Caracterização química e avaliação biológica do extrato e frações de Mimosa caesalpiniifolia BENTH. (MIMOSOIDEAE)

Abstract

Mimosa caesalpiniifolia Benth., native plant and high occurrence in semi-arid areas of Brazil. It is used by local populations as forage and is used in folk medicine as a healing, anti-inflammatory and upper respiratory tract. His family and gender have experimentally proven pharmacological activities such as anticancer activity, anti-inflammatory and antimicrobial, due to the presence of secondary metabolites such as tannins, phenolic acids and flavonoids. However, most of the chemical and biological activities of M. caesalpiniifolia remain unknown. The obtained extract was due to the percolation process, using 70% hydroalcoholic liquid extractor. In step Pharmacobotany, tests were conducted seeking the botanical knowledge of the species under study. Pharmacognostic In step, the extract and the fractions were identified by comparison with authentic standards and the usual spectroscopic techniques (HPLC-PDA and HPLC-MS). Antimicrobial activity used in the broth microdilution method, the extract and the fractions showed growth inhibitory activity against microorganisms and evaluated at concentrations 5-1000 µg/mL. In anticancer activity results showed significant antiproliferative activity. The morphological analysis of the Fr-EtOAc was considered the most active fraction. In the assay of granuloma, a reduction in granuloma tissue formation in the animals treated with Fr-EtOAc and Fr-BuOH at a dose of 100 mg / kg, followed by Fr-AqOH EHM and 300 mg / kg. In the model was observed antinociceptive three doses 30, 100 and 300 mg / kg EHM, were able to produce significant reduction in mechanical hypernociception induced by injection of carrageenin. In the open field test and toxicity samples did not influence the general activity and death of animals. These results indicate that the extract and fractions of M. caesalpiniifolia tested, may constitute a potential target in developing new drugs for the pharmacological control of inflammatory processes, and microbiological and anticancer knowledge of chemistry
