Characterization and structure elucidation of 12-hydroxyoctadec-cis-9-enoic acid in Jatropha gossypifolia and Hevea brasiliensis seed oils: a rich source of hydroxy fatty acid

摘要

The seed oils containing hydroxy fatty acids are being used in various industries such as, in the production of nylon-11 in the manufacture of multi-purpose greases, as good anti-rust, new additives in water-soluble cutting fluids, and antimicrobial activity of various derivatives of ricinoleic acid polymers. Jatropha gossypifolia and Hevea brasiliensis seed oils were found to contain 18.5% and 18.0% of 12-hydi-oxyoctadec-cis-9-enoic acid (ricinoleic acid), respectively. The identification and characterization was based on UV, MR. H-1 NMR, C-13 NMR, MS, GC analysis and chemical degradations. (c) 2007 Elsevier Ireland Ltd. All rights reserved.
