ABSTRACT.
Data are provided on the content of microelement composition (Cu, Zn, Mn, Co, Fe, Mg, Ca), flavonoids, ascorbic acid and antioxidant activity in honey stevia leaves. A fairly high content of calcium (1080 mg/100 g), phosphorus (110 mg/100 g), magnesium (32,58 mg/100 g), as well as microelements such as manganese (0,095 mg/100 g), copper (0,026 mg/100 g), iron (0,024 mg/100 g) was revealed. The leaf extract has significant antioxidant activity (111.66 mg/g). The potential of stevia as a natural source of mineral elements and antioxidants in the creation of functional food products has been shown.

KEYWORDS: stevia, mineral elements, antioxidants.
