Search for new industrial oils. viii. the genuslimnanthes

Seed oils from most of the known species and varieties ofLimnanthes were analyzed for their fatty acid content. Each contained at least 95% acids with more than 18 carbon atoms. The major component acid,cis‐5‐eicosenoic, ranged 52舑77% of the acids present. Seeds of all species examined contained thioglucosidic precursors of volatile isothiocyanates, liberated by the action of mustard seed enzymes on the meal. One species also yielded a small amount of an oxazolidinethione‐like compound of the type associated with enzyme‐treated rapeseed meal.
