The enantiomeric differentiation of linalool is useful in the quality control of essential oils and oleoresins, as it was found to provide an important indication of the authenticity of many herbs and spices. The enantiomeric composition of linalool has been determined in many essential oils, including basil, bergamot, rosemary, lavandin, lavender, balm, coriander, mace. Pelargonium, rose, Cymbopogon, lemon, mandarin, Osman-thus, davana, jasmine, Lippia alba and orange, as well as in many fruit...

P-Citronellol (= 3,7-Dimethyl-6-octen-l-ol) (monoterpene) Pelargonium odoratissimum (Geraniaceae), Rosa damascena, R. gallica (Rosaceae), Boronia citriodora (boronia leaf oil) (Rutaceae) OD-R... 

The direct 5-magnesiation of 2,2-dimethylbenzo-l,3-dioxin-4-one features in the synthesis of 6-hexylsalicylic acid, a component of the essential oil of Pelargonium sidoides DC <07AG(E)7681>. 

For the same subspecies of Mentha they also found almost enantiomerically pure (-)-menthone and (+)-isomenthone. Reversely in Geranium Bourbon (Pelargonium graveolens) oils practically pure enantiomer of (-)-isomenthone has been accompanied with (+)-menthone [37,45]. 

The worker in the essential oils soon learns that commercial geranium oils are extracted from several species, varieties, and strains of Pelargonium and not from Geranium... 

C oH,gO, Mr 154.25, liquid. Monocyclic monoter-pene ketones, the four optically active forms occur in nature. (-)-M. (ca. 35%) occurs in the essential oil of field mint (Mentha arvensis, Lamiaceae), (-i-)-M. in Micromelia biflora (Lamiaceae) ca. 56%, (-i-)-iso-M. in Micromelia abyssinica ca. 42%, and (-)-iso-M. in geranium oil (Pelargonium spp., Geraniaceae). p-M. is used in perfumes as a mixture with other fragrance substances. 

Approximately 1500 monoterpenes are documented Most of these are linked in the head-to-tail manner and are derived from 2,6-dimethyloctane. (i )-3,7-Di-methyloctanol is a component of the nicely flowery to minty smelling geranium oil obtained from Pelargonium graeveolens (Geraniaeeae). 2,6-Dimethyloctanoic acid occurs in the feather wax of several birds. 

Well-known eudesmane derivatives in flavors and fragrances include a- and p-selinene from the oils of Cannabis saliva var. indica (Moraceae), celery (Apium graeveolens, Umbelliferae) and hops (Humulus lupulus, Moraceae), (+)-a- and (+)-P-eudesmol from some oils of eucalyptus (Eucalyplus macarlhuri), (-)-epi-y-eudesmol with its woody odor from the north African oil of geranium (Pelargonium odoralissimum and allied species), and the almost odorless diastereomeric (+)-y-eudesmol from various ethereal oils (+)-p-Costus acid and (+)-p-costol belong to the constituents of the essential oil obtained from the roots of Saussurea...
