for simultaneous determination of multi-components in Scrophularia root by using high performance liquid chromatography (HPLC) and validate its feasibilities．Meanwhile,using catalpol as one chemical reference substance to establish the relative correct factors and relative retention values of aucubin,harpagide,acteoside,angoroside C,harpagoside and cinnamic acid．Then using the quantitative analysis of multi-components by single-marker (QAMS)model,the six analytes can be quantitatively determined in Scrophularia root．The method was evaluated by comparison of the quantitative results to external standard method．No significant differences were observed between the quantitative results of the two methods．The obtained RCFs were credible．It is feasible and suitable to evaluate the quality of Scrophularia root.
