Phytochemical analysis of the two plants showed the presence of alkaloids, saponins, tannins, flavonoids and anthraquinones in petroleum ether, ethyl acetate, methanol and water extracts. The effectiveness of the two medicinal plants viz: P. africana and A. occidentale was tested against the causative agent of root rot of Sesamum indicum L. The effect of plant leaf extracts on mycelia growth of the test organism shows that both P. africana and A. anacardium reduced the mycelia growth significantly as compared to the control (plate, 2, 3, 4). The antifungal property of P. africana and A. occidentale makes these plants of potential interest for the control of the fungi Macrophomina phaseolina.展开更多
