Abstract: | Summary Asparagus seed, Mary Washington variety, was found to contain 14.7% of glyceride oil having iodine value 135.1, saponification
value 185.5, and unsaponifiable matter 1.46%. The oil was converted to methyl esters, and the mixed esters were separated
by fractional distillation and low-temperature crystallization. The acids were identified by chemical and physical methods.
The % composition of the fatty acids is estimated from the data as follows: palmitic 3, linoleic 57, oleic 27, stearic 2,
eicosenoic 1.5, arachidic 0.6, undetermined 9. The oil is somewhat similar to corn oil in composition. It has at least 2%
of acids of the C20 series, which have not been reported previously in this plant family (Liliaceae).
