Variation in the Monoterpenes of Pinus Ponderosa Laws

R H Smith. Science. .

Abstract

Wide differences from tree to tree were found in the monoterpene composition of the wood oleoresin of ponderosa pines located in the same geographic area in California. Differences attributable to variation within the tree, to the season of sampling, to the year of sampling, and to methods of analysis by gas chromatography were only slight. There may be an inverse relation between the amounts of Delta(3)(-) carene and beta-pinene in a given tree.
