Flavonoids in the leaves with stems of some species of the Aquilegia L. genus.

Methanolic extracts from the leaves with stems of seven species of Aquilegia L. genus (A. hybrida Scott-Eliot, A. olympica BOISS., A. flabellata SIEB et ZUCC., A. alpina L., A. atrata W.D.J. KOCH, A. vitoleili L., A. caerulea JAMES) were subjected to co-chromatography with the extract and the flavonoids obtained from A. vulgaris L. Moreover, the content of 4'-methoxyapigenin 6-C-glucoside (isocytisoside) was determined spectrophotometrically in these species after chromatographic separation.
