The fatty acids of a sample of filbert (Corylus avellana) kernel oil were examined by means of ester distillation and low-temp. crystallization. Stearic, oleic, and linoleic acids were identified but eicosenoic acid was not found although earlier workers had reported its presence in considerable amt. in samples from the same spp. Nasturtium (Tropaeolum majus var.) seed oil, examined in the same way, was found to contain about 20% of 11-eicosenoic acid. An estimate is given of the fatty acid composition of the 2 oils.
