Abstract
Campomanesia xanthocarpa popularly known as gabiroba is used as a medicinal plant for the treatment of inflammatory diseases, ulcers, among other uses, requiring studies to assist in proving these activities. In this study, the extract of leaves from C. xanthocarpa (CxHE) was submitted to assays of formalin-induced paw-licking, peritonitis induced by lipopolysaccharide and carrageenan-induced mechanical hyperalgesia tests. In chemical analysis, a preliminary phytochemical screening and the determination of phenol and flavonoid content were carried out, in addition to analysis by ESI-MS/MS system and HPLC-DAD system. The CxHE presented compounds such as tannins, triterpenoids, steroids and saponins and content of phenols (35.9 ± 1.3 GAE/g extract) and flavonoids (23.3 ± 2.1 mg EQ/g extract). Protocatechuic acid, gallic acid, ethyl gallate, quercetin, and 3-methyl epigallocatechin gallate, alpha and beta-amyrins were identified. CxHE at doses of 10-1000 mg/kg p.o. demonstrated anti-inflammatory and antinociceptive effects in all in vivo assays employed in this study.
