Summary

Descripción general del contenido del recurso.

A atividade antiinflamatória de extratos éter petróleo, diclorometânico e metanólico de <i>Heterotheca subaxillaris</i> var. <i>latifolia</i>, foi testada pelo método de edema induzido pelo 12-<i>O</i>-tetradecanoil phorbol acetato (TPA) na orelha do camundongos e pelo método do edema de pata induzido por carragenina em ratos. O extrato diclorometânico mostrou atividade antiinflamatória significativa (91% inibição) no edema de orelha induzido por TPA (administração tópica de 1 mg/orelha). Não houve efeitos significativos no teste do edema induzido pela carragenina. O fracionamento bioguiado das frações ativas levou ao isolamento dos flavonoides majoritários santina, pectolinaringenina, 3,6-dimetoxi-5, 7,4 ‘-trihidroxiflavona e hispidulina. The anti-inflammatory activity of the petroleum ether, dichloromethane and methanol extracts from <i>Heterotheca subaxillaris</i> var. <i>latifolia</i> were assayed using 12-<i>O</i>-tetradecanoyl phorbol acetate (TPA) induced ear edema test in mice and carrageenan-induced paw edema test in rats. The dichloromethane extract showed a significant anti-inflammatory activity (91% of inhibition) in TPA-induced ear edema test (topical administration at 1 mg/ear). No effects were seen on carragenan-induced edema. Bio-guided fractionation deal to the isolation of the major flavonoids santin, pectolinaringenin, 3,6-dimethoxy-5,7,4'-trihydroxyflavone and hispidulin present in the active fractions.
