PADUS VIRGINIANA AS A SOURCE OF BIOLOGICALLY ACTIVE SUBSTANCES
The article presents the results of a study of the content of biologically active substances in the Padus virginiana, which grows on the territory of the Orenburg region. Microscopic analysis of the fruits of the Padus virginiana and the fruits of the Padus avium the same type of anatomical and morphological features. Qualitative analysis of flavonoids, including anthocyanins, and tannins (of a condensed nature). Analysis of the quantitative content of biologically active substances in the fruits of the Padus virginiana revealed that the maximum concentration of the amount of flavonoids and tannins was set in the raw materials collected in the Orenburg region, and the level of anthocyanins in the raw materials harvested in the Tashlin district. Thus, raw Padus virginiana growing in the area of Tashlinskiy rayon, may be considered as a source of anthocyanins, and raw Padus virginiana from the Orenburg district, as a source of tannins and flavonoids.
