摘　　要：用纯马尾松松脂、纯湿地松松脂、纯思茅松松脂制得松香样品；应用DB-5毛细管柱对松香样品中主要的树脂酸含量进行了气相色谱定量分析；通过测定松香样品中异海松酸GC含量和海松酸／异海松酸GC含量的比值，可以确定并鉴别松香所属种类。纯马尾松、湿地松、思茅松松香的异海松酸GC含量及海松酸／异海松酸GC含量的比值分别是：〈2％为8．58；4％～5％为1．24；≥14％为0．24。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 acid are 〈 2 % , 8.58 ; 4 % -5 % , 1.24 ; ≥14 % , 0.24 for pure P. massonlana Lamb. rosin, pure P. elliottil Engelm, rosin and pure P. kesiya var. langbinanensis rosin respectively
