The antimycobacterial activity of parts of Pterocarpus erinaceus Poir. ( Leguminosae ) was studied using the agar proportion method. Phytochemical screening was also carried out to determine the major phytochemical groups responsible for the activity. Only the stem bark of the plant was found to possess varying degrees of activity against four Mycobacterial species namely M. smegmatis ATCC 607, M. tuberculosis, M. bovis and M. avium-complex . Phytochemical screening of the active fractions revealed the presence of flavanols and terpenes/sterols in the fraction isolated from the hexane crude and tannins and terpenes/sterols in the fraction isolated from the methanol crude. The minimum inhibitory concentrations of the active fractions ranged between 0.25 mg/ml and 2.0 mg/ml. Keywords : flavanols, terpenes/sterols, antimycobacterial activities, Pterocarpus erinaceus East and Central African Journal of Pharmaceutical Sciences Vol. 7 2004: 40-45 |
