ABSTRACT

Vernonia anthelmintica (L.). Willd. (ironweed) seed from Pakistan or India produced 22\s-28% oil rich in trivernolin, the glyceride of 12,13-epoxyoleic acid, when the highly active lipolytic enzyme was properly controlled. Trivernolin was obtained from the seed as a major end-product without isolation of the oil from the extract in yields of 55\s-60% of the wt of the oil present. Control of lipolysis was achieved, either by a rapid extraction technique where whole seed was flaked as a slurry made of seed and extracting solvent (petroleum naphtha, bp 35\s-59C), or by autoclaving the seed prior to flaking or grinding. An improved quality oil was produced by removal of the major portion of the unsaponifiable material; this upgraded the oil by increasing the epoxy lipid content, decreasing the iodine value (I.V.) and reducing the amount of color and odor.
