The main constituents of EOLs are the monoterpenoids thymol, p-cymene and myrcene, and the sesquiterpene caryophyllene
From air-dried aerial parts (from Brazil) were obtained the terpenoids phytene, caryophyllene
, germacrene D, bicyclogermacrene, [alpha]- and [gamma]-humulene, squalene, lupeyl acetate, lupeol, [beta]-amyrin and the diacetylenic compound lachnophyllum ester (Bohlmann, Kramp, Grenz, Robinson, & King, 1981), whereas the study of Kuroyanagi, Uchida, Ueno, Satake, and Shimomura (1993) afforded 24 neo-clerodane type diterpenes, many of them new.
14] Some of the chemical compounds found in cloves include Eugenol, Eugenol acetyl, [beta]-caryophyllene
, vanillin, tannins, methyl salicylate, alpha and beta sesquiterpenes, caryophyllene
, glutamic acid, and calcium oxalate.
In this study, five terpenes were identified as fkmyrcene, D-limonene, linalool, eugenol, and caryophyllene
Ylang Ylang has a romantic, flora aroma that consists of several components, including benzyl acetate, benzyl benzoate linalool, caryophyllene
, among many others.
The highest content of the compound in the volatile oil is Caryophyllene
Proof of the natural existence of caryophyllene
in the essential oil of Achyrocline satureioides.
Terpenoids present in essential oils have shown strong repellent or insecticide activity, including hydrogenated monoterpenoids, such as thymol, [alpha]-pinene, carvacrol, myrcene, and oxygenated sesquiterpenes as caryophyllene
oxide (Kim et al.
The sesquiterpenes caryophyllene
epoxide, and nerolidol, reported in extracts of Hymenaea coubaril L.
1999) conducted a study on Psidium guajava plant through GC-MS and they observed the presence of majority compounds, such as caryophyllene
The literature points to caryophyllene
and eugenol acetate as molecules with relative abundancy in this type of matrix.
