Open publisher page 1 citations

Abstract

A GC method for examinating rosin was presented.The different contents of isopimaric acid in rosins of Pinus massoniana and P.elliottii,which are 2 % and 15 % respectively,can be utilized to judge whether a rosin is a blended one.A P.masscniana rosin is judged to be blended with some P.elliottii rosin when its content of isopimarie acid is 2 %.
