Abstract

Polyphenols contribute to antioxidant properties of Solanum lycopersicum L. (tomato); plant in which they have demonstrated positive effects of magnetic fields (MF) on germination and productivity. So it was necessary to study the content of polyphenols in tomato fruits from plants irrigated with water treated with static magnetic field (SMF) to 150 mT. A completely randomized experimental design, where the control plants were irrigated with normal water and secondary treatment plants were irrigated with SMF to 150 mT was used. From ripe fruits aqueous ethanolic extracts and Folch mixture (chloroform:methanol, 2:1) were prepared. Total polyphenols were measured by the Folin - Ciocalteu and identified with high performance liquid chromatography (HPLC). Simple classification ANOVA and multiple range comparison with least significant difference were performed. Aqueous extracts had a higher content of polyphenols relative to the ethanol and made with the Folch mixture, with statistically significant differences. All extracts from fruits receiving irrigation with treated water with SMF showed most polyphenols. In aqueous extracts prepared from fruit irrigated with SMF, the polyphenol content was 1,25 times higher compared to the control treatment aqueous extracts. Polyphenols rutin, quercetin and gallic acid were identified, of which has been reported significant contribution in the antioxidant capacity of S. lycopersicum L.
