ABSTRACT
This study demonstrates in vivo analgesic and anti-inflammatory properties of hydroalcoholic extracts of leaves, bark and flowers from the Handroanthus impetiginosus (Bignoniaceae) plant, recognized as 'Ipê roxo' in Brazil. The extracts were evaluated in male Swiss albino mice via oral administration. Moreover, results of the in vivo paw oedema test induced by carrageenan revealed that extracts of leaves and bark displayed relevant anti-inflammatory activity potential at the dosage of 100 mg/kg, 300 mg/kg, and 500 mg/kg. Likewise, the results obtained for leaves and flowers extracts suggested potent analgesic action in the conventional hot plate test. UPLC/MS analysis of the hydroalcoholic extracts samples identified metabolites belonging to several classes, mainly naphthoquinones and iridoids derivatives as well as flavonoids. Thus, the obtained results indicate that the extracts of H. impetiginosus plant parts could be considered as a complementary herbal medicine for the treatment of pain and inflammation disorders.
