Oil Marjoram

This alcohol is probably identical with the alcohol origanol discovered by Wallach in marjoram oil and termed by him terpineol.

Separation of terpinen-4-ol enantiomers performed by a chiral GC columnand a chiral lanthanide shift reagent Eu(hfc)3, showed that the enantiomeric composition of an isolated compound from sweet marjoram oil was 73% (5)(- -) 27% R) —). The (4f )(—)-enantiomer was found in the oil of Eucalyptus dives Terpinen-4-ol was also found in several bark beetle species and is the main component in the aggregation pheromone of Polygraphuspoligraphus ... 

Marjoram oil (sweet marjoram oil) is obtained by steam distillation of the herb Origanum majorana L. Majorana hortensis Moench, Lamiaceae). It is a yellow to greenish- yellow liquid with a characteristic earthy-spicy odor. 

The main constituent of the oil is l-terpinen-4-ol (>20%), which with (+)-cw-sabinene hydrate [15537-55-0] (3-18%) is responsible for the characteristic flavor and fragrance of marjoram oil [614-620bj. 

Sweet marjoram oil is used mainly for flavoring foods, but also in smaller amounts in perfumery for spicy shadings in men s fragrances. FCT 1976 (14) p.469 [8015-01-8], [84012-24-8],... 

Spanish marjoram oil is distilled from Thymus mastichina L., a wild plant growing in Spain. The oil is a slightly yellow liquid with a fresh camphoraceous odor. Its main constituent is 1,8-cineole (up to 65%).

Marjoram Oil, Spanish Type, occurs as a slightly yellow liquid with a camphoraceous note. It is a volatile oil obtained by steam distillation from the flowering plant Thymus mastichina L. (Fam. Labiatae). It is soluble in most fixed oils, but it is insoluble in glycerin, in propylene glycol, and in mineral oil.

Derivatives of Menthene.— The most important alcohols and ketones derived from the menthene unsaturated group of terpenes are terpineol, di-hydro carveol, di-hydro carvone and pulegone. The first one, the alcohol terpineol, occurs in its dextro form in cardamon oil and marjoram oil, in its leoo form in neroU oil and in its inactive form in cajeput oil. The constitution is proven by Perkin s synthesis from As-tetra-hydro para-toluic acid by means of the Grignard reaction. 

Another interesting example is the breakdown of sabinenehydrate acetate (Fig. 2.29), a typical and important flavour component of marjoram oil. This molecule is easily hydrolysed to sabinenehydrate which is subsequently transformed by dehydration into sabinene, a monoterpene hydrocarbon. Sabinene itself can be isomerised to the more stable terpinenes and terpinolene and even oxidised to terpinene-4-ol. It is clear that this whole reaction chain, which is quantified in Table 2.7 for marjoram oil, means a change in the olfactive property, especially since the sabinenehydrate and its ester are most important for the marjoram oil character.

CompositionMain components are the sabinenes (see thujenes) (ca. 5%), a- (5-10%) and y-terpinenes (seep-menthadienes) (10-15%), cis-sabwewe Aydrate (see thujanoles) (10-15%), and terpinen-4-ol (see p-menthenols) (20-30%) the latter two compounds are mainly responsible for the organoleptic properties of sweet marjoram oil. The (genuine) oil should not be confused with the so-called Spanish oil obtained from Thymus mastichina which contains between 40 and 70%, - cineole.
