The phytochemical investigation of the ethyl acetate soluble fraction of the whole plant of Pulicaria undulata L. (syn. Pulicaria crispa Forssk.) yielded two new flavonoid glycosides, pulicaroside (1) and undulatoside (6) along with four known flavonones (2-5). The structures of the new compounds were identified by 1D and 2D-NMR techniques along with other spectral evidences and by the comparison with the published data of the closely related compounds. All the flavonoids (1-6) exhibited superoxide anion scavenging activity.
