Studies
• Anti-Tuberculosis: Study assessed the in vitro antitubercular activity of essential oils of 11 mrfivinsl plants grown in Columbia. The major components were carvacrol, thymol, p-cymene, 1,8-cineole, limonene and beta-pinene. INH and rifampin were used for control treatments. Results showed the essentail oils from Achyrocline alata and Swinglea glutinosa were the most active and suggests A alata and S glutinosa and their identified components are potential candidates as phytotherapeutic antitubercular agents.
• Alkaloids / Cytotoxicity / Anti-Plasmodial: (1) Study isolated a new prenylated acridone alkaloid from the stem-bark of S glutinosa, along with three known acridone aklaloids. The isolated alkaloids were assessed for anti-plasmodial activity and for cytotoxicity using HeLa cells. (2) Study evaluated the in vitro anti-plasmodial activity of 11 acridone alkaloids isolated from S. glutinosa. Nine had varying range of activity against P. falcifarum, a smaller number against T b. rhodesiense. showedagainst Plasmodium falcifarum, T brucei rhodesiense and Leishmania donovani.
