The seed oil of Hibiscus mutabilis (Chameleon rose) (Malvaceae) contains three HBr-reactive fatty acids. These are found to be cis-l2,13-epoxyoleic (vernolic) acid, 5.9%; 9,10-methylene-octadec-9-enoic (sterculic) acid, 7.3%; as well a s 8,9-methylene-heptadec-8-enoic (malvalic) acid, 14.0%. Co-occu
Seed oil of Sonchus oleraceuc (Compositae) contains &-12,13-ep oxyoctadec-cis-9-enoic acid (Vemolic, 13.7%). Structural details of this HBr-reactive acid are obtained through comparative chromatographic, spectral and chemical data with those of pure vemolic acid isolated from Vmonia anthelmintica se
The seed oil of Acacia s u m (Leguminosae) was found to have a HBr-reactive fatty acid along with other usual fatty acids. On the basis of chemical, spectroscopic and chromatographic techniques the HBr-reactive acid was identified as ci-9,lO-epoxy-cis-12-octadecenoic (coronaric) acid. This acid make
