Isovitexin o-glucosides from Aquilegia vulgaris L.

4'-O-beta-glucopyranoside of isovitexin from the leaves with stems and 4'-O-delta-glucopyranoside of -2"-O-beta-glucopyranosylisovitexin from the flowers of Aquilegia vulgnris L. were isolated. The structures of the compounds were determined by chemical and spectroscopic methods.
