AIM to evaluate the presence of preservatives, dyes, sweeteners and flavouring substances in 73 pharmaceutical preparations of 35 medicines for oral administration, according to drug labeling information about the excipients. METHODS 35 medications were selected, both over-the-counter and prescription drugs, marketed in Brazil. The sample included: analgesic/antipyretic, antimicrobial, mucore...

Food colors have been in use since long to restore the original food appearance. The azo dyes tartrazine, metanil yellow and sunset yellow are used in different food items for coloring purpose. The great increase in the use of these food colors led to cause adverse effects in different body organs. A blend of two or more dyes may produce an altogether different response. So the present study wa...

We proposed a simple and effective method, by coupling ionic liquid-based aqueous two-phase systems (IL-ATPSs) with high performance liquid chromatography (HPLC), for the analysis of determining tartrazine and sunset yellow in food samples. Under the optimized conditions, IL-ATPSs generated an extraction efficiency of 99% for both analytes, which could then be directly analyzed by HPLC without ...

OBJECTIVE Certain dietary constituents can induce toxicity and play a critical role in the development of several hepatic disorders. Tartrazine, metanil yellow and sunset yellow are widely used azo dyes in food products, so the present study is aimed to investigate the food color induced hepatotoxicity in Swiss albino rats. MATERIALS AND METHODS Swiss albino rats were divided into four groups...

Sunset Yellow (SY) is an organic azo dye that used extensively as a coloring agent in many industries, such cosmetics, pharmaceuticals ,and foodstuffs. Many studies have conflicting results about the genotoxicity effect of SY. Thus, purpose this study was to provide additional data concerning SY human lymphocytes by using chromosomal aberrations (CAs) and sister chromatid exchanges (SCEs) assay...

The corrosion inhibition properties of some organic dyes, namely Sunset Yellow (SS), Amaranth (AM), Allura Red (AR), Tartrazine (TZ) and Fast Green (FG), for mild steel corrosion in 0.5 M HCl solution, were investigated using gravimetric, potentiodynamic polarization techniques and quantum chemical calculations. The results showed that the studied dyes are good corrosion inhibitors with enhance...
