Amino acid composition ofLesquerella seed meals

Seed meals from 14 species ofLesquerella, family Cruciferae, were analyzed for 18 amino acids. Lysine and methionine contents ranged, respectively, from 331 to 440, and 72 to 94 mg. per g. of nitrogen. When compared with 9 species ofBrassica (rape, mustard),Lesquerella seeds were higher in lysine and lower in methionine. Thirteen unidentified substances were detected by the ion‐exchange chromatographic method used to determine amino acids.
