24 Jan 2020 Compared with traditional HPLC technology, which remains constant over a wider linear range, ultra-performance liquid chromatography (UPLC)

LC-MS-QTOF testing. A LC-MS-QTOF system was chosen to analyze samples following Lawal et al. (2016) with some modifications. By dissolving about 2 mg of each extract in 80% v/v ethanol, the sample aliquots were preapred. Accurately, 200 µL of the sample aliquot was filtered using microfilter and transferred into a glass vial.

The 2- and 3-hydroxyadipic acid isomers could not be resolved due to identical retention times and were therefore analyzed as one combined signal. Adipic acid and 3-methylglutaric acid have the same mass and com- 2019-03-30 · LC-MS/QTOF identification of phytochemicals and the effects of solvents on phenolic constituents and antioxidant activity of baobab (Adansonia digitata) fruit pulp 1. Introduction Baobab ( Adansonia digitata L.) is a big iconic tree belonging to the Bombaceae family and Malvales 2. Materials and Quantitative capability of LC-QTOF-MS/MS working in simultaneous full scan MS/MS was also evaluated by five European Proficiency Test samples. 2.1. Sample extraction The buffer citrate QuEChERS method was applied to the selected matrices.
