Another Indian species, C. inerme also inhibited the growth of larvae of Ades aegypti, Culex quinquefasciatus and Culex pipiens at 80 and 100 ppm concentration of petroleum ether and ether extracts (Gayar and Shazll 1968; Kalyanasundaram and Das 1985). C. myricoides a species from Southern Africa was also tested positive for its antimalarial activity against both sensitive and resistant strains of P. falciparum with IC50< 30 µg/ml (Muregi et al. 2004), it also showed 31.7% suppression in parasitaemia against cloroquine tolerant strain of Plasmodium berghei NK65 (Muregi et al. 2007). These plants may be useful as a source for novel anti-plasmodial drugs/compounds from natural origin.
