“…While VCO consists of mainly -cedrene, -cedrene, thujopsene, cuparene, cedrol and widdrol, VCLO does not contain large amount of these compounds. The studies on composition of VCLO have been generally used for chemosystematic (taxonomic) applications, such as analyses of hybridization and geographic variation [12,17] . Von Rudloff found that VCLO primarily consists of sabinene, limonene, -pinene, -terpinene, terpinolene, 3-carene, myrcene, 4-terpinenol, citronellol, elemol, -, --eudesmal and the aromatic ethers (estragole, safrole, methyl eugenol, methyl citronellate and elemicin) [18] .…”
