Liquid Chromatographic

Abstract A gas-liquid chromatographic (GLC) method is described for the quantitative determination of /V-octylbicycloheptene dicarboximide (MGK 264 synergist) in technical materials and in various formulations. The samples are diluted with acetone and analyzed by GLC, using a flame ionization detector and a column packed with OV-1 on Chromosorb W (HP). Preliminary work indicates that satisfactory results can be obtained with the technical material and several different formulations.

Abstract Accurate methods are described for the qualitative and quantitative determination of medazepam, diazepam, and nitrazepam in 5 ml of whole blood. Medazepam and diazepam are analyzed intact and nitrazepam is chromatographed as its trimethylsilyl derivative by flame-ionization gas-chromatography on "1% OV-17." A supplementary column of "2% OV-1" is used to separate nitrazepam TMS from diazepam when both are present in the same extract. Essential data given include the percentage recovery of medazepam, and the flame-ionization detector responses of diazepam and silylated nitrazepam relative to medazepam, calculated after extraction from blood and gas-chromatographic analysis. Chromatograms are illustrated of extracts of blood taken from patients on medazepam and diazepam therapy and from a patient who had taken an overdose of nitrazepam.

There is studied chemical composition of neutral and polar lipids of the seeds of: Medicago sativa, Amaranlhus cmentus and Amaranthus retroflexus growing in Georgia. The composition of free fatty acids was determined with help GLC and HPLC. There is determined class and fatty acidal composition of them, qualitative and quantitative determination of phospholipids is carried. There is elaborated various medicinal forms from Medicago sativat.
