Two new cycloartane-type glycosides, named aquilegiosides A and B, were isolated from the dried aerial parts of Aquilegia flabellata Sieb.et Zucc.var flabellata (Ranunculaceae). Their chemical structures have been characterized as 22S-3β,16α,29-trihydroxy-cycloart-24-en-26,22-olide 3-O-β-D-glucopyranosyl-(1→6)-β-D-glucopyranosyl-(1→2)-α-L-arabinopyranoside and 3-O-β-D-glucopyranosyl-(1→2)-α-L-arabinopyranoside, by chemical and spectroscopic evidence.
