The structures of one major and three minor constituents of sterol fraction of the Cyclamen coum have been established as stigmasterol [(22E)-(24S)-24-ethylcholesta-$Delta^{5,22}$-dien-$beta$-ol] (1), Poriferasterol [(22E)-(24R)-24-ethylcholesta-$Delta^{5,22}$-dien-$3beta$-ol] (2), stigma-or poriferasta-$Delta^{3,5,22}$ triene [(22E)-24-ethylcholesta-$Delta^{3,5,22}$-trien] (3) stigma-or poriferosta- $Delta^{3,5,7,22}$-tetraene [(22E)-24-ethylcholesta-$Delta^{3,5,7,22}$-tetraene] (4) by spectroscopic means (NMR, EI-MS and GC-MS).
