Use of ANN modelling in structure-retention relationships of diuretics in RP-HPLC
(Pergamon-Elsevier Science Ltd, Oxford, 1999)
Structure-retention relationship study, conducted by RP-HPLC, was used to investigate physical chemical parameters related to the RP retention times of amiloride, hydrochlorothiazide and methyldopa in order to predict the ...
Spectrophotometric study of diclofenac-Fe(III) complex
(Pergamon-Elsevier Science Ltd, Oxford, 1997)
A multifactor optimisation technique is successfully applied to develop a new spectrophotometric method in which diclofenac sodium is analysed and determined as it's Fe(III) complex. The effect of simultaneously varying ...
Densitometric determination of conjugated oestrogens in the raw material and in pharmaceutical preparations
(Journal of Pharmaceutical and Biomedical Analysis, 1990)
A densitometric method for determination of complex mixtures of conjugated oestrogens in raw material and tablets was developed. The proposed procedure comprised hydrolysis of sodium sulphate esters of oestrone, equilin, ...
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 ...

The objective of this investigation was to develop a HPTLC method for the determination of ceftriaxone, cefixime and cefotaxime, cephalosporins widely used in clinical practice, High performance TLC of cephalosporins was ...
Determination of fleroxacin in human serum and in dosage forms by derivative UV spectrophotometry
(Pergamon-Elsevier Science Ltd, Oxford, 1998)
Densitometric determination of metoprolol tartrate in pharmaceutical dosage forms
(Pergamon-Elsevier Science Ltd, Oxford, 1997)
This paper describes a simple densitometric method for the determination of metroprolol tartrate in tablets and ampoules. After separation on silica gel GF254 plates, using acetone-methanol-triethylamine as the mobile phase ...
