Abstract: Rosin samples were prepared from pure Pinus massoniana Lamb.oleoresin,pure P.elliottii Engelm.oleoresin and pure P.kesiya var.langbinanensis（A.Chev.） Gaussen oleoresin.The main resin acid contents of the rosins were analyzed by GC quantitative analysis using DB-5 capillary column.Rosin type can be determined and distinguished from the content of isopimaric acid and the quantity ratio of pimaric acid/isopimaric acid.The content of isopimaric acid and the quantity ratio of pimaric acid/isopimaric ... More
