Abstract
The triglyceride structure of oil fromLesquerella fendleri, a potential new U.S. crop, rich in C20 hydroxy fatty acids, was examined by silica gel column chromatographic fractionation followed by supercritical fluid chromatography. The analysis confirmed previous findings derived by our research group, but provided further detail. The analysis demonstrated the presence of trihydroxy triglyceride, which contained all of the oil’s C18 hydroxy acyl groups (present at less than 0.5% in the oil). Lipolysis indicated that these groups were located solely at the 2-position. In addition, a strong correlation was detected between the presence of α-linolenic (18:39,12,15) and auricolic (20:211,17 OH14) acids in triglycerides.
