It was discovered in the fruit kernels of 3 South American ximenia species (and so 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]
