Abstract
The triglyceride composition ofEphedra nevadensis seed fat, which contains 16 different fatty acids, has been analyzed by a combination of liquid-liquid partition and gas-liquid chromatography. Triglycerides were first separated by liquid-liquid partition chromatography. The recovered fractions were then analyzed by gas-liquid chromatography to determine the molecular weights of the triglycerides present. Consecutive separation by these two techniques resolved this complex seed fat into 30 different triglyceride groups.A method for preparative liquid-liquid partition chromatography of triglycerides is described in detail. Highly unsaturated triglyceride mixtures are easily resolved on the basis of "partition number" by using a hexadecane/nitroethane partition system.
