Turnip (latin Brassica rapa) is a herbaceous plant from the genus Cruciferous. The root crop is a traditional product that has been producing in Russia since ancient times. This unpretentious herbaceous plant contains many different nutrients. The composition of turnips determines its value as a dietary product. From an economic point of view, the root crop, along with broccoli, can act as a source of biologically active substances like sulforaphane. Processing root crops using extraction will expand the scope of its application. The work presents a laboratory way for producing an extract of sulforaphane, followed by its quantitative determination from turnip varieties Petrovskaya-1. It was shown that the content of sulforaphane turnip extract (0.83 ± 0.03) mg in 1 cm3 extract. Next, the antioxidant ability of the extract was determined. A spectrophotometric study of antioxidant activity using a model adrenaline autooxidation reaction (in vitro) revealed that the aqueous extract has a pronounced antioxidant effect. It was registered that at an exposure time of 5 min, the AOA of the extract was 49.0%, at 10 min it was 13.0%. We can say that the processing of root crops is promising as a source of biologically active substances.
