A Simple, Rapid Method for Paper Chromatography of Barbiturates.
Barbiturates are extracted quantitatively into ethyl ether from biologic fluids buffered to pH 6. A measured portion of the ether extract is then impinged to dryness and the residue spotted on Whatman No. 2 paper that has been previously dipped in alkali and dried. The paper is developed by descending chromatography with chloroform saturated with water. The barbiturate may then be located and a...
متن کاملA rapid micro-method for the screening and measurement of barbiturates and related compounds in plasma by gas-liquid chromatography.
A rapid gas-chromatographic method has been developed for the determination of butobarbitone, amylobarbitone, hexabarbitone, pentobarbitone, quinalbarbitone, phenobarbitone glutethimide, and methaqualone in ;finger-prick' samples of plasma. This has been applied to the analysis of some of these drugs in plasma taken from patients after therapeutic dosage and over-dosage.
متن کاملRapid screening method for detection of deoxynivalenol.
A rapid method for detecting deoxynivalenol (DON), also known as vomitoxin, was developed. DON was extracted from grains and other samples with acetonitrile-4% potassium chloride solution (9 + 1). Impurities that would interfere with detection were removed on a C18 silica gel reverse phase column. Water was removed from eluates on a hydrophilic matrix column. DON was detected by thin layer chro...
متن کاملEmergency screening of urine, plasma, or gastric contents for barbiturates.
THERE IS AN EVER-increasing need for a rapid method of screening for barbiturates in the laboratory. Although the ultraviolet methods (1, ) are the most accurate, they require 0.5 to 2 h of technician time and therefore are hardly ideal for emergency-room use. Some methods have been published which depend on the complexing reaction of barbiturates in an organic solvent with a mercury salt in an...
متن کاملA REPORT OF RAPID AND EFFICIENT METHOD FOR MITOCHONDRIAL DNA
Based on the similarity of prokaryotic DNA to that of mitochondrial DNA, a rapid and efficient method for DNA purification from mitochondrial extracts obtained from different sources, was carried out based on the modification method described by Marmur (1983) which resulted in a high degree of purity (A260/A280=2). In addition we have applied the same technique for the first time to purify...
