Abstract

The seed oil of Abutilon indicum (Malvaceae) contains three HBr‐reactive fatty acids. These are shown to be cis‐12,13‐epoxyoleic (vernolic) acid, 1.6% 9,10‐methylene‐octadec‐9‐enoic (sterculic) acid, 0.9%; as well as 8,9‐methylene‐heptadec‐8‐enoic (malvalic) acid, 2.3%. Quantitative results are obtained by combining informations about the HBr‐titration, the preparative thin layer separation of oxygenated and non‐oxygenated acids, and gas liquid chromatographic analysis.

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
