In common carp (Cyprinus carpio), terpenoids such as menthol, myrcene
and linalool (enantiomeric form not specified) were also reported to act as anesthetics at concentrations X50 mg/L (50, 150, and 200 mg/L, respectively) (3,27).
Consequently, the EO is classified into different chemotypes according to its major constituents: citral, linalool, B-caryophyllene, tagetenone, limonene, carvone, myrcene
, y-terpinene, camphor-1,8-cineole and estragole (STASHENKO et al.
cordata are houttuynum, decanoyl acetaldehyde, myrcene
, undecanone, rutin, hyperoside, quercitrin, quercetin, acetic acid and pyridinamine (Liang et al.
Cardamom has varied essential oils which include such as sabinene, pinene, myrcene
, geraniol, linalool, 1, 8-cineole, limonene and citronellol among others that offer a wide range of benefits for skin, hair and health.
The compounds citral and myrcene
were identified through gas chromatography-mass spectrometry (Shimadzu GCMS QP2010 plus), using a DB-5 chromatographic column.
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 antioxidant activity could be due to the presence of b-pinene, a-pinene, 1, 8-cineole, myrcene
, carvacrol, terpinen-4-ol, isoeugenol and eugenol.
Humulene is often referred to as having the most pleasant aroma, whereas myrcene
is often judged to have a harsh grassy character.
Further, the authors reported that [alpha]-pinene, santene, tricyclene, camphene, [beta]-pinene, myrcene
, [delta]-3-carene, limonene, and bornyl acetate were emitted from the essential oil of A.
