AB  - 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 ether-cyclohexane (5:3:2, v/v/v) solvent system was used for quantitative evaluation of chromatograms. The chromatographic zones corresponding to the spots of DEET and DMP on the silica gel plates were scanned in the reflectance/absorbance mode at 230 nm. The method was found to be reproducible and convenient for the quantitative analysis of DEET and DMF in raw material and cosmetic products.

AB  - A sensitive spectrophotometric method for the determination of bifonazole is described. Bifonazole was treated with bromphenol blue (BPB) in the presence of citrate buffer (pH 2.5; μ = 0.23). The formed ion-pair complex was extracted with chloroform. By using spectrophotometric measurements, Job's and Bent-French's methods, it was found that bifonazole and BPB formed an ion-pair complex with the absorption maximum at 414 nm (molecular ratio of bifonazole BPB = 1:2) and molar absorptivity 2.23 x 104 L mol-1 cm-1. Beer's law was obeyed up to 2.5 μg ml-1. The proposed method was applied for determination of bifonazole in pharmaceutical formulations. Statistical analysis of the results obtained showed that the proposed method has good reproducibility and precision.

AB  - A simple, rapid and reproducible fluorodensitometric method for the determination of conjugated estrogens has been developed. The proposed procedure includes the following steps: extraction, hydrolysis of sodium sulphate esters of estrone, equilin, equilenin and their 17-α-hydroxy derivatives, separation of the liberated 3-phenolic steroids and in situ measurement of fluorescence. The fluorescence emission was measured after spraying the spots of estrone and estradiol with 2,4-dinitrophenylhydrazine in sulphuric acid-ethanol medium and equilin and 17-α-dihydroequilin with phosphoric acid and sodium hydroxide solution, respectively. Equilenin and 17-α-dihydroequilenin were determined by measuring the native fluorescence. The method applied to the determination of raw material and tablets provided results which agreed well with the stated content and the requirements of USP XXI for conjugated estrogens.
