Measurement of indolebutyric Acid in plant tissues by isotope dilution gas chromatography-mass spectrometry analysis.
An internal standard, [(13)C][indole-2]-indole-3-butyric acid, was synthesized from indole-2[(13)C] and was shown to be effective for the quantitative determination of indole-3-butyric acid from plant tissue. When this standard was used along with [(13)C(6)]indole-3-acetic acid, both indolic auxins could be quantified from the same tobacco (Nicotiana tabacam) leaf sample by isotope dilution ana...
متن کاملMeasurement of Serum 17α-hydroxyprogesterone in Newborn Infants by Stable Isotope Dilution—Gas Chromatography/Mass Spectrometry
Immunochemical measurement of serum 17α-hydroxyprogesterone (17OHP), the most important parameter for diagnosis of classical 21-hydroxylase deficiency (21OHD) in newborn infants, is known to be inaccurate due to the cross-reactivity of antibodies with a large quantity of fetal adrenal steroids. The aims of this study were 1) to establish reference values for the serum 17OHP level in Japanese ne...
متن کاملAnalysis of fatty acid composition of Withania coagulans fruits by gas chromatography/mass spectrometry
Background and objectives: Withania coagulans Dunal (Solanaceae) fruits are recommended to treat asthma, dyspepsia, biliousness, flatulent colic, liver complaints, intestinal infections, strangury, wounds and as diuretic, emetic and sedative agent in Indian traditional system of medicine.

متن کاملAnalysis of N-nitrosamines in water by isotope dilution gas chromatography-electron ionisation tandem mass spectrometry.
A method has been developed for the determination of eight N-nitrosamines in drinking water and treated municipal effluent. The method uses solid phase extraction (SPE), gas chromatography (GC) and analysis by tandem mass spectrometry (MS-MS) with electron ionization (EI). The target compounds are N-nitrosodimethylamine (NDMA), N-nitrosomethyethylamine (NMEA), N-nitrosodiethylamine NDEA), N-nit...
متن کاملStable-isotope dilution gas chromatography-mass spectrometric measurement of 3-hydroxyglutaric acid, glutaric acid and related
We developed a simple and sensitive stable-isotope dilution method for the quantification of 3-hydroxyglutaric acid (3HGA) and glutaric acid (GA) in body fluids. In our method, tertbutyldimethylsilyl derivatives of 3HGA and GA were measured with a conventional electron-impact ionization mode in gas chromatography-mass spectrometry. The control values for 3HGA in nmol/ml were 0.15 ± 0.08 (serum;...
