Abstract
Blighia sapida is a plant with many therapeutic virtues. In Ivory Coast, this plant is widespread in several regions with different climatic conditions. The aim of our study is to compare the effects of aqueous extracts of Blighia sapida harvested in three Ivorian regions on the biochemical parameters of rats made hypertensive by a fructose diet. Rats (20) were fed a high fructose diet (70% fructose, 10% fat, 20% protein) for 30 days. Then blood pressure was measured from an armband to the tail of the rats. Finally, biochemical and lipid parameters were measured before and after the fructose-enriched diet. All rats fed the high-fructose diet had similar rates of hypertension (SBP = 160.0 ± 0.07 mmHg; DBP = 141.5 ± 1.21 mmHg; HR = 325.7 ± 1.52 beats/min) and a change in dosing parameters. Aqueous extracts of Blighia sapida from Adzopé (EAA) and Korhogo (EAK) administered to hypertensive rats normalized the previously increased cardiovascular, biochemical, and lipid parameters compared to control rats (healthy and untreated diseased rats). However, the aqueous extract of Blighia sapida of Adzopé (EAA) showed the best effects on hypertension compared to the aqueous extract of Blighia sapida of Korhogo (EAK). Indeed, the more humid the region and the climate, the more effective the extract is. The regulating effect of aqueous extracts of Blighia sapida on blood pressure, therefore, differs from one region to another with different climatic conditions. This would explain its use in traditional medicine in certain climatic zones compared to others where its therapeutic effects would be unknown because less. Adzopé would, therefore, be the best region where Blighia sapida should be harvested for the optimal treatment of high blood pressure.
