Linalool jasmine

Orange Flower. Extraction of freshly picked flowers of the bitter orange tree, dims aurantium (subspecies amard) for the production of concrete is carried out mainly ia Morocco and Tunisia. Most of this material is processed further to give orange flower absolute, one of the most important absolutes used ia perfumes after rose and jasmine. It is highly valued ia perfumery, even when used at low levels, for its long-lasting, rich, warm, yet dehcate and fresh floralcy. The material is a complex mixture, to which methyl anthranilate [134-20-3] linalool (3), methyl jasmonate (15), and iadole (16) are important odor contributors. 

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...

Tea flavor. Primary and secondary flavor compounds (more than 300) contribute to the flavor of black tea, which is otherwise strongly influenced by its origin or production procedures (withering, fermentation, roasting). A major contribution is made by components with flowery notes such as geraniol, linalool, citronel-lol, 2-phenylethanol, and a-//3- ionones, as well as (Z)-jasmone, methyl jasmonate, d- jasmin(c) lactone, and methyl anthranilate as trace components. Green notes such as 2- and 3- hexen-l-ols, (E)-2-... 

Being of high value, jasmine scent excited the interest of chemists at a very early stage. Between 1899 and 1904, Albert Hesse and Friedrich Muller identified more than 70 % by mass of the scented components, including the floral-scented benzyl alcohol, its acetate and benzoate esters, and the lavender perfume, linalool. The characteristic scent of jasmine, however, could not be completely explained (Fig. 3.20).

Z)- and pyranoid 3R,6R)- Z)- and (3S,6S)-(Z)-linalool oxides (8-32) are odorants of jasmine tea, aromatic wines, elderberry bush flowers and linden honey. In grapes, (-)-(Z)-rose oxide from (-)-citroneUol is analogously produced. Rose oxide is also a component of rose and geranium essential oils (8-32). Nerol oxide in rose oil is a racemate. 

The volatile oil (bitter orange oil) contains more than 90% monoterpenes (main f-limonene, also myrcene, campherr pinene, ocimene, p-cymene, etc.) small amounts of alcohols (linalool, terpinene nerol, farnesol, nerolidol, octanol, etc. usually 0.5-1% aldehydes (mainly decanal also nonanal, dodecanal, citronellal, neral acetaldehyde, formaldehyde, etc.), and ketones (carvone, a-ionone, and jasmine) free acids (octadeca-dienoic, pelargonic, cinnamic, acetic, etc.) about 2.4% esters (linalyl acetate, decyl pe-largonate, octyl acetate, geranyl acetate, etc.) coumarins (osthole and auraptenol) and others (jiangsu list and horhammer).
