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. Keywords: Tephrosia egregia, flavonoids, antioxidant activity, larvicidal activity, Aedes aegypti. The genus Tephrosia (Leguminoseae Papilonoideae Fabaceae) is constituted of approximately 300 species, that are distributed in tropical and subtropical regions [1a]. These species present, in their chemical composition, steroids, amino acids and flavonoids, including the rotenoids [1b]. The composition of the essential oil of leaves and stems from Tephrosia egregia has been reported [1c]. Restrictions on the use of synthetic antioxidants, are being imposed because of their potential carcinogenicity [1d]. The indiscriminate use of insecticides such as organochlorines, carbamates and pyrethroids as well the widely used larvicide Temephos, is creating problems of environmental pollution, insecticide resistance and toxic hazards to humans [1e]. Consequently, the need to identify alternative natural and safe sources of antioxidants and larvicides has arisen, and the search for natural agents has therefore increased in recent years.
The ethyl acetate extract from fresh leaves LEA; extract from fresh stems: hexane SH, dichloromethane SD and ethyl acetate SEA; methanol extract from fresh roots RM and dehydrorotenone 1 were evaluated and the results of antioxidants and larvicidal activities are recorded in Tables 1 and 2 respectively. The present results indicate that Tephrosia egregia exhibits antioxidant ability in all investigated plant extracts, especially in the fresh root methanolic extract RM (76.18% radical scavenging activity at a concentration of 1.0 mg/mL). Dehydrorotenone 1 has demonstrated very good antioxidant potential (73.79% radical scavenging activity at a concentration of 1.0 mg/mL and 56.77% at concentration of 0.25 mg/mL). These results are in agreement with the literature that describes polyphenols and flavonoids as the plant constituents with probable free radical scavenging action [1f]. A

high larvicidal activity against Aedes aegypti was observed for SH, with an LC50 12.88 μg/mL whereas dehydrorotenone 1 was less active. These results suggest that Tephrosia egregia could be a potential source of free radical scavengers, indicating possible future use as a medicinal agent and a natural larvicide in the control of Aedes aegypti. Experimental
Plant material: Leaves, stems and roots of T. egregia Sandw were collected at the flowering stage in July 2001 in Trairi-Ceará (Brazil). A voucher specimen (#EAC30839) is deposited at the Herbário Prisco Bezerra, Universidade Federal do Ceará- Brazil. Isolation of dehydrorotenone (1): The fresh roots (320 g) of T. egregia were extracted successively
with methanol. The extract obtained (6.58 g, 2.05%) was chromatographed on a silica gel column eluted with hexane, dichloromethane, ethyl acetate and methanol. The fraction dichloromethane was submitted to successive chromatographic fractiona-tion in silica gel using hexane and CH2Cl2 as eluent to yield 1 (24.8 mg) which, based 2D NMR analysis, was identified as dehydrorotenone [2a]. Free radical scavenging activity: The antioxidant activities of extracts and dehydrorotenone 1, were assayed on the basis of the radical scavenging effect of the stable DPPH free radical. One milliliter of a 60 µM DPPH ethanol solution was added to sample solutions of different concentrations and allowed to react at r.t. After 30 min the absorbance values were measured at 517 nm and the antioxidant activity was determined [2b,2c]. Each test was performed in triplicate. Data were evaluated through regression analysis. From regression line, the IC50 values were read representing percentage of scavenging free radical DPPH for 50% activity. Larvicidal bioassay: Aliquots of the essential oils tested (12.5 to 500 μg/mL) were placed in a beaker (50 mL) and dissolved in DMSO/H2O 1.5% (20 mL). 50 instar III larvae of Aedes aegypti were delivered to each beaker. After 24 hours, at room temperature, the number of dead larvae was counted and the lethal percentage calculated. A control using DMSO/H2O 1.5% was carried out in parallel. For each sample, three independent experiments were run [3]. Acknowledgments - Authors are indebted to Prof. F. S. Cavalcante for botanical identification, CENAUREMN for NMR, and to Brazilian agencies FUNCAP, CAPES and CNPq for financial support.
