    Abstract: We measured the constituent triacylglycerol of cotton oil, the only edible oil containing a cyclo fatty acid. Due to the difficulty of obtaining a standard for triacylglycerols containing cyclo fatty acids, cotton oil is analyzed using cyclo triacylglycerol in kapok oil as a reference. Analytical methods used liquid chromatography fast atom bombard... Show More
