CYCLOPROPENOID FATTY-ACIDS OF 6 SEED OILS FROM MALVACEAE

Abstract

The seeds of Alyogine hakeifolia, Alyogine huegelii, Gossypium australe, Hibiscus coatesii, Lawrencia viridigrisea and Radyera farragei (Malvaceae) contained 13.5-18.6% oil. Linoleic acid predominated (60.0-68.2%) in the component fatty acids of all the oils, followed by palmitic (9.9-18.1%) and oleic acids (7.8-15.8%). Cyclopropene fatty acids, malvalic and sterculic, were present in small concentrations (1.0-4.4%, 0.1-1.5% respectively). Dihydrosterculic acid was present in small quantities (trace-2.1%).
