Estudio fitoquímico preliminar y evaluación de la actividad antioxidante de Solanum Pimpinellifolium

Abstract

Abstract: Solanum pimpinellifolium L., known as "currant tomato" is a wild species of tomato. The objectives of this research were to carry out a preliminary phytochemical study of this species. Polar extracts were obtained in ethanol (EtOH), ethanol-water (EtOH-H2O) and water (H2O), and the antioxidant capacity and the amount of total phenols were evaluated. The extracts were obtained from the mature fruits of the plant, after being lyophilized, by a static maceration process, using ethanol and water as solvents. The Folin-Ciocalteu method was used to evaluate the total phenol content, and the ABTS and DPPH methods were used to evaluate the antioxidant capacity, the extracts were subjected to a preliminary phytochemical study using presence-absence methods for proteins, carbohydrates, fats, alkaloids, terpenes-steroids, flavonoids, saponins, quinones and tannins; the EtOH-H2O extract had a higher content of phenolic compounds 3. 53 ± 0.13 mg/Eq gallic acid/ 100 g of dried fruit, EtOH extract presented 2.48 ± 0.43 Trolox equivalents (TEAC)/ g of dried fruit sample and EtOH-H2O extract presented 2.55 ± 2.19 Trolox equivalents (TEAC)/ g of dried fruit sample antioxidant activity.
