Eight new guaianolide type glycosides, ixerins M, N, O, P, Q, R, S and T, in addition to 8-epidesacylcynaropicrin-glucoside and macrocliniside A, have been isolated from the methanol extract of lxeris stolonifera A. GRAY (Compositae). The structures of the new compounds were determined on the basis of chemical and spectral data.
