Methyl ricinoleate (1) was treated with bromine and the dibromo derivative (2) was reacted with ethanolic KOH under ultrasonic irradiation to give 12-hydroxy-octadec-9-ynoic acid upon acidification with dil. HCI. The latter compound was methylated with BF3/methanol to give methyl
Triacylglycerols (TAGs) containing less common fatty acids (FAs) were isolated from the seeds of three plants (Santalum album, Crepis foetida, and Leucas aspera). These FAs had allenic (laballenic acid, Lb) and acetylenic (crepenynic, C; ximenynic acids, Xi) bonds. TAGs were analyzed on
