Sandalwood oil is produced commercially by steam distillation. The average commercial oil yield from S. album varies between four and six percent but individual tree estimates have varied from 0.2 to 7.25 percent. The reported average oil content of S. spicatum is two percent but individual oil content estimates have varied between 0.5 and 6.1 percent.
Such variation in oil content has been attributed to the age of the tree and the site or provenance or the grade of the heartwood. To examine this variation in more detail, a simple method of determining the content of sandalwood oil is required.
In this paper I have presented a method of estimating the content of sandalwood oil and have suggested a way in which the oil content in S. album can be predicted by a simple Soxhlet extraction.
