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

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

The seed oil of Santalum 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 of trans ‐ximenynic acid was confirmed after isolation by ultraviolet, infrared, and nuclear magnetic reso...

Zusammenfassung:The seed oil of Santalum 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 of trans ‐ximenynic acid was confirmed after isolation by ultraviolet, infrared, and nuclear magnetic resonance (NMR) ( 1 H‐ and 13 C‐) spectroscopy and by gas chromatography/mass spectrometry (GC/MS). The cis isomer of ximenynic acid was also found (
