摘 要：
[目的]通过对广西不同企业的马尾松松香样品进行分析,找出广西马尾松松香各树脂酸的范围。[方法]应用QF-1毛细管柱对广西不同企业的马尾松松香样品甲酯化后进行气相色谱分析。[结果]根据测定结果,广西松香树脂酸含量范围:海松酸7.28%～9.38%,山达海松酸0.91%～3.59%,异海松酸0.27%～1.97%,长叶松酸12.67%～36.55%,脱氢枞酸2.02%～5.25%,枞酸28.69%～63.06%,新枞酸8.72%～22.94%。松香中海松酸6%～10%,山达海松酸1.0%～2.5%,异海松酸小于2.0%可判定为马尾松松香。[结论]松香产品质量与生产过程中松脂树脂酸热异构有关,可通过树脂酸的含量范围来判定马尾松松香。

摘 要：
[Objective] The rosin samples of Pinus massoniana that from different enterprises in Guangxi were analyzed,range of rosin acid of Pinus massoniana was given.[Method] The rosin samples after methyl ester of Pinus massoniana that from different enterprises in Guangxi were analyzed by GC analysis using QF-1capillary column.[Result] The results showed the resin acid content ranges of rosin in Guangxi: pimaric acid 7.28%-9.38%,sandaracopimaric acid 0.91%-3.59%,isopimaric acid 0.27%-1.97%,palustric acid 12.67%-36.55%,dehydroabietic acid 2.02%-5.25%,abietic acid 28.69%-63.06%,neoabietic acid 8.72%-22.94%.Range of pimaric acid at 6%-10%,sandaracopimaric acid at 1.0%-2.5%,isopimaric acid lower than 2.0% in rosin was regards for rosin of Pinus massoniana.[Conclusion] Quality of rosin related to rosin acid isomerism in rosin processing,rosin of Pinus massoniana was judged by ranges of rosin acid.
