ABSTRACT

The aim of this study was the valuation of the underexploited said plants still called " spontaneous plants " through the realization of the ethnobotanic study and the determination of physical Charasteristics and antinutritional factors of fruits of M.aboreus. Results showed that Fruits of Myrianthus arboreus were known of the population of Côte d’Ivoire. The vernacular names were different from an ethnic group in an other one. The mode of obtaining of fruits were stay the picking and the collection. Fruits of Myrianthus arboreus were consumed under the fresh forms. On the other hand seeds remain unexploited. The seeds of Myrianthus arboreus had 1,23 cm long and 0,97 cm wide. As for fruits, they had a length of 13,56 cm and a width of 10,29 cm. The masses of fruits and seeds of Myrianthus arboreus were respectively of 360,15 g and 0,30 g. These high masses of fruits of Myrianthus arboreus could give some explanation by their strong moisture contents. Indeed, the moisture content (85,5 %) fruits was widely superior to the rate authorized for a good conservation of fruits (12 %). The analysis of the antinutritional factors results showed that the studied samples had of very low content in these parameters. Indeed, the rate of Phytate varied to 15,49 ± 0,83 to 20,25 ± 0,39 mg/100g of the MS with the strongest value observed in the boiled seeds. The oxalates contents were between 54,38 ± 12,55 to 270,4 ± 0,01mg/100g of MS, whose low rate most was recorded in the pulp of the fruit. The polyphénoloxydasique activity of the enzymatic raw extract of seeds is significantly superior to that of the raw extract of the pulp at the threshold of 5 %.
