Antioxidant and larvicidal activities of Tephrosia egregia Sandw against Aedes aegypti.
The antioxidant and larvicidal activities of Tephrosia egregia extracts and its major component, dehydrorotenone, were studied. High antioxidant activity was found for dehydrorotenone and methanol and ethyl acetate extracts from roots and stems, respectively. Among the tested extracts, the hexane extract from stems showed potent larvicidal activity (LC50 12.88 +/- 0.64) while low activity was found for dehydrorotenone.
