This work was carried out for the quantitative estimation of phenolic compounds (soluble phenolic compounds, flavonoids such as quercetin, cynaroside, and avicularin) and ascorbic acid level in the aerial plant parts (leaves and stems) of two sage species viz., Salvia tesquicola (dry-steppe sage) and Salvia verticillata (lilac sage) grown in Tatarstan and Crimea, Kazan, Russia respectively. The highest content of phenolic compounds and the ascorbic acid level was reported in the leaves, while the value of these chemical constitutes was lowest in the stems of both species. Further, it has been shown, that these plants are rich in all investigated chemicals but among these Cynaroside and avicularin are the predominated flavonoids (cynaroside, quercetin, and avicularin). The amount of all studied active compounds differed significantly and it depends on the plant organs, species, and place of growth. Further, the results of the study revealed that the content of soluble phenolic compounds in sage plants did not depend on the species and place of growth while the growing conditions had a greater impact on the amount of flavonoids and vitamin C contents.
