Abstract
The flavonoid and iridoid content of S.umbrosa from Novosibirsk region, Ulagan district of the Altai Republic and cultivated in vitro has been studied. S. umbrosa is considered rare relic in Siberia. The age peculiarities and the mode of chemical substances accumulation in some organs were taken into account. The flavonoid accumulation in the plant organs fluctuated within the limits of 0.1 to 1.2 percent of air dry weight. The maximum values of the flavonoid content were registered in mature plant leaves, especially in the samples from Novosibirsk region. The amount of iridoids was 4.4
