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.

Key words: rosin of Pinus massoniana Lamb, reference materials, certification report
