A recent survey about essential oils and their pure constituents used to control Varroa jacobsoni, contained three interesting tables that reported the toxicity of essential oils for V. jacobsoni and Apis mellifera after 24, 48 and 72 hours in a topical application and in an evaporation test, and the effects of essential oils on behavior and reproduction of V jacobsoni and on the bee brood [63]. The most interesting oils were those of cinnamon and clove, with 100% mite mortality after 24 h and no significant toxicity on honey bees. Furthermore, clove essential oil produced small brood mortality, and it was an inhibitor of mite reproduction. Other effective oils were anise, fennel, lavender, rosemary and wintergreen, which killed 100% mites after 48-72 hours. On the contrary, the oils obtained from garlic, onion, oregano and thyme, were found to be very toxic for honey bees. Among pure constituents, camphor, linalool, linalyl acetate and pinene resulted small brood mortality and inhibited mite reproduction. 

Among well-known spice allergens are diallyl disulfide and Allicin (garlic allergens, Allium sativum), eugol (nutmeg, cloves, and Jamaica pepper), cinnamic aldehyde (cinnamon), dipentene (caraway, cardamom, and spearmint), and linalool (basilica, coriander) (Kanerva 2002). 

Higher oil content was reported in cinnamon leaf from Hyderabad (4.7%) compared with that from Bangalore (1.8%) (Mallavarapu et al., 1995). The two oils were of eugenol type and differed with respect to the relative amounts of linalool, cinnamal-dehyde, cinnamyl alcohol, cinnamyl acetate and benzyl benzoate. The essential oil of the leaves of C. zeylanicum from Cameroon contained eugenol (85.2%), (EJ-cinnamaldohyde (4.9%), linalool (2.8%) and /3-caryophyllene (1.8%) (Jirovetz et al., 1998).

CIC The typical basic exotic green note is produced by methyl-2-hexenoate and methyl hexanoate. Ciimamyl alcohol and methyl ciimamate add the spicy cinnamon note and linalool together with benzyl acetate form the basic floral, perfumistic background. 

Ceylon cinnamon oil (1) shows an additional violet-blue zone at U, 0.2, a blue zone at R, 0.4 (linalool/Tl), and the terpene ester at R, - 0.65. 

C. verum cinnamon bark oil contains as its major component cinnamic aldehyde (usually 60-80%) other major constituents include sesquiterpenoids (4-5%) (e.g., a-humulene and P-caryophyllene that make up 3-4% of the total, limonene, and others), eugenol, eu-genol acetate, cinnamyl acetate, cinnamyl alcohol, methyl eugenol, benzaldehyde, cu-minaldehyde, benzyl benzoate, monoterpenes (e.g., linalool, pinene, phellandrene, and cym-ene), carophyllene, safrole, and others (list AND horhammer MASADA RAVINDRAN). °... 

C. verum leaf oil contains high concentrations of eugenol (Ceylon type 80-88% Seychelles type 87-96%) it also contains many of the major constituents present in cinnamon bark oil (e.g., benzyl benzoate (6%), cinnamaldehyde, cinnamyl acetate, eugenol acetate, benzaldehyde, linalool, a-ter-pinene, and others), as well as other minor compounds, including a-humulene, 3-caryo-phyllene, a-ylangene, methyl cinnamate, and cinnamyl acetate (masada ravindran). °... 

The SRP N = 25) evaluated all of the solutions described in Experiment 1 by using the audio method for intensity profiling [6]. Two procedures, defined by Lawless et al. [3] as either simple contrast or reversed-pair contrast, were followed, with the exception that only one combination of procedure and condition occurred in any given session. Thus, for the contrast procedure either condition HM or condition LM was used for the reversed-pair procedure, either condition MH or ML. Samples (15mL) were served under red lighting in plastic cups coded with three-digit numbers. Panelists emptied the entire contents of each sample into their mouths and swallowed the solutions. The descriptors for which retronasal flavor intensity was measured were candy (amyl acetate), green (c -3-hexenol), fruity (ethyl butyrate), linalool (linalool), and cinnamon metallic (methyl cinnamate).
