Abstract
The composition of the mono- and sesquiterpenoids of the oleoresin of two species of conifers of thePinaceae family has been studied. In the oleoresin ofPinus koraiensis Sieb. et Zucc. 10 oxidized monoterpenoids, 18 sesquiterpene hydrocarbons, and six sesquiterpene alcohols have been identified. In theoleoresin ofPinus pumila (Pall.) Rg1. 10 monoterpene hydrocarbons, six oxidized monoterpenoids, 14 sesquiterpene hydrocarbons, and four sesquiterpene alcohols have been found. The structure of 1β,4αH,7αH,10βH-guaiane-5α,14-diol, one of the hydroboration-oxidation products of an unidentified sesquiterpene alcohol isolated from both oleoresins, has been determined by x-ray structural analysis.
