YE Bo-hui

Abstract

This paper provides method of certification report of reference materials of P.massoniana Lamb.rosin for GC analysis.The property and uncertainty value on the content(GC%) of seven resin acids from reference materials was made certain by six laboratories united-certification.They are pimaric acid: 8.2683±0.3203,sandaracopimaric acid: 1.7433±0.3199,isopimaric acid: 0.7652±0.3118,palustric acid: 30.8201±1.3668,dehydroabietic acid: 3.2731±0.8693,abietic acid: 34.9275±1.2664,neoabietic acid: 18.7469±1.8494.
