Santalum spicatum

From the oil of Santalum spicatum (R.Br.) A.DC., Birch et al have isolated the two isomeric dihydrofarnesenes (1) and (2). These two compounds, although not identical with the trail pheromone of the Nasutitermes species of termites, both exhibit similar specific trail activities. Cavill and Coggiola have reported that the photosensitized oxygenation of a-farnesene (3) yields the five allylic alcohols (4)—(8) after reduction of the corresponding hydroperoxides. A new...

For the oils tested against Culex quinquefasciatus, the MPTs ranged from 20 to 100 minutes with the longest, 100 minutes, provided by Corymbia citriodora, which was significantly (FIO, 32 = 4.46, p = 0.002) greater than Prostanthera melissifolia, Agonisfragrans, Eucalyptus polybractea. Eucalyptus radiata, Melaleuca ericifolia, Melaleuca quinquenervia, and Santalum spicatum. 

Other terpene alcohols include geraniol, citronellol from rose oil, Rosa gallica (Rosaceae), and scented geraniums Pelargonium spp. (Geraniaceae). Nerol is a stereoisomer of geraniol. Borneol is found in rosemary oil—Rosmarinus officinalis (Lamiaceae). Santalol from heartwood of sandalwood—Santalum album, S. spicatum (Santa-laceae)—is a sesquiterpene alcohol.
