摘要: Resume Apres application de methylene-24[23,25-3H3] dihydrolanosterol (I) a des feuilles d'epinard Spinacea oleracea, on isole un melange sterols radioactifs contenant environ 42 pour cent d'α-spinasterol (II). Cette experience confirme qu'une substance ayant methylene en 24 peut etre le substrat la deuxieme etape C-methylation, conduisant chaine laterale ethylidene, ou ethyle phytosterols.
