In this paper, the author aimed to determine the nutritional value of soursop (Annona muricata L. fruit) consumed in Kinshasa as well as the study of the acute toxicity of its seeds. The fruit of Annona muricata L. was sampled according to the ISO 7002 standard for agricultural and food products. The selected fruits were ripe, without physical damage. The usual analytical methods allowed the determination of the nutritional value of the fruit pulp of Annona muricata L. The water content was measured by the method of loss of mass on drying. The total amount of ash was determined by incineration in the oven at 550°C. The mineral elements were determined by inductively coupled plasma spectrometry (ICP0). The determination of acute toxicity was carried out on 25 female mice of the NMRI SUISSE species according to OECD 425 guidelines. For 100 grams of fresh material from the fruit pulp, we noted a very high water content of 84% ± 6%. We also note a particularly high amount of carbohydrates with a rate of 12.2% ± 2%. Protein and lipid content were relatively low at 1% ± 0.01% and 0.7% ± 0.3% respectively. The dietary fiber content was 0.8% ± 0.2%. An energy value of 49.3 Kcal per 100 grams of pulp was determined. The LD 50 obtained was 3320 mg/kg, indicating slight toxicity of soursop seeds. The results of this study show that the white pulp of the fruit of Annona muricata L. consumed in Kinshasa is rich in carbohydrates when we compare it to others biomolecules. It also contains dietary fiber and mineral salts making soursop an excellent constituent of a weight loss diet with a low energy intake.
