The aim of this study was to assess the activity of extracts from A. DC () in a model of chronic bronchitis in rats. The research was carried out on three water extracts: E1 - from roots of field cultivated ; E2 - from biotransformed roots of ; E3 - from callus of The extracts differed in saponins and inulin levels-the highest was measured in E3 and the lowest in E1.

Biotransformation of cinnamyl alcohol to rosavins by non-transformed wild type and hairy root cultures of Rhodiola kirilowii.

Non-transformed wild type (NTWT) and hairy root cultures of Rhodiola kirilowii were grown in medium supplemented with 2.5 mM cinnamyl alcohol as a precursor and/or sucrose (1 %) on the day of inoculation or on the 14th day of culture. Rosarin, rosavin, and rosin were produced by NTWT root culture but only rosarin and rosavin by hairy roots.
