Abstract
Abstract The results of GC-MS, Py-GC-MS and spectroscopic (solid state 13 C NMR) studies of the structure and composition of two resinites, viz. Highgate Copalite and Glessite , which have been previously described as “fossil elemi” are described. GC-MS analyses of Highgate Copalite establish that this resinite is composed of a simple mixture of diterpenoid resin acids and n -alkyl materials. Based on comparison of these data with similar data obtained by analysis of modern rosin, it is concluded that this resinite is most probably derived from the resin of an undetermined species of pine. In order to accomodate resinites of this general character, it is propose...
