Abstract: |
A method was established for the high-throughput and rapid analysis of characteristics chemical components in Brucea javanica oil and its oral drugs by direct injection electrospray ionization ultra high resolution mass spectrometry(DI-ESI-UHRMS) combined with statistical data analysis strategy.Based on the characteristics of DI-ESI-UHRMS with high resolution,high-throughput and non-targeted,69 accurate molecular formulas were resolved(the error with theoretical value is less than 1 ppm) in positive ion mode by analysis of the accurate mass number and fine isotope peak information for Brucea javanica oil and soybean lecithin soft capsule.Combining data from secondary mass spectrometry,literature,and Lipid Maps website,semi-identification of 69 accurate molecular formulas was performed,which were carbohydrates,phospholipids,oleic acids and oils composition.The results of component analysis(PCA),orthogonal partial-least squares discriminant analysis(OPLS-DA) and hierarchical cluster analysis(HCA) showed that Brucea javanica oil,olive oil and canola oil did not contain phospholipids,and the mother peak(m/z) corresponding to 69 semi-identified molecular formulas could be used as the index component for the identification of false adulteration of Brucea javanica oil and the difference analysis of oral preparations.This study provides a theoretical support for further improving the quality standards of Brucea javanica and its preparations. |
