Total sterols were analyzed from 28 species of Phytolaccaceae and from 29 species of closely related families—Basellaceae, Portulaccaceae, Molluginaceae, and Stegnospermataceae. Eighteen of twenty‐eight species of Phytolaccaceae contained dominant Δ 7 ‐sterols while six species had dominant Δ 5 ‐sterols. Three species had dominant Δ 0 ‐sterols. Sterol composition strongly reflected taxonomic position. Nineteen of twenty‐nine species from Basellaceae, Portulaccaceae, Molluginaceae, and Stegnospermataceae contained dominant Δ 7 ‐sterols while ten species contained dominant Δ 5 ‐sterols. Until recently Δ 7 ‐sterols were considered rare in higher plants. It appears that a large number of species in the order Caryophyllales contain primarily Δ 7 ‐sterols.
