Composition and chemical variability of the oleoresin of Pinus nigra ssp. laricio from Corsica



Composition and chemical variability of the oleoresin of Pinus nigra ssp. laricio from Corsica



Industrial Crops and Products 21(1): 71-79



Eighteen samples of oleoresin of Pinus nigra ssp. laricio were harvested in six locations in Corsica. Eight diterpene acids, six neutral diterpenes and alpha-pinene were identified and their contents calculated by 13C NMR spectroscopy, following a procedure recently developed in our laboratories. The results were submitted to chemometric analysis (k-means and principal component analysis) and two clusters were distinguished with respect to the contents of levopimaric acid and dehydroabietic acid.
