Author(s): Isabela M. Reck, Angela Kwiatkowski, Julianna M. Vagula, Edmar Clemente

Brazil stands out as a major fruit producer. However, many fruits are not yet produced in large scale due to the lack of knowledge of their cultivation practices. Solanum nigrum L. is a plant that produces small fruits known as Black-Mary. In this work, we evaluated the following characteristics: titratable acidity (TA), soluble solids (SS), TA / SS ratio, pH, vitamin C, crude protein, lipids, ashes (minerals), mineral quantification, reducing and total sugars and staining characterization (parameters a, b, C, G, H), phenolic compounds content evaluation, anthocyanins and their antioxidant activity. The results were satisfactory, especially regarding its antioxidant activity and phenolic compounds, which presented the values of 40.09% and 1036.32 mg per 100 g of sample, respectively. We can also highlight its 0.06% lipids content, 81.05% moisture and 2.25% protein content, along with significant amounts of macronutrients and micronutrients.
