Variability of foliage terpenes of Fitzroya cupressoides

Abstract Foliage of 57 Fitzroya cupressoides trees from six locations in Chile was analysed for monoterpenes and sesquiterpenes. A new monoterpene, ipsdienyl acetate (2-methyl-4-acetoxy-6-methylene-octa-2,7-diene), was found. No geographic variability in monoterpene composition was evident. Three distinct sesquiterpene chemotypes were found in the areas sampled. The basic chemotype produced sizeable amounts of germacrene D, bicyclogermacrene, caryophyllene and several sesquiterpene alcohols including trans -nerolidol. The second chemotype elaborated in addition α-longipinene and an unknown sesquiterpene alcohol, as well as some β-longipinene, which has not been previously reported in higher plants. The third chemotype produced α- and β-acorenol and a number of cedrene-related hydrocarbons. Minor geographic variability in the sesquiterpene composition of the basic chemotype was indicated.
