HPTLC assay of cephalexin and cefaclor in pharmaceuticals
(John Wiley and Sons Ltd, 1998)
A simple and reliable HPTLC method for the simultaneous determination of cephalexin and cefaclor is developed and validated. The methanol-ethyl acetate-acetone-water (5:2.5:2.5:1.5 v/v/v/v) solvent system is used for the ...

Aromatic Plants of Yugoslavia. I. Chemical Composition of Oils of Achillea millefolium L. ssp. pannonica (Scheele) Hayak, A. crithmifolia W. et K., A. serbica Nym. and A. tanacetifolia All.
(Allured Publishing Corp., 1999)
We used GC/MS to determine the chemical composition of the essential oils of
wild Achillea plants native to Yugoslavia: Achillea millefolium L. ssp. pannonica
(Scheele) Hayak, A. crithmifolta W. et K., A. serbica Nym. ...
Flavonoid and phenolic acid patterns in seven Hieracium species
(Biochemical Systematics and Ecology, 1999)
We propose a new model for landslide dynamics under the assumption of a delay failure mechanism. Delay failure is simulated as a delayed interaction between adjacent blocks, which mimics the relationship between the ...

Densitometric determination of urinary 4-hydroxy-3-methoxymandelic acid (vanillylmandelic acid)
(Clinical Chemistry, 1993)
We propose a simple and precise densitometric method for measuring vanillylmandelic acid (VMA). The method comprises direct urine application, thin-layer chromatographic (TLC) separation, postchromatographic derivatization, ...
A spectrophotometric method for the determination of equilibrium constants of the reversible 1,4-benzodiazepine ring-opening reaction
(Journal of the Chemical Society, Perkin Transactions 2, 1994)
A general spectrophotometric method is proposed for the quantitative investigation of the hydrolysis of 1,4-benzodiazepines which, under the effect of nucleophilic hydration, undergo reversible cleavage of the 4,5-azomethine ...
Potentiometric determination of furosemide
(Acta Pharmaceutica Jugoslavica, 1990)
A simple method is presented for the potentiometric determination of small quantities of furosemide in a pure state and in pharmaceutical formulations, using 0.1 mol l-1 chloramine-T as titrant. In potentiometric titrations ...
