Abstract: Diets with a high proportion of plants are nutritionally challenging. These food and generally medicinal plants certainly contribute to reducing hunger and mortality from diet-related diseases worldwide. The aim of this study is to assess the nutritional potential of Cleome gynandra, Hibiscus sabdariffa and Corchorus olitorius, three food plants widely consumed in Burkina Faso. The phytonutrient content of these three plants was assessed on a comparative basis. The parameters investigated in this study were: total ash and mineral content, total protein and carbohydrate content, total lipid content, vitamin C and provitamin A content. The results show that Cleome gynandra had the highest protein content at 160.6 ± 0.32 mg EBSA/g. Lipid levels were relatively close for all three leafy vegetables. They ranged from 3.36% to 4.35%, with the highest content obtained with Corchorus olitorius. Carbohydrate content values ranged from 0.05 to 0.15 mg/mg Glucose equivalent. The highest value was found in Hibiscus sabdariffa (0.15 Glucose equivalent mg/mg). The vitamin C contents of these three plants are relatively close, with the highest vitamin C content obtained with Corchorus olitorius (1.91±1.9 ug/mg). Provitamin A levels varied from 0.196 to 0.312 betac equivalent mg/g ES. The highest content was obtained with Cleome gynandra. Zinc, Calcium, Potassium, Iron, Magnesium and Sodium are also present in all three plants, with varying levels. Cleome gynandra stands out with higher levels of Zinc (59.79 mg/kg), Calcium (9517.5 mg/kg), Potassium (5817.5 mg/kg) and Iron (212.1 mg/kg). These different values justify cleome gylandra's highest total ash content. These edible plants are therefore rich in phytonutrients, and their consumption could help ensure good health and prevent various chronic diseases.

Abstract: This work focuses on a phytochemical study of the mucilage contained in the leaves and barks of African baobab (adansonia digitata L). The objective of this phytochemical study is to determine the presence of polyphenols in the mucilage derived from baobab leaves and bark. These phenolic compounds are vital for maintaining optimal health, as they combat the presence of fats and cardiovascular disease. To achieve this, we used several samples. The leaves or barks samples were collected from three different sites: Boof Poupouye (Fatick region), Ngohé (Diourbel region) and Tanime (Thiès region). Ethanol and acetone were used as extraction solvents. To extract total polyphenols or each type of polyphenol contained in the mucilage, appropriate extraction methods was performed. Thus, to determine the rates of total polyphenols, flavonoids, condensed tannins and water-soluble tannins contained in the mucilage extracted from barks and leaves, we used respectively the method of Folin-Ciocalteu, Marinova and collaborators, and one based on the reaction with iron trichloride and the colorimetric method. The content of polyphenols depends to many factors such as the site, the extraction solvent and plant organs (barks or leaves). Indeed, in all the sites studied, the results showed that the concentration of total polyphenols and flavonoids were relatively higher in the leaves than in the barks. A similar result was obtained for tannins within the sites of Boof Poupouye and Tanime. On the other hand, in the Ngohé site, the rates of condensed tannins and water-soluble tannins were higher in the barks. In all the cases studied, the highest rates were noted in the ethanolic extracts. The predominance of some factors (site, extraction solvent and plant organ) on variations of polyphenols and flavonoids was confirmed by statistical studies (ANOVA) while the tannins difference were more relatives to the chemical nature or operating methods.

Abstract: Palm oil is widely consumed in Côte d'Ivoire and is accused of causing hypercholesterolemia, which justifies the evaluation of the impact of its consumption on the increase in total cholesterol in Ivorian people. This was a prospective cross-sectional analytical study involving 2862 palm oil consumers over a 11-month period. The study was carried out in the health districts of Côte d'Ivoire and in the medical biochemistry laboratory from medical Teaching School. The majority of subjects in this study consumed palm oil i.e. 98.8% of the 2862 surveyed. A lipid profile was performed: total cholesterol, triglycerides, HDL cholesterol and LDL cholesterol in these subjects. Female are predominant (51.1%) and the mean age was 39.75 ± 14.31 years. Palm oil consumption was reported by 82.9% of individuals with hypercholesterolemia and 85.0% of those without hypercholesterolemia, showing no significant difference (p = 0.720) They had a mean total cholesterol level of 1.8±0.5 g/L and an atherogenicity index of 4.3±1.6. However, there was no significant correlation with the quantity of palm oil consumed. In this dataset, palm oil consumption does not appear to be a significant predictor of hypercholesterolemia in the Ivorian population. Overall, although no statistically significant association was found between palm oil consumption and hypercholesterolemia, it is essential to consider other potential factors that may affect cholesterol levels. Given its beneficial biochemical properties and various health benefits, regular consumption of this oil should still be encouraged.
