Abstract

Callus cultures from stem of Ocimum sanctum were induced on slightly modified Murashige and Skoog's medium and supplemented with 2,4-dichlorophenoxyacetic acid (2ppm) and kinetin (1ppm). Different extracts of stem, leaf and stem calli of O. sanctum were tested for antiinflammatory activity using carrageenan-induced rat paw oedema model in comparison with the standard indomethacin. The ethanol extract of callus tissue exhibited maximum significant antiinflammatory activity out of all extracts studied followed by ethanol extracts of leaves of O. sanctum.
