Industrial utilization of Ri6ea ornata seed oil: a moderate source of vernolic acid
نویسندگان
چکیده
Ri6ea ornata seed oil was found to contain 12,13-epoxy-octadec-cis-9-enoic acid (vernolic acid, 22.0%) along with the other normal fatty acids like palmitic acid (24.2%), stearic acid (8.9%), oleic acid (17.1%) and linoleic acid (27.8%). The identification and characterization was based on Fourier transform infrared (FTIR), H-NMR, mass spectrometry (MS), gas–liquid chromatography (GLC)-techniques and chemical degradations. © 2000 Elsevier Science B.V.

Vernonia oilseed production in the mid-Atlantic region of the United States
Epoxidized oils, manufactured by chemical epoxidation of fats and vegetable oils such as soybean [Glycine max (L.) Merr.], are useful in reformulation of oil based (alkyd-resin) paints to reduce emissions of volatile organic compounds that contribute to production of smog. Other potential markets for epoxy fatty acids include plasticizers, additives to polyvinyl chloride, polymer blends and coa...

INTRODUCTION Recent decades have witnessed an increase in the rate of desertification of agricultural lands. More than one-third of our planet’s land is now arid. Water for crops and an increasing human population is rapidly becoming a critically short commodity. Yet none of the major crop plants of the world is well adapted to arid lands. Efforts have been made to introduce new crops, which ar...
متن کاملTransgenic production of epoxy fatty acids by expression of a cytochrome P450 enzyme from Euphorbia lagascae seed.
Seed oils of a number of Asteraceae and Euphorbiaceae species are enriched in 12-epoxyoctadeca-cis-9-enoic acid (vernolic acid), an unusual 18-carbon Delta(12)-epoxy fatty acid with potential industrial value. It has been previously demonstrated that the epoxy group of vernolic acid is synthesized by the activity of a Delta(12)-oleic acid desaturase-like enzyme in seeds of the Asteraceae Crepis...

Approximately 10-30% of tomatoes are wasted during processing. Tomato pomace consists of crushed skin and seeds of tomatoes. Seeds might be considered as a potential source of vegetable oil. The extracted oil is high in unsaturated fatty acids, namely linoleic acid. The extracted oil after purification or refining might be employed for consumption. The object of this study was to evaluate the e...
