MONOTERPENES FATTY AND RESIN ACIDS OF PINUS LAMBERTIANA AND PINUS MONTICOLA

The sapwood and heartwood of sugar pine (Pinus lambertiana) and western white pine (Pinus monticola) have been examined for monoterpenes, fatty and resin acids. The principal qualitative differences between the terpene composition are the presence of Δ3-carene in significant amounts in sugar pine and its apparent absence in western white pine and the presence of n-decane in western white pine and its absence in sugar pine. While the seldom reported trans-cinnamic acid was found in each of these pines, the recently reported sugar pine resin acid, lambertianic, was not found in western white pine. © 1970.
