• Abstract Twenty‐one species in the Chenopodiaceae were analyzed for sterol composition. In ten of eleven species of Chenopodium , the major desmethylsterols were Δ 7 ‐sterols accompanied by lower proportions of Δ 5 ‐sterols. In C. fremontii this pattern was reversed. The sterol profiles of five species of Atriplex were characterized by the coexistence of Δ 7 ‐ and Δ 5 ‐sterols in ratios of 0.3∶1 to 0.4∶1. Male Atriplex plants contained higher proportions of Δ 5 ‐sterols than female Atriplex plants. One Ceratoides and two Salicornia species contained Δ 5 ‐sterols as their predominant sterols.
