THE FATTY ACIDS OF HARE'S-EAR MUSTARD SEED OIL

Abstract

The fatty oil of hare's-ear mustard seed (Conringia orientalis L.) was examined. Constants of the oil were determined and a partial separation of the fatty acids was carried out by the methyl ester fractionation method. Palmitic, oleic, linoleic, eicosenoic, erucic, and lignoceric acids were identified. Erucic acid was found to be present in largest amount. The oil resembles rapeseed and other Cruciferae seed oils in this respect. The content of eicosenoic acid is estimated to be not more than 12% of the total fatty acids.
