Mareya micrantha (Euphorbiaceae) is an Ivorian medicinal plant widely used in gastrointestinal disorders. So as to understand and identify metabolites possibly implicated in the activity of the plant on intestinal muscles, this study has been undertaken. From the crude ethanolic extract EE of the leaves, hexanic (EH), chloromethylene (EC), ethyl acetatic (EA) and butanolic (EB) sub-extracts were prepared as well as the hydroethanolic residual phase dried (Ar) and their effects on the isolated duodenum of rabbits were determined. If the sub-extracts EH, EA and EB, but also Ar, confirmed the myostimulant activity of the crude extract EE, this was not the case of EC which showed myorelaxant activity. This sub-extract, subjected to purification, led to the isolation of three major triterpenoids type 29norcucurbitacin (1-3) whose structures were confirmed using the combined analyses of their spectroscopic data (UV, MS, 1D NMR and 2D). All these molecules have shown myorelaxant activity, the most significant one being 2 with an IC50 value of 36.9 µM. These molecules would act by blocking both intracellular and extracellular calcium.

Aims: The main aim of this study is to describe the profile of lipids serum in an active and apparently healthy population consuming palm oil in the department of Jacqueville in the south of Côte d'Ivoire Methodology: We focused on 83 apparently healthy volunteers, which ages ranged between 18 to 50 years old. Within that population, 43 of them were palm oil consumers (67 g / day) while 40 others were considered as population control (30 g / day). We determined the BMI as well as blood pressure. Furthermore, we used conventional enzyme methods to measure the total cholesterol, HDL cholesterol, LDL cholesterol, and triglycerides. Results: Our results shown that, the mean BMI of palm oil consumers did not vary significantly compared to the control population. However, the two groups of subjects were overweight and both  group were in hypotension and the other hand the mean values of the lipid parameters did not vary significantly between the two study groups. In addition, the mean values of the lipid parameters (CT, C-LDL and TG) were normal in the two groups. With the exception of C-HDL, which value was lower than the reference one at the level of the two groups. Conclusion: This study did not show any influence of palm oil consumption on the mean BMI, blood pressure and lipid profile of the population.
