It was described in the previous paper that petroselidic acid was detected in the fruit oil of Anthriscus sylvestyis Hoffm., but that it was unknown whether the acid was contained, per se, in the fruit oil or whether it had been formed from petroselic acid during the extraction process. As a result of subsequent studies on the elaidination of petroselic acid, it was found that this acid underwent elaidination much more easily than oleic acid and, consequently, petroselic acid in the plant gradually underwent elaidination by the irradiation of ultraviolet light. However, elaidination was found not to occur by heating, saponification with alkalis, or by the action of diluted acids. Since the irradiation of ultraviolet light for an extended period failed to yield 100% petroselidic acid, it would be assumed that the fact that some crystals, m. p. 53°, of petroselidic acid had been obtained from the fruit oil of Anthriscus sylvestyis, shows that petroselidic acid is contained, per se, in the fruit oil, even in small quantities.
