Validated High Performance Thin Layer Chromatography Method for Simultaneous Estimation of Ofloxacin and Ornidazole in Tablet Dosage Form

.co m) . was displayed by Terminalia chebula seed extract against B. cereus. In fact, this plant extract (both aqueous and ethanolic) could inhibit all the bacterial strains investigated. Out of 50 aqueous extracts, 16 extracts showed activity against any one of grampositive bacteria, while only 10 extracts showed activity against any one of gram-negative bacteria. The plant extracts inhibited the gram-positive microorganisms better than gram negative microorganisms. This is in agreement with previous reports that plant extracts are more active against gram-positive bacteria than gramnegative bacteria. From our investigation for screening of different plant species, the results obtained confirm the therapeutic potency of some plants used in traditional medicine. In addition, these results form a good basis for selection of plant species candidates for further phytochemical and pharmacological investigation.
