A mixture of fatty acids (154g.) was obtained from the fruits (1227g.) of Conium maculatum L. These acids were converted to methyl esters and fractionally distilled into Fraction A, b.p.1 130-148°, and Fraction B, b.p.1 149-152°. Each fraction was divided into solid (67%) and liquid (33%) acids. Fraction A yielded, as a solid acid, petroselic acid, m.p. 32-35°. Fraction B yielded, as a solid, an acid of m.p. 30-31°, corresponding to formula C18H34O2 (_??_=1), elaidination of which gave petroselidic acid, m.p. 53°. From the melting point, the primary acid is assumed to be a mixture, chiefly of petroselic acid containing a small amount of petroselidic acid. The liquid acid yielded, by the Hazura oxidation, 9, 10-dihydroxystearic acid in a small amount, and a comparatively large amount of α-sativic acid. These results show that the said fruit oil contains as fatty acids, a large amount of petroselic acid, with a small amount of oleic and linoleic acids, and a very minute amount of petroselidic acid.
