Abstract:
Levels of biologically active and reserve substances were investigated in the leaves and rhizomes of Paeonia anomala L., P. hybrida Pall., and P. lactiflora Pall. The peonies’ leaves are rich in ascorbic acid (1205.7 mg/100g in P. anomala ) and tannins (15.9% in P. lactiflora and 15.7% in P. anomala ) at the beginning of the growth season. Concentrations of flavonols, pectins, and carotenoids in the Siberian peonies are low at the beginning of the growth season. P. lactiflora is a promising species for further research on the set and levels of biologically active and reserve substances in rhizomes because this species stands out among the three Siberian species in terms of the levels of catechins (1297.8 mg/100g), protopectins (10.1%), saponins (19.2%), and sugars (22.1%) in rhizomes. In these parts of the plant, starch (18.6%) accumulates the most in P. hybrida among the studied peonies species. Concentrations of the analyzed substances in the rhizomes of the peonies change significantly by the end of the growth season and vary widely among these species. Levels of ascorbic acid (except for P. hybrida ), protopectins, and starch increase significantly while concentrations of catechins and sugars decrease in the rhizomes by the end of the growth season.
