Extracts were prepared in different water and alcohol compositions at different time intervals. These prepared extracts were chromatographed and number of phytoconstituents was present. Some of the extracts were used for performing anti-inflammatory activity. The activity was performed by carrageneaninduced paw oedema method in rats. A few extracts were found effective reducing the oedema.
