1 publicationAnti-Microbial Activity of Ferulic Acid Isolated From Cansjera Rheedii J.Gmelin (Opiliaceae)
Ferulic acid (4-hydroxy-3-methoxy cinnamic acid) isolated from the aerial parts of Cansjera rheedii J.Gmelin (Opiliaceae) has been tested for its antimicrobial activity The antimicrobial activity have been studied with ferulic acid against Stapylococcus aureus, Bacillus substilis, Escherichia coli, Salmonilla paratyphi, Candida albicans, Aspergillus fumigates which gave significant results of activity against Ciprofloxacin & Clotrimazole as standards.Â

1 publicationCharacterization Of Some Birds Egg And Their Cholestrol Estimation
A Study was conducted on varieties of birds eggs  there by extracting yolk and albumin. The eggs of java, quail, hen and love bird were chosen for the study and they were procured from commercial farms, bird markets and breeding places. The  physical characteristics such as weight, shape, size and colour of the egg were analyzed. The yolk and their albumin were separated and incubated at 500c for a period of 48 hours and their moisture loss was calculated. Similarly, the total cholesterol estimated found high in the hens egg followed by love birds, were least in the quail and java egg. Thus a conclusion was drawn that eggs of different birds are almost same colour but different in size, shape and possess different ratio of yolk and albumin.

1 publicationDEVELOPMENT AND VALIDATION OF DERIVATIVE UV-SPECTROPHOTOMETRIC METHODS FOR QUANTITATIVE ESTIMATION OF ILOPERIDONE IN BULK AND PHARMACEUTICAL DOSAGE FORM
 First and second order derivative UV-Spectrophotometric methods have been developed and validated for the estimation of Iloperidone in bulk and its tablet formulations. The solutions of standard and sample were prepared in methanol. The Iloperidone solution was showed the maximum absorbance at 262nm and 248nm for the first and second order UV-Spectrophotometric methods respectively. Beer’s law was obeyed in the concentration range of 4- 12 μg / ml with r2 value 0.999 for both the methods. These methods were tested and validated for various parameters according to ICH guidelines. The precision expressed as relative standard deviation and was found within the range of 0.13 % to 1.7 % for the both methods. Limit of detection was 0.0133 μg/ml (first order), 0.0216 μg/ml (second order) and limit of quantification was found to be 0.0403 μg/ml (first order), 0.0657 μg/ml (second order). Recovery of Iloperidone was found to be within the range of 99.51 – 100.16 % for the two methods. The proposed methods were successfully applied for the determination of Iloperidone in tablet formulations. In addition, the proposed methods are simple, easy to apply, low cost, and requires relatively inexpensive instruments. Â
