Methods: In this study, a simple and efficient high-performance liquidchromatography (HPLC) method integrating with chemometric analysis and spectrum-antitumor effect relationship wasdeveloped for discrimination between two species of Mylabris: Mylabris phalerata Pallas (MP) and Mylabris cichoriiLinnaeus (MC). Results: In the fingerprint analysis, 14 characteristic peaks were selected to assess the differencesbetween MP and MC using the similarity and pattern recognition analysis using PCA and OPLS-DA. The HPLCchromatograms of samples from 10 regions of China showed differences between MP and MC, and 7 characteristicchemical markers were found. In the spectrum-antitumor effect relationship analysis, 4 activity markers played a vitalrole in decreasing the IC50 and might be the antitumor components of Mylabris by grey relational analysis andmultivariate linear regression analysis. The chemometric analysis in combination with spectrum-effect relationshipresults indicated that peaks 2 (cytosine), 4 (unknown) and 14 (unknown) were important differential markers fordistinguishing the two species of Mylabris. Conclusion: The method is applicable, credible and more efficient todiscriminate MP and MC, and will offer a new way for facilitating quality control of insect medicines.展开更多
