Fatty Acids in the American Groundnut (Apios americana)

Abstract
The fatty acid profiles of lipids extracted from groundnut (Apios americana Medikus) seeds and tubers were analyzed using gas‐liquid chromatography. Groundnut seeds contained 12.1–18.4% lipids and groundnut tubers 4.1–4.6%, on a dry weight basis. Fatty acid profiles of seed and tuber lipids differred; however, linoleic acid predominated. The fatty acid profiles of seeds and tubers varied between plants collected in two different locations, suggesting genetic variability.
