FERRER-DUBOIS, Albys E et al. Phytochemical determination of Solanum lycopersicum L. fruits irrigated with water treated with static magnetic field. Rev Cub Quim [online]. 2018, vol.30, n.2, pp.232-242. ISSN 2224-5421.

The phytochemical compounds of Solanum lycopersicum L. fruits from irrigated plants under the action of water treated with a static magnetic field (SMF), between 20 and 200 mT were determined. Two experimental groups with 25 plants each were used. The control group received irrigation with untreated water and the other group was irrigated with water treated with SMF. The ripe fruits were harvested and aqueous and ethanolic extracts were prepared. These extracts were subjected to phytochemical screening. The aqueous extracts prepared from the irrigated fruits of the group with SMF showed qualitatively a marked presence of carotenoids, phenols, tannins, carbohydrates and flavonoids. These results showed that the SMF used favors the greater extraction of these metabolites which have a high nutritional value and antioxidant potential, which contributes to the pharmacological properties of the fruits of S. lycopersicum L.
