Abstract：
 The invention relates to a identification method for drugs with characteristic graphoes. The method acquire the characteristic graphoes with liquid phase chromaspectrum-mass spectrum combining technology and identify medicine with the characteristic graphoes. The identification method provided by the invention is based on the characteristic graphoes,the steps includes data acquirement, chromatography matching, the data normalization processing,the characteristic selection and the characteristic graphoes establishment. The invention has the following advantages and remarkable effect compared to the current method of adopting the original fingerprint map to identify drugs: 1)the specification of the data acquisition system is low,the characteristic graphoes has good stability, specificity and objectivity; 2)the characteristic graphoes causes the increas of the difference of the sample in the same category and between the different categories, getting better category charateristics, its identifying ability is better than the original fingerprint graphoes; 3)the identification result of the drugs is accurate, available and reliable.
