A New Cardenolide and Other Compounds from Salsola tetragona

Abstract

One new cardenolide, 3- O-β-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.
