Analysis of Matrine Alkaloids in Human Urine by Hollow Fiber Liquid-phase Microextraction with High-performance Liquid Chromatography
A sensitive quantitative method for the determination of matrine alkaloids in human urine was developed based on hollow fiber liquid-phase microextraction (HF-LPME) combined with HPLC. The influence of the different factors on the HF-LPME efficiency including the pH and ion strength of the donar solution, the pH of the acceptor solution, stirring rate and extraction time were examined. The best...
متن کاملMicroextraction and Determination of Diclofenac in Biological Samples using Hollow Fiber Liquid Phase Microextraction Technique Coupled with HPLC-UV
In this study, hollow fiber liquid phase microextraction (HF-LPME) coupled with highperformanceliquid chromatography (HPLC) with UV detection was applied for preconcentrationand determination of Diclofenac sodium in biological fluids. Parameters affecting the extractionprocess including pH of donor phase and acceptor phase, type of extraction solvent, stirring rate,extraction time, and salt add...
متن کاملZnO polythiophene SBA-15 nanoparticles as a solid-phase microextraction fiber for fast determination essential oils of Matricaria chamomilla
The objective of this study is determination the volatile compounds of Matricaria chamomilla of an inorganic–organic hybrid material based on ZnO nanoparticles anchored to a composite made from polythiophene and hexagonally ordered silica (ZnO/PT/SBA-15) as a solid-phase fiber microextraction (SPME). Microextraction techniques with nanoparticles ZnO/PT/SBA-15 resulted in a more efficient analyt...
متن کاملDevelopment of miniaturized hollow-fiber assisted liquid-phase microextraction with in situ acyl derivatization followed by GC-MS for the determination of benzophenones in human urine samples.
A simple and highly sensitive method that involves miniaturized hollow fiber assisted liquid-phase microextraction (HF-LPME) with in situ acyl derivatization and GC-MS was developed for the determination of benzophenone (BP) and related compounds in human urine samples. The limits of detection (S/N = 3) and quantification (S/N > 10) of BPs in human urine samples are 0.01 to 0.05 and 0.05 to 0.2...
متن کاملhollow fiber-based liquid phase microextraction combined with high-performance liquid chromatography for extraction and determination of loratadine in human plasma
the applicability of hollow fiber-based liquid phase microextraction (hf-lpme) was evaluated for the extraction and preconcentration of loratadine prior to determination by hplc. in order to obtain high extraction recovery, the parameters affecting the hf-lpme including type of organic phase, ph of the source and receiving phases, stirring rate, extraction time and salt addition were studied an...
