Enantiomeric compositions of monoterpene hydrocarbons in the wood of healthy and top-cut Pinus sylvestris
1993
Sjodin, K. | Persson, M. | Norin, T.
The enantiomeric compositions of seven monoterpene hydrocarbons occurring in Pinus sylvestris L. wood (including bark) before and after top-cutting were determined. The investigation included trees of two chemotypes characterized by high and low 3-carene content, respectively. Top-cutting of the trees caused a weak disturbance in the enantiomeric composition of beta-pinene in trees of the low 3-carene chemotype. The (-)-enantiomer of 3-carene was not detected in any of the specimens investigated. The results and their relation to the biosynthetic pathways proposed for the formation of monoterpene hydrocarbons in higher plants are discussed.
