Ximenynic acid is trans-11-octadecen-9-ynoic acid,^[1] a long-chain acetylenic fatty acid.^[1]

It was discovered in the fruit kernels of three species of South American plants in the genus Ximenia, after which it is named.^[2] and found to have the formula C₁₈H₃₀O₂.^[2]

It can be extracted from the fruit kernels of the Santalum obtusifolium (Sandalwood)^[3] and the Australian sandalwood Santalum spicatum^[1]

It is also found in seed oil of other plants in the Santalaceae family, including the native cherry Exocarpos cupressiformis and sweet quandong Santalum acuminatum.^[4]
