摘要
介绍了使用气相色谱法分析马尾松松香。通过检验马尾松松香中异海松酸含量大 小可以确定是否混杂湿地松松香。马尾松松香和湿地松松香中异海松酸含量分别为<2%和 >15%。当马尾松松香中异海松酸含量超过2%时将表明它混杂湿地松松香。
A GC method for examinating rosin was presented. The different contents of isopimafic 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. massoniana rosin is judged to be blended with some P. elliottii rosin when its content of isopimaric acid is 〉 2 %.
