Spectrophotometric determination of hesperidin by Al(III)-hesperidin complex in water-methanol solution
(Marcel Dekker Inc, New York, 1997)
The composition and the stability constant of the Al(III)-hesperidin complex were determined by suitable spectrophotometric methods and pH measurements. The formation of the complex, whose concentration stability constant ...
High performance liquid chromatographic determination of clindamycin in pharmaceutical formulations
(Srpsko hemijsko društvo, Beograd, 1997)
A specific and simple HPLC procedure was developed, su table for the determination of dindamycin hydrochloride monohydrate (CLHC) and clindamycin 2-dihydrogenphosphate (CLPH) in pharmaceutical formulations. Rp-HPLC analysis ...
Compared effects of high oral Mg supplements and of EDTA chelating agent on chronic lead intoxication in rabbits
(John Libbey Eurotext, 1997)
Our previous experiments showed that excessive oral Mg intake has beneficial effects in chronic Pb poisoning, inducing decrease of Pb body burden and its increased elimination via urine. The aim of this work was to investigate ...
Quantitative determination of neutral animal lipids by planar chromatography with a new detection method
(Akademiai Kiado Zrt, Budapest, 1997)
Variability of the essential oil composition of the species Satureja montana L. (Lamiaceae)
(Journal of Essential Oil Research, 1997)
The chemical composition of the oils of one population of Satureja montana L. subsp. pisidica (Wettst.) Silic and two populations of S. montana subsp. montana were investigated on the intrapopulational and interpopulational ...
Determination of midazolam in pharmaceutical dosage forms by second-order derivative ultraviolet spectrophotometry
(Srpsko hemijsko društvo, Beograd, 1997)
A second-order derivative ultraviolet spectroscopic method for the determination of midazolam in the presence of maleic acid is described. The assays were carried out in borate buffer (pH 9.2) at a wavelength of 222 nm, ...
Flavonoids from the herb resin of Achillea atrata L. Subspec, multifida (DC.) HEIM
(Medical Information Center, 1997)
Two flavonoid aglycones were isolated from the resin obtained by washing dry herb of Achillea atrata subspec. multifida with chloroform. The spectral characteristics (UV, MS, 1 H NMR) of these aglycones indicated that they ...
The influence of Eudragit type on the dissolution rate of acetylsalicylic acid from matrix tablets
(Magyar Gyogyszereszeti Tarsasag, 1997)
The effect of four Eudragits used as matrix substances on the physical characteristics of tablets and on the dissolution rate of acetylsalicylic acid has been investigated. The concentration of matrix substance necessary ...
UV spectrophotometric microdetermination of L-DOPA based on complex formation with copper(II)ion
(Marcel Dekker Inc, New York, 1997)
The UV spectrophotometric investigations obtained for the reaction between L-DOPA and copper(II)ion contribute to the clarification of equilibrium conditions of the complex formation both in the excess of metal ion and ...
