ABSTRACT
A method of ultra-fast liquid chromatography in series with tandem mass spectrometry for the rapid and sensitive detection of 57 compounds in Spatholobi Caulis (the vine stem of Spatholobus suberectus Dunn) within 35 min was established. This assay can simultaneously determine a variety of compounds without matrix interference in multiple reaction monitoring mode including evaluating the quality of different batches of Spatholobi Caulis from several areas and further identifying the characteristic compounds efficiently. After comprehensive validation, this method can be used to determinate samples rapidly, precisely, accurately, repeatably, and sensitivity. There were significant content differences in 12 batches of Spatholobi Caulis, which were further classified and systematically differentiated applying multivariate statistical analysis. Furthermore, orthogonal partial least squares discrimination analysis results indicated that (-)-gallocatechin (10), (-)-epiafzelechin (20), 4,7,2'-trihydroxy-4'-methoxyisoflavanol (51), and biochanin A (53) characterize compounds to discernment internal quality of Spatholobi Caulis, and recommended as quality control indicators. Hence, presented work provides a method for further study on pharmaceutic preparation, metabolism, as well as for the design, production optimization process, and clinical application.
