Solanum torvum is a spontaneous food plant consumed in several regions in Côte d’Ivoire. The cooked berries of this plant are reportedly used in some rural areas to stimulate appetite in convalescing people. The objective of this study was to characterise the biochemical composition and to evaluate the appetite-stimulating potential of cooked S. torvum berries in anorexic rats. So, the berries were cooked in water for 30 minutes at 100 °C and analyzed for pH, titrable acidity, proteins, lipids, total carbohydrate, phenolic compounds, and β-Carotene determination. These berries were also administrated to anorexic 32 Wistar rats for 4 weeks. Appetite was assessed using parameters such as food consumed, water consumed, and body mass. The results show that S. torvum berries had a pH value that tends towards neutrality (6.84 ±0.01). Proteins, lipids, and carbohydrates values were respectively 10.018 %, 9.55% and 50.296 %. β-carotene was 88.37 µg/100 g FM. Polyphenols and flavonoids indicated values of 428.356 mg EAG/g and 3.236 mg EQ/g, respectively. The aqueous extracts of S. torvum berries at the concentration of 6.4 mg/mL increase water and food consumption. It also allows a greater gain in rats’ body mass. A high concentration of S. torvum berries could improve appetite.
