Boiled aqueous extract from five Ivorian edible leaves (Solanum scabrum, Ipomea batatas, Corchorus olitorius, Basella alba, Hibiscus sabdariffa) have been analyzed for their antioxidant contents, phytochemical and nutritional compositions. I. batata extract showed the highest amount of antioxidant (167.52 µg/100gTE), total polyphenol (34.18 mg/100 g TE) and total flavonoid (12.67 mg/100g TE). The higher energy value (225.5 kcal) was obtained in S. scrabrum extract. The highest amount of zinc and potassium were found in S. scrabrum extract (0.28 and 362.1 mg/100 g DW; respectively). Maximum amount of copper (1.16 mg/100 g DW) and calcium (777.9 mg/100 g DW) were obtained in H. sabdariffa extract. The highest content of iron (49.81 mg/100 g DW) and magnesium (201 mg/100 g DW) were observed in B. alba extract. The highest content of sodium (2.39 mg/100 g DW) was obtained in C. olitorius extract. All extracts contained secondary metabolites such as polyphenols (tannins, flavonoids), sterols and terpenes, which have medicinal potent.

Black hair suffers from a lipid deficiency, either on the surface with a decrease in sebaceous secretion or in depth with a lack of covalent bonds between the lipids and the cuticular cells. The result is a porous cuticle, a dull, rough hair that is difficult to untangle and breaks easily. The aim of this study was to evaluate properties of oils extracted from Cocos nucifera and Elaeis guineensis intended for the formulation of shampoos for black hair. Physicochemical and rheological analyses were carried out. Both oils showed a refractive index of 1.45 and melting points of 28 °C and 30 °C for coconut oil and palm kernel oil, respectively. The relative densities, moisture contents, saponification indexes, peroxide values, unsaponifiable matter contents, para-anisidine values were relatively similar while iodine and acid values were different. Both oils are rich in lauric, oleic and linoleic acids. These oils exhibited a Newtonian behavior and a dominant elastic nature after their melting temperature in the study conditions. They could constitute active ingredients for the formulation of shampoo for black hair in view of their different characteristics.Keywords: Physico-chemical analyses, rheological parameters, Cocos nucifera oil, Elaeis guineensis oil.
