Chromatography of polar triglycerides on silicic Acid Columns

Triglycerides containing polar fatty acids are resolved by silicic acid chromatography into molecular species containing increased amounts of the polar acids. Natural fats like isano, oiticica, castor, or kamala seed oils with both nonpolar fatty acids and polar hydroxy or keto acids have been resolved into component glycerides according to the degree of polarity. Silicic acid chromatography offers a means of obtaining specific glycerides from fats for detailed studies on glyceride composition and structure.
