Spectrophotometric assay of xanthine oxidase with 2,2'-azino-di(3-ethylbenzthiazoline-6-sulphonate) (ABTS) as chromogen
(Clinica Chimica Acta, 1987)
A new method for the determination of xanthine oxidase activity, based on the oxidation of 2, 2'-azino-di(3-ethylbenzthiazoline-6-sulphonate) (ABTS) by use of uricase and peroxidase, is described. The absorbance increase ...
Determination of acidic constants of some phenyl-hydroxyiminoethyl quinolinium compounds
(Springer-Verlag, 1986)
Mixed acidic constants (pK′a) of quinolinium oximes [1-(2-phenyl-2-hydroxyiminoethyl)-1-quinolinium chloride (F-1), 1-(2-phenyl-2-hydroxyiminoethyl)-1-isoquinolinium chloride (F-2), 1-(2-phenyl-2-hydroxyiminoethyl)-1-(4′ ...
Reduction and Determination of 1‐[2‐Phenyl‐2‐(hydroxyimino)‐ethyl]‐6‐methylquinolinium Chloride on the Dropping Mercury Electrode
(Archiv der Pharmazie, 1987)
The polarographic behavior of 1‐[2‐phenyl‐2‐(hydroxyimino)ethyl]‐6‐methylquinolinium chloride has been investigated. The pH of the Britton‐Robinson buffer, used as supporting electrolyte, influences the position of the ...
Some kinetic characteristics of erythrocyte alanine aminotransferase phenotypes
(Journal of Applied Biochemistry, 1985)
The activity of alanine aminotransferase (ALT) phenotypes was determined in 148 hemolysates of the Serbian population. The highest activity was obtained for phenotype ALT 1 (0.614 U/g Hb), intermediate for ALT 2-1 (0.475 ...
Spectrophotometric behaviour of quinolinium oxime-palladium(II) complexes
(Springer-Verlag, 1985)
It has been established that 1-(2-phenyl-2-hydroxyiminoethyl)-1-quinolinium chloride, 1-(2-phenyl-2-hydroxyiminoethyl)-1-isoqui-nolinium chloride, 1-(2-phenyl-2-hydroxyiminoethyl)-1-(4′-methyl)-quinolinium chloride and ...
Spectrophotometric determination of some theophylline derivatives
(Acta Pharmaceutica Jugoslavica, 1988)
A spectrophotometric method for the determination of 8-chlorotheophylline, diprophylline and oxyethyltheophylline, is presented. Spectrophotometric determinations were carried out in CH3OH, 0.5 mol dm-3 H2SO4 4.65 mol dm-3 ...
The comparison of the spectrodensitometric determination of theophylline to HPLC, RIA and EMIT procedures
(Acta Pharmaceutica Jugoslavica, 1986)
Coulometric determination of methimazole
(Pharmazie, 1987)
Spectrophotometric determination of obidoxime chloride as its Pd(II) complex in water and injections
(Journal of Pharmaceutical and Biomedical Analysis, 1987)
It has been established that obidoxime chloride reacts with palladium(II) chloride in the pH range 3.9-8.0 and forms a yellow water-soluble (1:1) complex with maximum absorbance at 355 nm. By applying the methods of Sommer, ...
