The fruits of Solanum torvum (Swartz), a vegetable-fruit, are used in traditional medicine in Togo in the treatment of infectious diseases and as an anti-anemic. This study then focused on the antimicrobial activity assessment of the hydroethanolic extract of these fruits in the interest of contributing to the valorization of this Togolese flora’s species. A hydroethanolic extraction (50 % - 50 %: v/v) was performed followed by preliminary phytochemical tests. Antimicrobial activity was determined on fourteen bacterial strains using the agar diffusion method. Qualitative phytochemical screening revealed the presence of alkaloids, reducing compounds, tannins, cardiac glycosides, flavonoids, coumarins, triterpenes, saponins, total carbohydrates and free quinones. The extract was active on the reference strains of S. aureus, E. coli, S. pneumoniae and P. aeruginosa. However, this activity was only observed on clinical strains of S. pneumoniae and P. aeruginosa. The extract showed MICs of 25 and 50 mg/ml and BMCs of 50 and 100 mg/ml respectively for S. pneumoniae and P. aeruginosa. The MBC/MIC ratio for these two strains was 2. These fruits would then have bacteriostatic activity on S. pneumoniae and P. aeruginosa. The antibacterial properties of the extract on these germs could justify the use of this plant in traditional medicine for the treatment of certain bacterial infections.

“…It is also cultivated as a small-scale vegetable in southern and eastern Asia, and is especially popular in Thailand [4]. In terms of traditional medicine, the berries of S. torvum have been widely investigated in many countries [2,6,7,8,9,10,11]. Extracts from these berries have generally been shown to be antioxidants, antimicrobials, anti-inflammatories, cardioprotectors, nephroprotectors, hepatoprotectors and cough suppressants.…”

Berries of solanum torvum, referred to as wild eggplant, are widely consumed in eastern Côte d'Ivoire in boiled form in sauces or soups. This study aimed to evaluate the antioxidant potential of these fruits through the estimation of antioxidant capacities of the extracts, identification and quantification of phenolic compounds and organic acids of raw berries and boiled berries to gauge the influence of this cooking. Results showed that boiling caused a considerable decrease in the antioxidant capacity of S. torvum berry extracts. By DPPH scavenging, the effective concentration (EC50) value of extract increased from 20.00 to 42.20 µg/mL, respectively for raw and boiled berries. Regarding EC50 values for antioxidant activities via FRAP, the values of 75.10 and 87.20 µg/mL were obtained, respectively for raw and boiled berries extract. In terms of phenolic compounds, the most predominant were catechin and gallic acid with respective contents of 1.06 and 0.86 mg/kg in the raw berries; 0.86 and 0.71 mg/kg in boiled berries, demonstrating the decrease in levels of these compounds by boiling. Organic acids showed the same decreasing trend during boiling. However, using cooking water when preparing soups or sauces could minimize these losses. In addition to this, one could consider other cooking methods such as steaming to better ensure nutrient retention
