Characterization of two steroidal ketones and two isoprenoid alcohols in dairy products
VP Flanagan, A Ferretti, DP Schwartz and JM Ruth
Two steroidal ketones, delta-4-cholesten-3-one and delta-3,-5-
cholestadiene-7-one, were isolated and identified for the first time in
anhydrous milk fat and in nonfat dry milk. Together with these, two
isoprenoid alcohols, phytol and dihydrophytol, were identified in anhydrous
milk fat. Their identities were established on the basis of chromatographic
and mass spectral data and confirmed by comparison with authentic
materials.
