Ethnobotanical survey, mineral and phytochemical composition of Byttneria catalpifolia and Sida urens: Two spontaneous plants consumed in households in the city of Man

This study aims to promote the wild food plants consumed in households in the city of Man. To achieve this objective, an ethnobotanical survey was conducted in 90 households distributed in three districts of the city of Man, in order to inventory the wild plants that are consumed there. The survey was completed by the mineral and phytochemical analysis of two plants selected following the survey carried out in the city. The results obtained make it possible to identify 34 plant species, 27 of which have been identified, divided into 21 botanical families. The majority of the plants mentioned are consumed for their taste (87%) and as a sauce (90%). The mineral and phytochemical analysis of the plants studied Byttneria catalpifolia and Sida urens showed High levels of polyphenol (23.37± 0.82 mg EAG/gp), calcium (80.9%) in the plant Byttneria catalpifolia while the potassium (11.4%) was moderate and that copper, chlorine of flavonoid (1.77 ± 0.28 mg EQ/gp) was low. The results also revealed the presence of compounds such as terpenes, saponins, coumarins, proteins in the plant Byttneria catalpifolia The plant Sida urens showed a low content of copper (0.05%), chlorine (0.2%) and flavonoid (1.17± 0.03 mg EQ/gp) On the other hand, the moisture content (10%), ash (18%), calcium (62%), iron (14.9%), potassium (14.7%), polyphenol (29.16± 0.042 mg EAG /gp) were high. Let us remember from this study that the city of Man contains a variety of wild food plants and most of these plants contain appreciable amounts of nutrients.
