Lavender aroma

Studies with essential oils in human beings have also shown beneficial effects. For instance, anxiolytic effects were observed in patients awaiting dental care treatment in a waiting room previously aromatized with essential oils from Citrus sinensis (L.) Osbeck [378]. In another controlled study, 14 patients undergoing hemodyalisis benefited from hiba and lavender aromas and presented a feeling of calm [379]. Several studies on aromatherapy have attracted the attention of researchers in a study of chemical, pharmacological, and therapeutic properties of these substances [380].

Aroma chemicals are isolates, or chemically treated oils or components of oils. Some components are removed physically, others chemically. In most cases, they are further purified by distillation. For example, Bois de Rose (rosewood) oil may be distilled to isolate linalool, which may be then further treated chemically to yield derivatives such as linalyl acetate, an important fragrance ingredient and a primary component in its own right of lavender and lavandin oils. Vetiver oil Haiti, although containing only 70% alcohols, is treated with acetic anhydride, then carefully distilled to include valuable odor components in the distillate, even though they may not be esters.

Uq 1.4378, may occur in the optically active form. It is found, for example, in lavender oil and is a steam-volatile component of mushrooms. l-Octen-3-ol is a liquid with an intense mushroom, forest-earthy odor that can be prepared by a Grignard reaction from vinylmagnesium bromide and hexanal. It is used in lavender compositions and in mushroom aromas. 

The oil of the lavender plant (Figure 3.1) has been shown to calm the activity of the central nervous system in a fashion similar to stronger prescription tranquilizers, such as benzodiazepines and barbiturates. Lavender is usually put into teas or into candles to create an aroma that is inhaled to produce relaxation and improve the quality of sleep.

Lavender (Lavandula vera DC) honey is highly valued. It is of a golden color and has a delicate aroma. 

Produced by steam distillation from the black peppercorns, the essential oil is water-white to pale olive in colour, with a warm, spicy (peppery), fresh aroma. It has a middle note and blends well with rose, rosemary, marjoram, frankincense, olibanum, sandalwood and lavender however, it should be used in small amounts only (Borges et al., 2003).

Alkanones (C3-C15) have been found in the volatile fractions of many fruits and foodstuffs, but they do not contribute significantly to their aroma. An exception are the odd-numbered methyl ketones C7, C9, Cn which possess a characteristic nutty note they are used, e.g., in cheese flavor compositions. In perfumery, aliphatic ketones are used for accentuation, e.g., 3-octanone [106-68-3] for lavender notes. The hydroxyketone acetoin and the diketone 2,3-butanedione are commercially important aroma substances.

Conifer wood, balm trees, citrus fruits, coriander, eucalyptus, lavender, lemon grass, lilies, carnation, caraway, peppermint species, roses, rosemary, sage, thyme, violet and many other plants or parts of those (roots, rhizomes, stems, leaves, blossoms, fruits, seed) are well known to smell pleasantly, to taste spicy, or to exhibit specific pharmacological activities. Terpenes predominantly shape these properties. In order to enrich terpenes, the plants are carved, e.g. for the production of incense or myrrh from balm trees usually, however, terpenes are extracted or steam distilled, e.g. for the recovery of the precious oil of the blossoms of specific fragrant roses. These extracts and steam distillates, known as ethereal or essential oils ("essence absolue") are used to create fine perfumes, to refine the flavor and the aroma of food and drinks and to produce medicines of plant origin (phytopharmaca). 

Paradoxically, the pleasant aroma of lavender makes the scientific stndy of its effects quite difficult. It is next to impossible to carry out a placebo-controlled test, as the characteristic scent makes the presence of the active ingredient obvious. The effect of lavender oil in bath water or massage oil was also investigated in a handfnl of studies, and these also turned out to be positive. In addition, EEG tests have also proved the oil s effects on the central nervous system.

Most esters are formed by reaction of terpene alcohols with acetic acid. They are among the most widespread volatile oil compounds— being found mainly in flowers— however, they are generally present in small amounts. Their distinctively fragrant aromas characterise many of the oils in which they appear. Lavender oil contains the alcohol linalool along with its ester linalyl acetate the relative abundance of these two constiments is considered to be an indicator of high quality. 

The rst commercial scent production was produced in the United Kingdom, in Mitcham, Surrey, in the seventeenth century, using lavender (Festing, 1989). In 1865, cinnamaldehyde, the rst synthetic, was made. Adulteration and substitution by the essential oil or component of another plant species became rampant. Aroma chemicals synthesized from coal, petroleum by products, and terpenes are much cheaper than the equivalent plant products, so perfumes became cheap.
