The sterols and tetracyclic triterpenoids of Digitalis purpurea L. seeds.
TL;DR: Three types of sterols were isolated from the non‐saponified fraction of D. purpurea seed oil by combination of t.l.c., g.c. and mass spectrometry and consisted of cholesterol, campesterol, stigmasterol, β‐sitosterol, fucosterol and 28‐isofucosterols.
