This article reports on the structure of triterpenoids saponins (1–49) isolated from Fagonia species. In addition, it describes one known flavonoid (50) with luteolin as aglycone and seven known triterpenoid saponins (26, 51–56) isolated from the aerial parts of Fagonia scabra Forssk. Compounds 50–56, were isolated for the first time from the genus Fagonia, while compounds 50–53, 55–56 have never been encountered in the Zygophyllaceae family. The chemotaxonomic relationship between F. scabra and other Fagonia species was also discussed.
