Summary Freshly dehydrated alfalfa leaf meal was repeatedly extracted with acetone, ethyl alcohol, and Skellysolve B in a percolator at room temperature; 6.59% of crude extract was obtained. This extract was composed of 3.7% phospholipids, 33.2% triglycerides, 17.2% crude wax, 8.3% unsaponifiable, and 37.6% water soluble material. Spectrophotometric analysis of the mixed methyl esters from the triglyceride fraction indicated the presence of 32.2% linolenic, 16.9% linoleic, 31.0% oleic, and 19.9% saturated acids. The mixed methyl esters from the phospholipid fraction contained 35.2% linolenic, 14.7% linoleic, 36.8% oleic, and 13.3% saturated acids.
