In specially tavouni.tile situations the hii/ttradi r predominates, in others the latter is found mixed with thesweel orange and with anolher species called /Uiesiii, which is a variety of the two first-named. This species is used pretcrably tor the manufacture of petit-grain oil. [Pg.436]

Methyl anthranilate 172 (Structure 4.51) is found in the oils of sweet orange, lemon, mandarin, bergamot, neroli and ylang-ylang oils and jasmine and tuberose absolutes. Methyl N-methyl anthranilate 173 is the main constituent of mandarin petit grain oil, and occurs also in bitter orange, mandarin and rue oils. [Pg.68]

The ester number for any essential oil may vary within more or less wide limits (see Table XXXIV), but its determination is of importance in the identification of an oil, the detection of adulteration, and for judging of the quality of the oil. With some oils, the esters represent the odoriferous principle, e.g., linalyl acetate in bergamot, lavender and petit-grain oils, bomyl acetate in pine-needle oil and menthyl acetate in mint oil, the value of these Oils being deduced from the ester content. [Pg.279]

Bergamot oil (8) also has linalyl acetate and linalool as major compounds, whereas petit grain oil (9) contains mainly linalyl acetate besides a minor terpene alcohol (Rf 0.15). [Pg.182]

Sesquiterpenic alcohols Examples of sesquiterpenic alicyclic alcohols (8-24) are farnesol and nerolidol (also known as peruviol). Both alcohols, smelling of flowers, are components of many essential oils used in perfumery. Of the four possible geometric isomers, the (2 ,6B)-isomer of farnesol, is the most common in nature and occurs, for example, in basil oil and ambrette (Abelmoschus moschatus Malvaceae) seed oil. The (2Z,6 )-isomer occurs in the petit grain oil bigarade, which is derived from the bitter orange tree leaves (Citrus aurantiumvai. amara, Rutaceae). Farnesol is a natural pesticide for mites and a pheromone for several species of insects. Nerolidol with a double bond at C-6 occurs in the form of (Z)- and ( )-isomers, each of which can exist as an enantiomeric pair (chiral carbon C-3). The individual enantiomers and their mixtures are found in many essential oils. For example, the essential oil known as cabreuva oil that is used in perfumery is obtained from the bark of the South American tree Myrocarpus frondosus (Fabaceae) and contains the (-F)-(E)-isomer of nerolidol (3S,6 )-nerolidol. [Pg.530]

The best petit-grain oil is distilled in the south of France, a certain amount also in Algeria and Spain, and a large amount of less perfume value is distilled in Paraguay, which form the bulk of the oil of commerce. [Pg.436]

During the past few years a number of samples of Paraguay petit-grain oil nave been found which had an optical rotation up to -i- 8° or + 9°. This appears to be due to the distillation material containing small, immature fruits, the essential oil of which contains much dextro-limonene. Normal Paraguay petit-grain oil has the following characters —... [Pg.436]

It is obvious that the W. Indian sample is not a normal petit-grain oil at all, but has been distilled chiefly from immature orange fruits. [Pg.437]

An oil distilled from the unripe orange fruits, analogous to the old-fashioned petit-grain oil, is manufactured and offered under the name of oil of orange peas . Its specific gravity is about 852 to "854 and its optical rotation + 75°. It is interm iate in composition between orange oil and neroh oil. It contains methyl-anthranilate and also traces of a pyrrol compound. [Pg.438]

Umney and Bennett have examined a Buenos Ayres oil resembling ordinary South American petit-grain oil, but having more free alcohols and less esters than those oils. Pinene, dipentene, furfural, geraniol, linalol, and geranyl acetate were found to be present. Its specific gravity was 0 887, optical rotation + 2, esters 36 5 per cent., and free alcohols as geraniol 38 4 per cent. [Pg.438]

Petit-grain oil contains oamphene, /8-pinene, dipentene, limonene, 1-linalol, d-a-terpineol, geraniol, esters of linalol and geraniol, a sesquiterpene, and methyl anthranilate. [Pg.439]
