Simultaneous determination of mycotoxins in biological fluids by LC-MS/MS.
We report a single, reliable, non-invasive analytical method for monitoring the fetal level of exposure to different mycotoxins. We assessed by tandem mass spectrometry levels up to 200 nanog/l for ochratoxin A and 500 nanog/l for aflatoxins in sample of serum (n= 71), urine (n= 18) and amniotic fluid (n= 21) of pregnant women. Aflatoxin G1 was present in one sample of serum (3.48 microg/l) and...
متن کاملSimultaneous Determination of Atorvastatin and Aspirin in Human Plasma by LC–MS/MS: Its Pharmacokinetic Application
A simple, rapid, and sensitive liquid chromatography tandem mass spectro-metric (LC-MS/MS) assay method has been developed and fully validated for the simultaneous quantification of atorvastatin and aspirin in human plasma using a polarity switch. Proguanil and furosemide were used as the internal standards for the quantification of atorvastatin and aspirin, respectively. The analytes were extr...
متن کاملSimultaneous Determination of Multi-Mycotoxins in Cereal Grains Collected from South Korea by LC/MS/MS
An improved analytical method compared with conventional ones was developed for simultaneous determination of 13 mycotoxins (deoxynivalenol, nivalenol, 3-acetylnivalenol, aflatoxin B₁, aflatoxin B₂, aflatoxin G₁, aflatoxin G₂, fumonisin B₁, fumonisin B₂, T-2, HT-2, zearalenone, and ochratoxin A) in cereal grains by liquid chromatography-tandem mass spectrometry (LC/MS/MS) after a single immunoa...
متن کاملSimultaneous determination of 11 major components in Palmul-tang by HPLC-DAD and LC-MS-MS.
Palmul-tang, a traditional herbal medicine, is composed of eight herbs (Ginseng radix, Glycyrrhizae radix, Hoelen, Atractylodis rhizoma, Angelicae gigantis radix, Cnidii rhizoma, Paeoniae radix and Rehmanniae radix) and exhibits various bioactivities, including antiallergic and antitumor effects. In this study, an effective, reliable and accurate high-performance liquid chromatography method ha...
متن کاملSimultaneous Determination of Nitroimidazoles and Quinolones in Honey by Modified QuEChERS and LC-MS/MS Analysis
This study reports an analytical method for the determination of nitroimidazole and quinolones in honey using liquid chromatography-tandem mass spectrometry (LC-MS/MS). A modified QuEChERS methodology was used to extract the analytes and determine veterinary drugs in honey by LC-MS/MS. The linear regression was excellent at the concentration levels of 1-100 ng/mL in the solution standard curve ...
