Quantitative analysis of sulpiride and impurities of 2-aminomethyl-1-ethylpyrrolidine and methyl-5-sulphamoyl-2-methoxybenzoate in pharmaceuticals by high-performance thin-layer chromatography and scanning densitometry
(AOAC International, Gaithersburg, 1999)
A simple and reliable thin-layer chromatographic method for determining sulpiride and impurities of 2-aminomethyl-1-ethylpyrrolidine and methyl-5-sulphamoyl-2-methoxybenzoate was developed and validated. A methylene ...
Comparison of spectrophotometric and UV-densitometric methods for the determination of celiprolol hydrochloride in tablets
(Wiley, 1998)
Spectrophotometric and UV-densitometric methods for the determination of celiprolol hydrochloride in tablet formulations were compared. Celiprolol hydrochloride and benzylorange react in a 1:1 ratio in the presence of ...
Quantity and composition of essential oil of the wild plant Nepeta nuda L. from Yugoslavia
(Journal of Essential Oil Research, 1998)
The aerial parts of the wild plant Nepeta nuda L. collected in Serbia and the Durmitor region contained respectively 0.67–0.70% and 0.4% oil. Each oil was analyzed by GC and GC/MS. The main constituent was 1,8-cineole; ...
Effects of flavonoids on plasma coagulation tested in vitro by "screening tests"
(Društvo medicinskih biohemičara Srbije i Crne Gore, Beograd i Univerzitet u Beogradu - Farmaceutski fakultet, Beograd, 1999)
The effects of four flavonoids: rutin, quercetin, morin and hesperidin on plasma coagulation has been examined by measuring aPTT, TT and PT. It is found that water solution of these flavonoids shows no effects in the ...
Spectrophotometric and electrochemical study of protolytic equilibria of some oximes-acetylcholinesterase reactivators
(Pergamon-Elsevier Science Ltd, Oxford, 1999)
Newly synthesized oximes, mono and bis imidazole derivatives, which promise to be more effective acetylcholinesterase reactivators than standard antidotes used, were investigated by spectrophotometric and electrochemical ...
Simple and rapid method for the measurement of nitrite and nitrate in human plasma and cerebrospinal fluid by capillary electrophoresis
(Elsevier Science BV, Amsterdam, 1999)
Nitrite and nitrate levels in physiological fluids are commonly used as an index of nitric oxide production. We developed simple and rapid method for the determination of these anions by capillary zone electrophoresis ...
Determination of some insect repellents in cosmetic products by high-performance thin-layer chromatography
(Elsevier Science BV, Amsterdam, 1999)
A simple and reliable thin-layer chromatographic method for the determination of N,N-diethyl-m-toluamide (DEET) and dimethyl phthalate (DMP) in raw material and cosmetic products was developed and validated. A benzene-diethyl ...
New Tc-99m-diiodine substituted IDA derivative (DIIODIDA) for hepatobiliary imaging
(SpringerElsevier Science B. V., Amsterdam, 1999)
A new diiodine substituted LDA derivative, 2,4-diiodine-6-methyl IDA (DIIODIDA) was synthesized and labeled with Tc-99m. It was established that Tc-99m-DIIODIDA had high radiochemical purity. Biodistribution and influence ...
