Abstract (english)

In this paper, the total phenol content and antioxidant capacity of herbal spirit were examined. Pomace brandy, alcohol strength of 50% vol., was used for the maceration of 11 wild Mediterranean plants. The following were analyzed: alcoholic strength, total acidity and total esters of base brandy. Spectrophotometric methods were used to determine: the content of total phenols (Folin-Ciocalteu method) and antioxidant capacity (ABTS method). The highest content of total phenols and antioxidant capacity was obtained in St. John's wort (158 GAE mg/L; 1.089 mM TE). Macerates of thyme, rosemary and yarrow showed significant proportions of analyzed bioactive substances. In the macerate of a mixture of 11 plants, a high positive correlation of the measured bioactive substances for the tested macerate was obtained by statistical data processing (ANOVA, SAS). The results of the work can be used in the selection of plants for the creation of herbal brandy with optimal medicinal properties.
