Sterol Content Determination in Wheat Flour.

Determination was made of sterol content in wheat flour. Based on direct GC-MS comparison with authentic samples and mass spectral data, fifteen 4-desmethylsterols, four 4-monomethylsterols and two 4,4-dimethylsterols, were confirmed present in the flour, along with three terpene alcohols, and the amount of each was computed. The content of each of five major 4-desmethylsterols (campesterol, campestanol, stigmasterol, sitosterol and sitostanol) in the flour and wheat seeds was determined by GC.
