Mapping Royal Jelly's Bioactive Profile by Liquid Chromatography Coupled to Trapped Ion Mobility Spectrometry and High-Resolution Mass Spectrometry.

ABSTRACT: An innovative 4D targeted method was developed for the determination of 61 bioactive compounds in royal jelly (RJ) related to their health-promoting properties. The method, apart from high-resolution mass spectrometry, exploits the advantages of vacuum-insulated probe-heated electrospray ionization source (VIP-HESI), reducing thermal degradation, and trapped ion mobility spectrometry (TIMS), improving selectivity and compound identification. The optimization of VIP-HESI ionization parameters using experimental designs showed that the critical parameters were the capillary voltage as well as the probe gas flow rate and temperature. The LODs of the validated method ranged between 0.0013 and 0.090 μg g^-1, the recoveries between 80 and 109%, while %RSDs were below 10%. The method wa
