Isolation of methylcis, cis‐5, 13‐docosadienoate fromLimnanthes douglasii oil

Abstract
Methylcis,cis-5,13-docosadienoate has been isolated from the mixed methyl esters of the fatty acid moiety ofLimnanthes douglasii oil by a combination of low temperature fractional crystallization and fractionation of mercuric acetate adducts. The methyl ester and its free acid have been characterized.
