HPLC Determination of Artemisinin in Artemisia Annua L.
In an article recently published in Analytica Chimica Acta, researchers developed a procedure for the determination of artemisinin in A. annua using high performance liquid chromatography (HPLC) with evaporative light scattering detection (ELSD) in couple with microwave-assisted extraction (MAE) as an efficient sample preparation technique. Afterwards, method validation system for HPLC?ELSD analysis was developed.
In an article recently published in Analytica Chimica Acta, researchers developed a procedure for the determination of artemisinin in A. annua using high performance liquid chromatography (HPLC) with evaporative light scattering detection (ELSD) in couple with microwave-assisted extraction (MAE) as an efficient sample preparation technique. Afterwards, method validation system for HPLC–ELSD analysis was developed. Limit of detection was less than 40 É g mL-1 and limit of quantification was less than 100 É gmL-1.
Accuracy validation showed that average recovery was between 98.23% and 104.97%. The developed analytical procedure was successfully applied to determine the contents of artemisinin in the different parts of A. annua plants.
Extracting Estrogenic Hormones Using Rotating Disk and Modified Clays
April 14th 2025University of Caldas and University of Chile researchers extracted estrogenic hormones from wastewater samples using rotating disk sorption extraction. After extraction, the concentrated analytes were measured using liquid chromatography coupled with photodiode array detection (HPLC-PDA).
Polysorbate Quantification and Degradation Analysis via LC and Charged Aerosol Detection
April 9th 2025Scientists from ThermoFisher Scientific published a review article in the Journal of Chromatography A that provided an overview of HPLC analysis using charged aerosol detection can help with polysorbate quantification.
