Polyphenolic compounds (flavonoids) of lyophilized aqueous extracts from Caragana jubata (Pall.) Poir. raw material from 2010 and 2015 were studied using modern HPLC-DAD-MS. Primarily mono- and diglycosides of O-hydroxylated (myricetin, quercetin, kaempferol) and O-methylated flavonols (isorhamnetin, laricitrin, syringetin) were identified. Long-term storage of dried raw material under standard conditions had little effect on the quantitative content of polyphenolic compounds. Acute toxicity studies of C. jubata extract showed no toxicity.
