The contents of the major groups of biologically active compounds (catechins, flavonoids, tannins, saponins, pectin, and carotenoids) and total antioxidants (TA) in the leaves and the flowers of Agastahe rugosa_(Fisch. & C.A. Mey.) Kuntze, Betonica officinalis L., Dracocephalum nutans L., Mentha caucasica Gand., Nepeta grandiflora M. Bieb., Origanum vulgare L., Scutellaria baicalensis Georgi (Lamiaceae), collected during the flowering period of 2019 in “Collections of living plants indoors and outdoors” USU 440534 of Central Siberian Botanical Garden SB RAS, Novosibirsk, were studied. The concentrations of constituent majority were higher in leaves compared to flowers. In the leaves, maximums of catechins (15.60 mg-g-1, B. officinalis), flavonoids (61.5 mg-g-1, S. baicalensis), saponins (178.5 mg-g-1, D. nutans), and protopectin (106.0 mg g-1, B. officinalis) were revealed. In the flowers, maximums of tannins (247.4 mg g-1, O. vulgare) and pectin (16.31 mg g-1, S. baicalensis) were found. Maximum of total antioxidant contents (TAC) (6.21 mgg-1) was detected in the leaves of O. vulgare. Positive correlations between TAC and the content of tannins and flavonoids were revealed. The results confirm health benefits of the studied species and contribute to the knowledge of the distribution of saponins and pectins in the Lamiaceae.
