RESUMEN
Campomanesia xanthocarpa, a plant belonging to the Myrtaceae family, is popularly known as gabiroba. Leaves of gabiroba has been popularly used to treat various diseases, including inflammatory, renal, and digestive, among others. Additionally, studies have shown an effect to reduce blood cholesterol levels. The aim of this study was to evaluate the antihyperglycemic and hypolipidemic effects of Campomanesia xanthocarpa seed extract in hyperglycemic rats. The results showed that 400 mg/kg of seed extract was able to decrease blood glucose levels and to increase the muscular and hepatic glycogen content as well as to inhibit the sucrase and maltase activity. At doses of 200 mg/kg and 800 mg/kg, the activity of these enzymes was also reduced. In the lipid profile 400 mg/kg produced a decrease in total and LDL cholesterol serum levels; and with 200 mg/kg there was an increase in HDL cholesterol levels. The extract did not present hepatic and renal toxic effects at the different doses tested. The results suggest that the treatment with Campomanesia xanthocarpa seeds extract is useful in reducing glycemia, total cholesterol and LDL levels with potential adjuvant therapeutic in the treatment of diabetes and hypercholesterolemia, however, additional pharmacological and toxicological studies are still required.(AU)
Campomanesia xanthocarpa, planta pertencente à família Mirtaceae, é popularmente conhecida como gabiroba. Folhas da gabiroba são popularmente usadas para tratar de doenças inflamatórias, renais, digestivas entre outras. Além disso, estudos têm mostrado um efeito redutor dos níveis de colesterol. O objetivo deste estudo foi avaliar os efeitos anti-hiperglicêmico e hipolipidêmico do extrato de sementes de Campomanesia xanthocarpa em ratos hiperglicêmicos. Os resultados mostraram que 400 mg/kg do extrato da semente foi capaz de reduzir os níveis de glicose sanguínea e aumentar o conteúdo de glicogênio hepático e muscular, bem como inibir a atividade da maltase e sacarase. Na dose de 200 mg/kg e 800 mg/kg, a atividade das enzimas também foi reduzida. No perfil lipídico, 400 mg/kg produziu uma redução nos níveis séricos de colesterol total e LDL e com 200 mg/kg houve um aumento nos níveis de colesterol HDL. O extrato não apresentou efeitos tóxicos hepáticos e renais nas doses testadas. Os resultados sugerem que o tratamento com o extrato de Campomanesia xanthocarpa é eficaz na redução da glicemia, de colesterol total e LDL com potencial para tratamento adjuvante do diabetes e hipercolesterolemia, no entanto estudos farmacológicos e toxicológicos adicionais são necessários.(AU)
