ABSTRACT: Cassava (Manihot esculenta) is a perennial shrub in the Euphorbiaceae family. Thus, the objectives assigned to this study are to evaluate the hydrogen cyanide content of the 58 accessions of cassava in the collection to Samba and specifically, to evaluate the content of hydrocyanic acid in fresh and dried cassava leaves. To determine the pH value in each accession and to assess the phytosanitary status of the accessions. Titrimetry was used to determine hydrocyanic acid. It is used as part of this work to determine the level of hydrocyanic acid contained in cassava leaves. The results made it possible to classify the accessions analysed into three groups: accessions with a low cyanide content whose concentrations vary from 13 mg to 49.33, accessions with a moderate concentration (50.33 mg to 98.33 mg) and highly concentrated accessions (100.66 mg to 144 mg). The pH value for the different is almost identical.
