An efficient and selective pretreatment method of one-step hydrophilic interaction chromatography-based solid phase extraction (HILIC SPE) was developed using silica as the sorbent to quickly and sensitively detect endogenous ABA and its five catabolites in fresh Oryza sativa tissues. The extracted analytes were sensitively quantified with ultra high performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS). Under the optimized conditions, good linearity of the developed analytical method was obtained in the range of 0.2-1000 ng/mL with linear correlation coefficients ( r) greater than 0.9987. The limits of detection (LODs, signal/noise = 3) ranged from 0.01 to 0.74 ng/mL. The relative recoveries were between 83.3% and 112.0% with the relative standard deviations (RSDs) ranging from 0.5 to 15.0%. Using the proposed method, the concentration variations of ABA and its catabolites were monitored in the salt-stressed rice tissues.

D052616 Solid Phase Extraction An extraction method that separates analytes using a solid phase and a liquid phase. It is used for preparative sample cleanup before analysis by CHROMATOGRAPHY and other analytical methods. Extraction, Solid Phase,Extractions, Solid Phase,Solid Phase Extractions
D053719 Tandem Mass Spectrometry A mass spectrometry technique using two (MS/MS) or more mass analyzers. With two in tandem, the precursor ions are mass-selected by a first mass analyzer, and focused into a collision region where they are then fragmented into product ions which are then characterized by a second mass analyzer. A variety of techniques are used to separate the compounds, ionize them, and introduce them to the first mass analyzer. For example, for in GC-MS/MS, GAS CHROMATOGRAPHY-MASS SPECTROMETRY is involved in separating relatively small compounds by GAS CHROMATOGRAPHY prior to injecting them into an ionization chamber for the mass selection.
