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.

This research was aimed at the pharmacological analysis of dermotropic activity ofCaragana jubata (Pall.) poiraqueous extract on the model of atopic contact dermatitis induced by 2,4-dinitrochlorobenzene in male rats. It was found that the aqueous C. jubata extract exhibited expressed dermotropic activity as manifested by reducing thickness of the skin fold by 47% (p = 0.05) and decreasing severity of the onset of contact dermatitis on the average by 38% (p = 0.05). Histological examination showed positive trends in the regeneration of skin lesion. Hematologic examination showed normalization of peripheral blood parameters in animals affected by contact dermatitis. Calculations of the index of inhibition of the inflammatory response confirmed anti-inflammatory effect of the aqueous C. jubata extract.
