This study aims to determine the mineral composition of green teas and herbal tea in the savannah tea plant. Samples of buds, young leaves and broadleaf stems were collected from wild plants of Lippia multiflora in three localities, including two from the Center (Yamoussoukro, Toumodi) and one from the northeast (Bondoukou) of Côte d'Ivoire. The lipid and ash contents were carried out by the AOAC method. The total protein and sugar contents were determined by the Kjeldahl and Agbo methods, respectively. Nine minerals (potassium, calcium, magnesium, iron, sodium, manganese, zinc, copper and cadmium) were quantitated by Atomic Absorption Spectrophotometry (AAS) from green teas (buds and young leaves) and herbal tea of Lippia multiflora.The results showed that ash levels (7.05% -13.94%) and protein (6.22% -9.97%) were high, however the lipid contents (1.01% -2.98%) and total sugars (1.43% -4.51%) are low. Majority of the minerals are calcium (2320.91 to 36150.10 mg/kg), potassium (2110.71 to 12174.67 mg/kg) and magnesium (3620.87 -5870.46 mg/kg). Iron (52.55 to 483.11 mg/kg), sodium (35.66 to 469.16 mg/kg) and manganese (15.25 to 76.86 mg/kg) are represented in average proportions. There are small amounts of zinc (9.61 -47.50 mg/kg), copper (5.66 -8.71 mg/kg), and cadmium (0.17 -1.49 mg/kg). Lippia multiflora herbal teas and green teas are low in fat, high in ash and are good sources of protein and minerals.
The objective of this work is to analyze the biochemical parameters of Zingiber officinale (ginger) and Curcuma Longa (turmeric) found in the locality of Daloa. The samples were purchased in the markets of Daloa. The dry matter, ash and lipid contents were determined by the AOAC (Association of Official Analytical Chemists) method. Those of proteins, total sugars, reducing sugars were carried out respectively by the methods of Kjeldahl, Bernfeld and Dubois. A phytochemical study was done by Evans method. The contents of total flavonoids and total polyphenols were determined respectively according to the methods of Wood and Marinova. It emerges from the analyzes that the contents of dry matter (27.66 ± 0.06%), total sugars (31.25 ± 0.6 mg / g) and fibers (8.21 ± 0.01%) are higher in ginger than in turmeric. The lipid contents of the two species are less than 8%. The results also reveal the presence of tannins, saponins, polyphenols, alkaloids and flavonoids. Ginger has a high content of total polyphenols (53.55 ± 0.45 mg EAG / g) than turmeric (35.25 ± 0.52 mg EAG / g). However, the flavonoid values are high in turmeric (92.52 ± 0.54 µg EQ / g) than ginger (86.27 ± 0.62 µg EQ / g). Both turmeric have revealed that ginger and turmeric are low in fat, reducing sugars, and high in fiber and polyphenols. Both rhizomes have the same protein content. The presence of secondary metabolites in the rhizomes of ginger and turmeric justifies the therapeutic importance of these two plants, hence the importance of consuming them to take full advantage of the beneficial effects of its active ingredients. However, the compounds vary from species to species.
Objectif : Ce travail vise à connaitre les différentes utilisations d’Alchornea cordifolia dans la localité de Daloa (Côte d’Ivoire). Méthodologie et résultats : Il a été mené sous forme d’enquête, auprès des tradipraticiens, des vendeuses et des consommateurs d’Alchornea cordifolia dans la ville de Daloa. Les résultats indiquent que les feuilles sont utilisées à 60,7 % par les enquêtés. Le type de changement observé au cours des différents temps de préparation est préférentiellement la couleur (60,71 %), suivi de la saveur (29,28 %) et enfin de l’arôme 10 %. Les feuilles séchées sont les plus consommées (87,71 %) contre 14,28 % des feuilles fraîches. Le nom vernaculaire est fonction du groupe ethnique. Alchornea cordifolia est une plante qui est utilisée plus pour ses vertus médicinales (83,70 %) que nutritionnelles (16,30 %). Les enquêtés (84,29 %) souhaitent la transformation des feuilles d’Alchornea cordifolia sous forme de thé. Conclusions et application des résultats. Il ressort de cette enquête que, Alchornea cordifolia est une plante qui possède des vertus nutritionnelles et médicinales. Les organes de cette plante sont utilisés en pharmacopée traditionnelle. Les feuilles sont les parties les plus utilisées chez cette plante. Les feuilles sont les organes permanents sur les plantes et donc disponibles sur toute l’année. La transformation des feuilles de cette plante en thé ou en tisane pourrait contribuer à l’amélioration de l’état nutritionnel des populations de la Côte d'Ivoire.

Vol.160 :2021 Différents usages d’Alchornea cordifolia (euphorbiaceae) dans la localité de Daloa (Côte d’Ivoire) ABSTRACT Objective: This work aims to learn about the different uses of Alchornea cordifolia in the locality of Daloa (Côte d'Ivoire). Methodology and results: It was carried out in the form of a survey among traditional healers, sellers and consumers of Alchornea cordifolia in the town of Daloa. The results obtained that the leaves are used at 60.7% by the respondents. The type of study change during the different preparation times is preferably the color (60.71%), followed by the flavor (29.28%) and finally the 10% aroma. Dried leaves are the most consumed (87.71%) against 14.28% of fresh leaves. The vernacular name is a function of the ethnic group. Alchornea cordifolia is a plant that is used more for its medicinal (83.70%) than nutritional (16.30%) virtues. Respondents (84.29%) want Alchornea cordifolia leaves to be transformed into tea. Conclusions and application of the results. It emerges from this investigation that, Alchornea cordifolia is a plant which has nutritional and medicinal virtues. The organs of this plant are used in traditional pharmacopoeia. The leaves are the most used parts of this plant. Leaves are the permanent organs on plants and therefore available throughout the year.
