Anti-obesity Effects of the Administration of Tournefortia paniculata Cham Extract on Wistar Rats Subjected to a Hypercaloric Diet

摘要

The aim of this study was to evaluate the therapeutic and toxicologic effects of the administration of the powered vegetable extract and aqueous extract of Tournefortia paniculata leaves on Wistar rats, subjected to a hypercaloric diet for 42 days. The rats were divided into five groups and were given the following treatments by gavage: T0 (control) - 1.0 mL water day-1; T1 - aqueous extract containing 14 mg phenolic compounds kg-1 rat day-1; T2 - 14 mg quercetin kg-1 rat day-1; T3 - 50 mg powered vegetable extract from T. paniculata leaves (PVE) kg-1 rat day-1 and T4 - 100 mg PVE kg-1 rat day-1. The treatments did not significantly alter the weight, but were effective in reducing liver fat, glucose and serum triglycerides. The treatment T1 reduced food consumption and lipid peroxidation. None of the treatments showed genotoxic potential. Results showed that T. paniculata leaves possessed an anti-obesity potential. However, a more detailed study of the medicinal potential and characterization of phytochemicals in this plant would be still necessary for a better understanding of its mechanisms of action, enabling future applications in the treatment of this pathology or for various therapeutic purposes.
