Determination of pesticide residues in ginseng by dispersive liquid-liquid microextraction and ultra high performance liquid chromatography-tandem mass spectrometry.

Abstract

A procedure involving acetonitrile-based extraction combined with dispersive liquid-liquid microextraction (DLLME) and detection by ultra high performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS) was used for determination of 39 pesticides in ginseng. The extraction of pesticide residues in ginseng was performed with acetonitrile… (More)
