No. The $250 test covers identity, purity and quantity by a chromatographic assay, with detection selected for the compound. Full testing to the USP Herbal Medicines Compendium monograph for Santalum album oil is available and quoted.
Sandalwood oil is a volatile mixture of sesquiterpene alcohols with little UV absorbance, so the lab uses a detection method suited to the compound. The test also gives a full profile of the oil, which helps spot added materials.
(Z)-α-santalol and (Z)-β-santalol are the main alcohols in true Santalum album oil. Their combined level is the main sign of authentic East Indian sandalwood oil.
Amyris (West Indian sandalwood), Australian sandalwood (Santalum spicatum) and other Santalum or unrelated species oils are common look-alikes. They have a different santalol balance or none at all, which shows up in the chromatographic profile.
