Valorization of Vitex doniana fruits requires the development of appropriate technologies. In order to guide these technologies, a survey to determine the profile of consumers was conducted in the department of Bondoukou, followed by a physical and chemical characterization of the fruits of this area. For this, classical methods of analysis have been used. The results indicate that black plum are available, accessible during a given period of the year and are not preserved. The seed is not subject to any transformation. At the physical level, the fruit measures on average 2.46 ± 0.35 cm wide and 2.80 ± 0.31 cm long with a caliber index, a sphericity index and an aspect ratio of 3.42 ± 0.60, 62 ± 7.0% and 89.84 ± 14.22% respectively. The pulp and seed represents 57, 38-± 10.66% and 31.57 ± 9.64% of the whole fruit respectively. Color of the pulp is dark reddish purple with L * = 3.59 ± 0.82, a * = 21.91 ± 3.14, b * = -21.36 ± 2.9, C * = 475.34 ± 102.55 and h * = 38.92 ± 8.99, and its density ρ (g /cm3) is 121.33 ± 55.44. Chemically, its pH, moisture content, soluble dry extract content and degree of ripeness are 4.79 ± 0.03, respectively, 69.18 ± 1.02%, 18.53 ± 1.36 ° B and 10.80 ± 1.51. These characteristics are quite important for the implementation of applicable technologies. These characteristics of plum of savannas are quite important for the implementation applicable technologies.
