Apart from that, 8-oxolinalyl acetate was first isolated from lavandin oil and hence reported as a constituent of a natural product (Mookherjee and Trenkle, 1973). Sweet, fruity-floral, rosy, somewhat green and remotely Lavender-like Use: Widely used in floral, fruity, herbaceous, and citrus fragrances.

Retention indices and occurrence of linalool and its derivatives. Geranyl acetate is a monoterpene (a class of terpene that are most often the product of secondary metabolism in plants), and a natural component of over sixty essential ... lavender and geranium flavors to impart a sweet fruity or citrus smell. doi: 10.1002/jssc.200800151, Strauss, C. R., Wilson, B., and Williams, P. J. In preceding weekly training sessions the assessors were trained for at least half a year in recognizing orthonasally about 90 selected known odorants at different concentrations according to their odor qualities and in naming these according to an in-house developed flavor language. Linalool was found to be the most potent odorant among the investigated compounds, with an average OT of 3.2 ng/L, while the 8-hydroxylinalool derivative was the least odorous compound with an OT of 160 ng/L; 8-carboxylinalool was found to be odorless.

Odor qualities for 1 and 2 and their C-8 oxygenated synthesized derivatives were investigated by trained panelists using GC-O, the obtained attributes are shown in Table 2. ERNESTO VENTÓS, S.A. shall not be held responsible for any damage or injury resulting from contact with the above. In perfumery, linalool is a commonly used fragrant ingredient being a component of many perfumes top notes and being found in 60–90% of cosmetic products (Cal and Krzyzaniak, 2006). As shown in Table 2, it is worth mentioning that the attributes provided by 60–70% of the panelists in case of linalool were citrus-like and flowery, whereas soapy was selected by only 37% of the panel as descriptor. Flash chromatographic purification with petroleum ether/diethyl ether 1:4 (v/v) yielded 1.4 g (29%) of 3 as orange oil.1H NMR (600 MHz, CHLOROFORM-d) δ ppm 9.38 (1 H, s), 6.42–6.56 (1 H, m), 5.92 (1 H, dd, J = 17.26, 10.67 Hz), 5.25 (1 H, dd, J = 17.26, 0.91 Hz), 5.11 (1 H, dd, J = 10.90, 0.91 Hz), 2.35–2.45 (2 H, m), 1.74 (3 H, s), 1.61–1.71 (2 H, m), 1.31–1.35 (3 H, m).13C NMR (91 MHz, CHLOROFORM-d) δ ppm 195.2., 154.6, 144.3, 139.2, 112.4, 72.9, 40.3, 28.1, 23.8, 9.1.MS (EI) m/z (%) ( You can’t find what you are looking for? ): 170 [M+] (1), 150(16), 135(13), 131(18), 107(17), 95(25), 82(39), 71(44), 55(28), 43(100). doi: 10.1002/mnfr.201300420, Kessler, A., Villmann, C., Sahin-Nadeem, H., Pischetsrieder, M., and Buettner, A.

The major part of linalool is metabolized by the liver to polar compounds which are mainly excreted in urine as free form or conjugates; only minor amounts are excreted via the feces. doi: 10.1021/jf00081a041. doi: 10.1007/s00217-008-0931-x, d'Acampora Zellner, B., Casilli, A., Dugo, P., Dugo, G., and Mondello, L. (2007). Thereby, one panelist was exceptionally sensitive to all compounds, recording a threshold value as low as 0.6 ng/L for the 8-oxolinalyl acetate, thus, being the lowest threshold value determined within this study (Table 3). doi: 10.1021/jf020845p, Kremer, D., Dunkić, V., Ruščić, M., Matevski, V., Ballian, D., Bogunić, F., et al. Found in various fruit, berry, floral, and spice flavors. Compound 5 (311 mg, 1.46 mmol) was dissolved in methanol (50 ml) and 0.1 M KOH (50 ml) was added (Hasegawa, 1983; Scheme 2). 21, 298–302. In folk medicines as well as aroma therapy, essential oils and fragrance compounds are being used as therapeutic agents for relieving pain, anxiety reduction and energy enhancement (Lahlou, 2004; Kako et al., 2008; Kiecolt-Glaser et al., 2008). This means that the C-3 hydroxy group is the only substituent responsible for the linalool high potency and low threshold value, whereas any substituents on C-8, referring to this study (see Figure 2), especially the aldehydic or the alcoholic functional groups, can still own the same linalool pleasant smell but lack its potency. Sampling flower scent for chromatographic analysis.
