Antiobesity Effects of Hydroethanolic Extract of Jacaranda decurrens Leaves

الملخص EN

Obesity is a worldwide epidemic that reduces life expectancy; therefore, the search for new alternative and effective treatments is ongoing.

The aim of the present investigation was to identify the chemical compounds in the hydroethanolic extract of leaves of Jacaranda decurrens subsp.

symmetrifoliolata and to evaluate their toxicity and antiobesity effects.

High-performance liquid chromatography was used to identify the chemical constituents, and acute toxicity was evaluated in rats treated with doses of 2 and 5 g·kg−1 body mass.

The antiobesity effect was determined in rats with hypercaloric diet-induced obesity.

Our results revealed the presence of compounds, such as jacaric, ursolic, and oleic acids, as well as luteolin, quercetin, and kaempferol, in the extract.

The acute toxicity tests revealed that rats treated with elevated doses of the extract showed no signs of toxicity.

The extract induced reduction in total body mass and the white adipose tissue depots.

The obese rats treated with the extract showed an increased fluid intake and feces excretion while their serum total cholesterol and triglyceride levels decreased compared to those in the controls, without any hematological changes.

Taken together, the results showed that the constituents of J.

decurrens extracts included phenolic compounds and exhibited antiobesity effects with no toxicity.
