Abstract

By saponification and extraction of corn oil foots abandoned as waste during oil refining, a mixture of phytosterols was obtained, and its major components were determined as .betha.-sitosterol, campesterol and stigmasterol by gas chromatographic analysis. The mixture is very cheap and regarded as an excellent substrate for direct fermentation of C-17 keto steroid intermediate for various steroid pharmaceuticals.
