EVALUATION OF PRESERVATIVE EFFECTIVENESS OF FERULIC ACID DERIVATIVES IN ALUMINIUM HYDROXIDE GEL- USP
AbstractThe selected amide and ester derivatives of ferulic acid were subjected to preservative efficacy testing in an official antacid preparation, (Aluminium Hydroxide Gel-USP) against Staphylococcus aureus, Bacillus subtilis, Escherichia coli, Candida albicans and Aspergillus niger as representative challenging microorganisms as per USP 2004 guidelines. The selected derivatives were found to be effective against all selected strains and showed preservative efficacy comparable to that of standard and even better in case B. subtilis and C. albicans. The 8- hydroxy quinoline ester derivative showed better preservative efficacy than standard as well as other derivatives and have better potential for use in the pharmaceutical preparations.
