Chemical profiling and quantification of XueBiJing injection, a systematic quality control strategy using UHPLC-Q Exactive hybrid quadrupole-orbitrap high-resolution mass spectrometry.

ABSTRACT: To clarify and quantify the chemical profiling of XueBiJing injection (XBJ) rapidly, a feasible and accurate strategy was developed by applying ultra high performance liquid chromatography-Q Exactive hybrid quadrupole-orbitrap high resolution accurate mass spectrometry (UHPLC-Q-Orbitrap HRMS). A total of 162 components were characterized, including 19 phenanthrenequinones, 33 lactones, 28 flavonoids and 12 phenolic acids and 51 other compounds. Among them, 38 major compounds were unambiguously quantified by comparing with reference standards. Meanwhile, 38 representative compounds were simultaneously detected in XBJ samples by Q-Orbitrap HRMS. Satisfactory linearity and correlation coefficient were achieved with wide linear range. The precisions, repeatability, stability and recovery were meeting requirements. The validated method was successfully applied for simultaneous determination of 38 bioactive compounds in 10 batches XBJ samples. In addition, the similarity evaluation of fingerprintings was applied to assess the quality of XBJ. And the results were evaluated by multiple statistical strategies and five compounds might be the most important chemical markers for chemical quality control of XBJ. Finally, a rapid and simple UPLC-MS/MS method was developed for determination of five markers in XBJ sample. This research established a high sensitive and efficient strategy for integrating quality control, including identification and quantification of XBJ.

Project description:There is an immediate need for improved methods to systematically and precisely quantify large sets of peptides in complex biological samples. To date protein quantification in biological samples has been routinely performed on triple quadrupole instruments operated in selected reaction monitoring mode (SRM), and two major challenges remain. Firstly, the number of peptides to be included in one survey experiment needs to be increased to routinely reach several hundreds, and secondly, the degree of selectivity should be improved so as to reliably discriminate the targeted analytes from background interferences. High resolution and accurate mass (HR/AM) analysis on the recently developed Q-Exactive mass spectrometer can potentially address these issues. This instrument presents a unique configuration: it is constituted of an orbitrap mass analyzer equipped with a quadrupole mass filter as the front-end for precursor ion mass selection. This configuration enables new quantitative methods based on HR/AM measurements, including targeted analysis in MS mode (single ion monitoring) and in MS/MS mode (parallel reaction monitoring). The ability of the quadrupole to select a restricted m/z range allows one to overcome the dynamic range limitations associated with trapping devices, and the MS/MS mode provides an additional stage of selectivity. When applied to targeted protein quantification in urine samples and benchmarked with the reference SRM technique, the quadrupole-orbitrap instrument exhibits similar or better performance in terms of selectivity, dynamic range, and sensitivity. This high performance is further enhanced by leveraging the multiplexing capability of the instrument to design novel acquisition methods and apply them to large targeted proteomic studies for the first time, as demonstrated on 770 tryptic yeast peptides analyzed in one 60-min experiment. The increased quality of quadrupole-orbitrap data has the potential to improve existing protein quantification methods in complex samples and address the pressing demand of systems biology or biomarker evaluation studies.
