Abstract: The preparation processes of turpentine from masson pine, slash pine, and simao pine were studied comparatively with solvent and steam distillation methods. The characteristic properties of three kinds of turpentine prepared by steam distillation method had all met the super grade requirements of China national standard——GB/T 12901-2006 "Gum turpentine". The analytical results of GC and GC-MS showed that the chemical characteristic compositions of three kinds of turpentine are separately α-pinene, β-pinene, linmonene, β-phyllendrene, longifolene and β-carryophylene, etc. The obvious difference would be related to the relative content ratios of α-pinene and β-pinene, which are 8.5 (masson pine turpentine), 2.0 (slash pine turpentine), and 4.0 (Simao pine turpentine), respectively. The characteristic parameter difference of relative content ratio of α-pinene to β-pinene would be used as an important evidence for the identification of pine species.
Key words: masson pine (Pinus massoniana Lamb.), slash pine (Pinus elliottii Engelm.), Simao pine (Pinus kesiya var. langbiangensis (A. Chev) Gaussen), turpentine oil, reference materials
