Two new simple, selective, sensitive and economical methods (A and B) have been developed for the analysis of mefloquine hydrochloride in pure and pharmaceutical dosage form. The methods were based on ion-pair complexation between drug and dyes like metanil yellow and bromophenol blue at an optimum pH 2.8. The colored chromogens were measured at 410 nm (λmax) for method A and 415 nm (λmax) for ...

The aim of the work was to develop a simple, economical and eco-friendly spectrophotometric method for determining metoprolol tartrate in tablets based on reaction with bromophenol blue (BPB).
 Material methods: A double–beam Shimadzu UV-Visible spectrophotometer, spectral bandwidth 1 nm wavelength accuracy ±0.5 nm, Model –UV 1800 (Japan), Software UV-Probe 2.62, pair cm matched quartz cel...

The fabrication of metal oxide nanofibers using (titanium (IV) isopropoxide) and (tin tert-butoxide) weight ratio 1:1 precursor in presence poly (vinyl pyrrolidone) as a binder well-known electrospinning technique is reported. average diameter TiO2, SnO2, composite TiO2-SnO2 were found to be the range 75–110 nm. characterized thermogravimetric analysis (TGA) understand polymer evaporation tempe...

Laccase production by Pycnoporus sanguineus RP15 grown in wheat bran and corncob under solid-state fermentation was optimized by response surface methodology using a Central Composite Rotational Design. A laccase (Lacps1) was purified and characterized and the potential of the pure Lacps1 and the crude culture extract for synthetic dye decolorization was evaluated. At optimal conditions (eight ...

Amine-based volatile compounds released bymicroorganisms offer an alternative diagnostic approach for the identification of foodborne pathogens. Our objective has been to solvent cast cellulose acetatemembranes to immobilise dyes and to use the resultant membranes as a plastic device to discriminate between different types of amines (triethylamine, isobutylamine, isopentylamine). The plastic de...

AIM The aim was to develop an indicator sensor for real-time monitoring of meat quality and to compare the response of indicator sensor with meat quality parameters at ambient temperature. MATERIALS AND METHODS Indicator sensor was prepared using bromophenol blue (1% w/v) as indicator solution and filter paper as indicator carrier. Indicator sensor was fabricated by coating indicator solution...

PURPOSE To investigate the in vitro effect of vital dyes on toxicity and apoptosis in a human retinal pigment epithelial cell line. METHODS ARPE-19 cells were exposed to brilliant blue (BBG), Evans Blue (EB), bromophenol blue (BroB), indocyanine green (ICG), infracyanine green (IfCG), light green (LG), fast green (FG), indigo carmine (IC) and Congo red (CR). Balanced salt solution was used as...
