1992
Rafii, Z. | Cool, L.G. | Zavarin, E.
Mature foliage from 63 trees of seven populations of Cupressus bakeri Jepson was analysed for mono- and sesquiterpenoids by GC. Compositional variability was high with monoterpenoids and moderate with sesquiterpenoids and higher within than between populations in either case. Of the 54 mono- and sesquiterpenoids present, tricyclene, thujene, alpha-pinene, alpha-fenchene, camphene, sabinene, beta-pinene, myrcene, 3-carene, p-cymene, limonene, beta-phellandrene, gamma-terpinene, terpinolene, trans-p-menth-2-ene-1-ol, camphor, terpinen-4-ol, p-cymene-8-ol, bornyl acetate, alpha-cedrene, beta-cedrene, thujopsene, alpha-curcumene, cuparene, calamenene, cedrol, alpha and beta-acorenol, alpha-cadinol and cadalene were identified by GC-MS. In canonical discriminant analysis the populations separated into three groups, the separations obtained did not substantiate the existence of the ssp. matthewsii and typica proposed by Wolf.
