Abstract
A mixture of fatty acids (100g.) was obtained from the fruits (1150g.) of Anthriscus sylvestris Hoffm., this mixture being separated into 70g. of solid acids and 18g. of liquid acids. The majority of the solid fatty acids was found to be petroselic acid (I), m. p. 32-33°, the remainder being a small amount of petroselidic acid (II), m. p. 53°. The liquid fatty acids, on oxidation by Hazura's method, yielded a small amount of 6, 7-dihydroxystearic acid, m. p. 122°, and a comparatively large amount of 9, 10, 12, 13-tetrahydroxystearic acid (α-sativlc acid), m. p. 162°, which showed that the majority of the liquid acid is linoleic acid. It is doubtful, however, if petroselidic acid had been contained, per se, in the fruit or whether a portion of petroselic acid had undergone elaidination. This must be confirmed by actual experimentation.
