Methyl esters derived from diazomethane esterification the components of Pinus Elliottii Engelm.resin were analyzed in detail by means of GLC and GC/MS.Abietate 8, isopimarate 5, Δ8, 9isopimarate 6, and neo alietate 9 were found to be the main components, and seven components dehydroabietate 7, pimarate 2, sandaracopimarate 3, sandaracopimaral 1, 15-hydroxyabietate 10, and 7 α-and 7 β-hydroxyhydroabietate 11, 7-oxodehydroabietate 12, as minor components. Analysis was also made of methyl esters derived from diazomethane esterification the components of South Part of American and Chinese gum resins. The components of Pinus Elliottii Engelm. resin were quite similar to those of American gum resin.
