UV- Spectrophotometric determination of Ceftazidime in pure and pharmaceutical formulation

A simple sensitive spectrophotometric method in UV region has been developed for the determination of Ceftazidime in bulk dosage form. The solution of ceftazidime in 0.1N HCl shows maximum absorbance at 261nm, beer’s law was obeyed in the concentration range of 2-10 µg ml-1. The absorbance was found to increase linearly with increasing concentration of ceftazidime, which is corroborated by the calculated correlation coefficient value of 0.9981. The slope and intercept of the equation of the regression line are 0.0465 and 0.0007 respectively. The analysis were validated statistically and its recovery studies result of percentage shows that the method was not affected by the presence of excepients which proves suitability of the developed method for the routine estimation of ceftazidime bulk and solid dosage form. This method were extended to pharmaceutical formulations and there no interference from excepients and diluents. The proposed methods are economical and sensitive for the estimation of ceftazidime in bulk dosage form.

Quantitative analysis of civetone and normuscone in secretion from Viverricula indica and in aromatic remedies by gas chromatography-mass spectrometry

Image
ABSTRACT : The quantitation of civetone and normuscone in small Indian civet (Viverricula indica Desmarest) secretion cultivated in Thailand was analyzed by gas chromatography- mass spectrometry (GC-MS). Three main chemical constituents of small Indian civet secretion were civetone, dihydrocivetone and normuscone. The contents of chemical constituents were different between male and female secretion. Civetone (23.6 ± 1.5 µg/mg of secretion) was a major chemical constituent in the female secretion while normuscone (52.1 ± 5.9 µg/mg of secretion) was a major in the male secretion. Both civetone and normuscone were found in civet fur but not in the feces. Aromatic remedies which claimed to use the small Indian civet secretion as an ingredient showed both civetone and normuscone. Linearity range of civetone was 0-50 µg/ml with a correlation coefficient of 0.9717, and of normuscone was 0-80 µg/ml with a correlation coefficient of 0.9965. The average recoveries were 97.3-98.0% in sec...

Antimicrobial activity of aqueous, ethanolic, methanolic, cyclohexanic extracts and essential oil of Nigella sativa seeds

Image
  ABSTRACT : Most of the bacterial pathogens are resistant to existing synthetic antibacterial agents demanding an increasing effort to seek effective phytochemicals as antibacterial agents against such pathogens. Nigella sativa L. (black cumin) seeds play an important role in folk medicine and some of its major constituents are reported to be pharmacologically active. In this present work, Nigellasativa seed extracts were obtained using maceration extraction by various solvents (water, ethanol, methanol, and cyclohexan). The antibacterial and antifungal effects of different extracts and essential oil of seeds were investigated by the agar diffusion method against two gram positive (Bacillus subtilis CIP52.62 ,Staphylococcus aureus CIP4.83) and three gram negative strains of bacteria (Escherichia coli CIP53.126 ,Pseudomonas aeroginosa CIP82.118, Salmonella abony CIP80.39) and one strain of fungi (Candida albicans CIP48.72). All the extracts and essential oil showed varying d...

A Validated specific Stability-indicating RP-HPLC method for Aripiprazole and its related substances

Image
ABSTRACT : A validated specific stability indicating reversed-phase liquid chromatographic method was developed for the quantitative determination of Aripiprazole and its related substances in bulk samples, pharmaceutical dosage forms in presence of degradation products. Forced degradation studies were performed on bulk sample of Aripiprazole as per ICH prescribed stress conditions using acid, base, oxidative, thermal stress and photolytic degradation to show the stability indicating power of the method. Significant degradation was observed during basic stress and no degradation was observed in other stress conditions. The chromatographic method was optimized using the samples generated from forced degradation studies and the impurity spiked with Aripiprazole. Good resolution between the peaks corresponds to impuritiy-1, degradation products from the analyte were achieved on YMC PACK C18 column using the mobile phase consists a mixture of Sodium dihydrogen Orthophosphate dehydra...
