Buckwheat leaf meal fat. II. Composition of the fatty acids

  • Published:
Journal of the American Oil Chemists Society

Summary

The composition of fatty acids of the saponified fat of buckwheat leaf meal was investigated. The mixed fatty acids amounted to 49.6% of the composition of the fat. The chief organic acids found were: linolenic, 15.1%; oleic, 13.1%; linoleic, 8.5%; and palmitic, 8.0%. Less than 1% each of such acids as formic, lactic, stearic, arachidic, hexacosanoic, and octacosanoic, and only traces of acetic, lignoceric, and tricontanoic (or higher) acids were found. The so-called “insoluble acids” of the saponified fat, less the unsaponifiable matter, contained 28.5% (18.5% based on the original fat) of material identified as red pigment and probably a mixture of chlorophyll degradation compounds, chiefly phylloerythrin.
