Sterol and Triterpene Diol Contents of Vegetable Oils by High-Resolution Capillary Gas Chromatography

An in-laboratory validated method for identification and quantitation of sterols and triterpene diols was used to determine the relative composition of identifiable sterols and triterpene diols in 13 vegetable oils and quantitate these components in multiple samples of 6 vegetable oils: extra virgin olive, pomace olive, corn, cottonseed, canola, and evening primrose oils. Erythrodiol, a triterpene diol present in all olive oils, was also found in cottonseed oil.
