ABSTRACT
Adenanthera pavonina L, Fabaceae alt. Leguminosae, Bengali name 'rakta kombol', is an Indian medicinal plant. It is endemic to Southern China and India, and widely naturalized in Malaysia, Western and Eastern Africa as well as in most islands of both the Pacific and Caribbean regions. This plant has been used in traditional medicine for the treatment of asthma, boil, diarrhoea, gout, inflammations, rheumatism, tumour and ulcers, and as a tonic. The dried and ground bark of A. pavonina L. was extracted, successively, with petroleum ether (PE), dichloromethane (DCM), ethyl acetate (EtOAc) and methanol (MeOH), and the resulting extracts were assessed in vivo for anti-inflammatory activity on carrageenan-induced rat hind paw oedema as a model of inflammation. The extracts were administered orally at the doses of 200 and 400 mg/kg body weight, and statistically significant (p<0.001) anti-inflammatory effects were observed in a dose dependant manner. The MeOH extract (400 mg/kg) showed 37.10 percent (p<0.01) inhibition of inflammation at the first hour of the study and, the DCM extract (400 mg/kg) exhibited 33.11 percent (p<0.001) inhibition of inflammation at the third hour of the study which was comparable with that of reference standard drug dichlofenac sodium. The results of this study supported some of the traditional medicinal uses of this plant.
RESUMO
Adenanthera pavonina L, Fabaceae, conhecida na região de Bengala por "rakta kombol", é uma planta medicinal endêmica do sul da China e da Índia e amplamente difundida na Malásia, África Ocidental e Oriental, bem como na maioria das ilhas de ambas as regiões do Pacífico e Caribe. Esta planta tem sido utilizada na medicina tradicional para o tratamento da asma, febre, diarréia, gota, inflamações, reumatismo tumor, úlceras, e como tônico. Cascas secas e moídas de A. pavonina foi submetida a extração sucessiva com éter de petróleo (PE), diclorometano (DCM), acetato de etila (AcOEt) e metanol (MeOH), e os extratos foram avaliados in vivo para atividade anti-inflamatória induzida por carragenina tendo como ensaio modelo de inflamação edema de pata em ratos.. Os extratos foram administrados por via oral em doses de 200 e 400 mg/kg de peso corporal, e foram observadas efeitos anti-inflamatórios de maneira dose-dependente, estatisticamente significativos (p<0,001). O extrato metanólico (400 mg/kg) apresentou 37,10 por cento (p<0,01) de inibição da inflamação na primeira hora do estudo e, o extrato DCM (400 mg/kg) apresentou 33,11 por cento (p<0,001) na inibição da inflamação na terceira hora do estudo, que foi comparável ao resultado da substância de referência diclofenato de sódio. Os resultados deste estudo confirmaram alguns dos usos tradicionais desta planta medicinal.
