OCCURRENCE OF TRANS-3-HEXADECENOIC ACID IN A SEED OIL
trans-3-Hexadecenoic acid was found to be a component of the glyceride oil of seeds of Heleniumbigelowii A. Gr. It constituted about 10% of the total fatty acids. The acid was isolated and identified by oxidative cleavage and by its infrared and nuclear magnetic resonance (n.m.r.) spectra. Reaction...

| Zusammenfassung: | trans-3-Hexadecenoic acid was found to be a component of the glyceride oil of seeds of Heleniumbigelowii A. Gr. It constituted about 10% of the total fatty acids. The acid was isolated and identified by oxidative cleavage and by its infrared and nuclear magnetic resonance (n.m.r.) spectra. Reaction with alkaline permanganate gave 3-hydroxypalmito-γ-lactone. Mild alkaline treatment of methyl 2 tyrans-3-hexadecenoate caused a shift of the double bond to the 2-position. A sample of Heleniumhoopesii seed oil did not contain any trans-unsaturated acid. |
