Separation and identification of ximenynic acid isomers in the seed oil ofSantalum spicatum R.Br. as their 4,4‐dimethyloxazoline derivatives

Separation and identification of ximenynic acid isomers in the seed oil ofSantalum spicatum R.Br. as their 4,4‐dimethyloxazoline derivatives

The seed oil ofSantalum spicatum contains a significant amount of ximenynic acid,trans‐11‐octadecen‐9‐ynoic acid, a long‐chain acetylenic fatty acid, as a major component (34%). The identity oftrans‐ximenynic acid was confirmed after isolation by ultraviolet, infrared, and nuclear magnetic resonance...

Zusammenfassung:The seed oil ofSantalum spicatum contains a significant amount of ximenynic acid,trans‐11‐octadecen‐9‐ynoic acid, a long‐chain acetylenic fatty acid, as a major component (34%). The identity oftrans‐ximenynic acid was confirmed after isolation by ultraviolet, infrared, and nuclear magnetic resonance (NMR) (1H‐ and13C‐) spectroscopy and by gas chromatography/mass spectrometry (GC/MS). Thecis isomer of ximenynic acid was also found (
