The Content of Total Ash, Tannins, and Ascorbic Acid in the Above-Ground Organs of Daylily Species

The content of total ash, ascorbic acid, tannins was determined in the leaves and flowers of Hemerocallis species: H. citrina, H. fulva, H. lilio-asphodelus, H. middendorffii, H. minor, cultivated under the conditions of the forest-steppe zone of the Novosibirsk Region. Biochemical parameters were determined during the flowering period in 2022. It has been found that the concentration of tannins, ascorbic acid, total ash in the leaves is 1.3-1.5 times higher than in the flowers. The leaves are distinguished by the highest content of ascorbic acid (11.43-16.35 mg/100 g). The specificity of the content of these substances in plants depending on the species, vegetative and generative organs during the flowering period is noted.
