Abstract
AbstractThe seed fats of Carica papaya, Shorea robusta, Hydnocarpus wightiana and Argemone mexicana were hydrolysed with pancreatic lipase and the fatty acid compositions of the liberated monoglycerides, as well as of the original triglycerides were determined by gas‐liquid chromatography. the glyceride compositions were calculated according to various theories using a digital computer. Experimental values for the positional isomers do not agree with random and restricted random values except in the case of H. wightiana oil. In the case of A. mexicana and S. robusta fats the experimental values for all the glyceride types agree with the values according to F. D. Gunstone. In the 2‐positions of the respective triglycerides, linoleic acid predominated over oleic acid in C. papaya, oleic over linoleic in S. robusta and A. mexicana, and hydnocarpic over other long‐chain cyclopentenyl acids in H. wightiana.
