Acetylenic Acids from Fats of the Olacaceae and Santalaceae. IV. 

Hatt, H. H., a. C. K. Triffett, and P. C. Wailes Acetylenic acids from fats of Santalaceae and Olacaceae Seed and root oils of Exocarpus cupressiformis, Aus-trahan J. Chem. 12, 190 (1959). 

The most important monoacetylenic acids are tariric (18 1 6a) and crepenynic (18 2 9cl2a) though other examples have also been recognized. Tariric acid has long been known as a component of seed oils of the Picramnia species. Its isomer, stearolic acid, though easily made in the laboratory from oleic acid, occurs only rarely as a minor component in Santalaceae seed oils where more unsaturated mono- and poly-acetylenic compounds are also present (see below). Two rare acids related to stearolic acid are 17 1 (8 ) and 18 2 (9al7e).
