The main components of the essential oil from the flower were germacrene-D (21.2%), p-cymene (20.6%), bicyclogermacrene (17.6%), [gamma]-dodecadienolactone (13.7%), and terpinolene (9.4%).
The germacrene-d, [alpha]-pinene, terpinolene, p-cymene, bicyclogermane and limonene compounds were analysed as major components in the essential oils of the plant (Shafaghat et al.
Turpentine is composed of terpenes which mainly consist of the monoterpenes such as alpha-pinene and beta-pinene with small quantities of careen, dipentene, camphene and terpinolene. Turpentine is often replaced by mineral turpentine or other petroleum distillates which are very different chemically.
We also measure the Terpene content (Linalool, Myrcene, Limonene, Terpinolene, a-Pinene, p-Pinene, Humulene, Caryophyllene, and Caryophyllene oxide).").
Studies on peppermint and its species shows that its leaf and essential oil include such components as acetaldehyde, amyl alcohol, esters of mannitol, limonene, pinene, phellandrene, cadinene, pulegone, dimethyl sulfide, alpha-pinene, sabinene, terpinolene, ocimene, gamma-terpinene, alpha- and betathujone, and citronellol.

However, based on previous studies at the same study site, the rain forest produces at least 12 different monoterpene species, including [beta]-ocimene and terpinolene, which are highly reactive with respect to ozone (Jardine et al.
This study evaluated the effect of the monoterpene terpinolene (TPL) (4-isopropylidene-1-methylcyclohexene) (Figure 1B) associated with DCF in acute and chronic inflammatory hyperalgesia.
With respect to crop levels, only three--isobutyl alcohol, terpinolene and diethyl succinate (the latter was only detected in HC treatment)--differed between HC and FC in 2011.
