A New Cardenolide and Other Compounds from Salsola tetragona.

One new cardenolide, 3-O-ß-D-allopyranosylcoroglaucigenin (salsotetragonin) (1), was isolated from the aerial parts of Salsola tetragona Delile with four known cardenolides (2-5); two known flavonoids (6-7), three known phenolic compounds (8-10) and two known fatty acids (11-12). Their structures were identified by spectroscopic analyses and by comparison of their spectral data with those reported in the literature. Compounds 1-5, 7, 10 and 12 were isolated from the genus Salsola for the first time. This is the first report on cardenolides identified in the Amaranthaceae family.
