Matrix complete dissolution concatenated biochar magnetic solid-phase extraction of benzotriazole ultraviolet stabilizers in polyester fibers prior to UPLC-MS/MS analysis

Development of an ultra‐high‐performance liquid chromatography–tandem mass spectrometry method for the simultaneous determination of crassicauline A, fuziline, karacoline, and songorine in rat plasma and application in their pharmacokinetics

“…Compared with HPLC, the sensitivity of UPLC-MS/MS is much higher, and because it benefits from a low detection limit and low sample consumption, UPLC-MS/MS is widely used in pharmaceutical analysis for evaluating chemical composition (Lu et al, 2023;Wu et al, 2023;Zhang et al, 2023;Zhao et al, 2023), elucidating drug metabolism, and identifying impurities (Famiglini et al, 2021;Nasiri et al, 2021). Therefore, this study sought to establish a UPLC-MS/ MS method for measuring the concentrations of crassicauline A, fuziline, karacoline, and songorine in rat plasma.…”
