Inhibition of Corrosion of Aluminium in NaOH Solution by Leave Extract of Mesembryanthemum nodiflorum

 

Corrosion inhibition of aluminum in 1M NaOH solution by Mesembryanthemum nodiflorum leaves extract was investigated using the weight loss technique. A plant extract solution of 14 g/L at 50 oC was found to inhibit the corrosion of aluminum with an inhibition efficiency of 95.1%. The inhibition efficiency was found to increase with increasing the concentration of the plant extract at 50 oC. Different adsorption isotherms, Langmuir and Temkin, were tested to investigate the nature of adsorption.

Uncovering counterfeit Viagra and Cialis using the portable NIR and the UV-Visible spectroscopy coupled with multivariate data analysis (a preliminary study)

In this study, two of the most common drugs (Cialis® and Viagra®) that are subjected to adulteration were investigated. The investigation involved examining the above drugs using both portable NIR and UV-Visible spectroscopy. The obtained spectral data were analyzed using multivariate chemometric methods such as Principal Components Analysis (PCA) and Cluster Analysis (CA). Discriminating between the original and the counterfeit drugs was successfully demonstrated with no or little chemical pretreatment. Detection of counterfeit drugs from different sources was also possible.

Green synthesis, crystal structure and bioactivity of C-(p-substitutedphenyl)calix[4]resorcinarenes-DMSO inclusion complexes

 

The solid state structures of the newly prepared C-(p-fluorophenyl)-calix[4]resorcinarene-DMSO and C-(p-chlorophenyl)calix[4]resorcinarene-DMSO inclusion complexes were determined by single-crystal X-ray diffraction and found to form different structural conformations; chair (C2h) and boat (C2v), respectively. The synthesized C-(p-substitutedphenyl)calix[4]resorcinarene hosts inhibited the growth of Gram-positive bacteria with the C-(p-bromophenyl)calix[4]resorcinarene derivative being the most potent agent (MIC) (15.6-125 μg/ml).

Development and Validation of HPLC Method for Simultaneous quantification of Prifinium Bromide/Paracetamol combination in Pharmaceutical Formulations

A simple, rapid, accurate and precise HPLC method was developed and validated for the simultaneous quantification of prifinium bromide and paracetamol combination in pharmaceutical dosage form.  The separation was achieved on a normal phase-nitrile (CN) column.  The mobile phase consisted of 30 mM ammonium acetate buffer–acetonirtile (50%:50%, v/v) at pH = 6.5.  The UV detection was carried out at a wavelength of 254 nm.  A linear response was observed over a concentration range 3–50 μg/mL for prifinium bromide and paracetamol.  The limit of detection for prifinium bromide was 0.75 μg/mL and its limit of quantification was 2.30 μg/mL. For paracetamol, the limit of detection was 0.64 μg/mL while its limit of quantification was 1.60 μg/mL.  The method was validated for linearity, accuracy, precision and robustness.  The validated method was applied to the analysis of prifinium bromide and paracetamol in commercial Riabal®Compound tablets.
