Abstract


A study on the nutritional and toxicological analyses of three wild plants, fruits of: Capsicum frutescens, Passiflora foetida and the leaves of Piper umbellatum were analyzed. In this study, it appears that these wild plants may be of value as a food supplement in regard to their content in crude proteins, lipids, calcium, magnesium, iron, phosphorus, and vitamins (A, B1, B2, B6 and C). The fruits of Capsicum frutesceus are richer in crude ash (14.42%), protein (3.18%), vitamin B2 (1.46 g / 100 g), and iron (4,108 g/100 g). The fruits of Passiflora foetida are richer in water (75.49%); citric acid equivalent (17.732%), lipid (14g / 100g), vitamin B1 (4,98 g /100 g), vitamin C (17.6 g/100 g), calcium (2.28 g/100 g) and leaves of Piper umbellatum are richer in vitamin A (0.933 g/100 g), magnesium (1.787 g/100 g), phosphorus (0.016 g/100 g). However, these plants also contain some undesirable substances including alkaloids and terpenes and sterols, trace toxic substance such as nitrate, nitrite and cyanide. All these results justify the use of these plants in the diet of the population of the city of Kisangani and its surroundings for the diversification of the diet to fight against the lack of certain nutrients.

Author Keywords: Nutrition, wild plants, traditional foods, chemical analysis, anti-nutritional factors.


Abstract: (french)


Une étude sur l’analyse nutritionnelle et toxicologique de trois plantes alimentaires sauvages, fruits de : Capsicum frutescens, Passiflora foetida et feuilles de Piper umbellatum ont été analysés. De cette étude, il ressort que ces plantes alimentaires sauvages peuvent constituer un complément alimentaire de valeur en ce qui concerne les protéines brutes, les lipides, le calcium, le magnésium, le fer, le phosphore et les vitamines (A, B1, B2, B6 et C). Les fruits de Capsicum frutescens sont plus riches en cendres brutes (14,42%), protéines (3,18%), vitamine B2 (1,46g/100g), fer (4,108 g/100 g). Les fruits de Passiflora foetida sont plus riches en eau (75,49%), équivalent acide citrique (17,732%), lipide (14 g/100 g), vitamine B1 (4,98g/100g), vitamine C (17,6g/100g), calcium (2,28g/100g) et les feuilles de Piper umbellatum sont plus riches en vitamine A (0,933g/100g), magnésium (1,787g/100g), phosphore (0,016g/100g). Cependant ces plantes contiennent également quelques substances indésirables notamment les alcaloïdes, stérol et terpènes, des traces de substance toxiques tels que les nitrates, nitrites et cyanures. L’ensemble de ces résultats justifie l’utilisation de ces plantes dans l’alimentation de la population de la province de la Tshopo pour la diversification du régime alimentaire afin de lutter contre la carence de certains nutriments.

Author Keywords: Nutrition, plantes sauvages, aliments traditionnels, analyse chimique, facteurs antinutritionnels.
