- Abstract: This study is to establish the HPLC specific chromatogram and determine four main effective components of Lamiophlomis Herba and its counterfeit.Chlorogenic acid, forsythoside B, acteoside and luteoloside were reference substance.HPLC analysis was performed on a Waters XSelect C₁₈ column (4.6 mm×250 mm,5 μm).The mobile phase was acetonitrile-0.5% phosphoric acid solution (18∶82) with isocratic elution.The flow rate was 1.0 mL•min⁻¹, the detection wavelength was 332 nm and the column temperature was 30 ℃.Chemometrics software Chempattern was employed to analyze the research data.HPLC specific chromatogram of Lamiophlomis Herba from different samples were of high similarity, but the similarity of the HPLC specific chromatogram of its counterfeit were less than 0.65.Both of cluster and principal component analysis can distinguish certified products and adulterants.The HPLC specific chromatogram and contents of four effective components can be used for the quality control of Lamiophlomis Herba and its preparations.It provided scientific basis to standardize the use of the crude drug.
