<p><b>OBJECTIVE</b>To discriminate Descurainiae Semen and Pantagirus Semen.</p><p><b>METHOD</b>A high-performance liquid chromatographic method was developed to establish the fingerprint of Descurainiae Semen, and hierarchical cluster analysis (HCA) and partial least squares discriminant analysis (PLS-DA) were applied to study HPLC fingerprinting and chemical recognition.</p><p><b>RESULT</b>There exists large difference of chromatographic peaks and its relative peak area of HPLC fingerprints between Descurainiae Semen and Pantagirus Semen, and after conducting statistical analysis, the result demonstrated that all samples were classified into three categories: Descurainiae Semen, Pantagirus Semen and their mixtures.</p><p><b>CONCLUSION</b>The developed HPLC fingerprint combined with chemometrics can be utilized to discriminate between Descurainiae Semen and Pantagirus Semen, which was quick, simple, accurate and reliable an can provide the basis for the characterization and quality assess of Descurainiae Semen and Pantagirus Semen.</p>

"Tinglizi", the ripe seed of Descurainia sophia and Lepidium apetalum, is a member of Brassicaceae (Cruciferae). Traditionally, the former is called "Nantinglizi" (Descurainiae Semen) while the latter is called "Beitinglizi" (Lepidii Semen). In the theory of traditional Chinese medicine, it has the power to purge lung-fire, relieve dyspnea, promote diuresis and reduce edema, and it is mainly indicated in a case with phlegm-fluid accumulation, cough with excessive sputum, dyspnea with being unable to lie, and general swelling. In view of its wide-spread application in clinic, a comprehensive review of Lepidii Semen and Descurainiae Semen was conducted from the following aspects: herbalogical study, variety identification, historical evolution of processing, chemical constituents, pharmacological effects, quantitative determination and toxicity which could provide reference for further research and development of "Tinglizi".
