2D MOF@Fe₃O₄@rGO as magnetic solid-phase extraction and supercritical fluids chromatography-tandem mass spectrometry quantification of strigolactones stereoisomers in rice (Oryza sativa L.).

Strigolactones (SLs) are novel plant hormones that play crucial roles in regulating plant growth and development. The stereoisomers of SLs often exhibit distinct biological activities, making their chiral separation and analysis essential for understanding their regulatory roles in plant branching. This study focused on the chiral separation and characterization of SL stereoisomers, including GR24 (synthetic) and strigol (natural).

Distribution, migration patterns, and food chain human health risks of endocrine-disrupting chemicals in water, sediments, and fish in the Xiangjiang River.

Exposure to endocrine-disrupting chemicals (EDCs) in freshwater systems has garnered increasing attention. A comprehensive analysis of the migration patterns, bioaccumulation, and consumer health risk of EDCs along the Xiangjiang River due to fish consumption from the river ecosystem was provided. Twenty natural and synthetic target EDCs were detected and analyzed from the water, sediments, and fish samples collected along the Xiangjiang River.
