【摘要】 为了解广西高产脂马尾松(Pinus massoniana)松脂松节油含量及其化学成分特点,测定松脂松节油含量,利用气相色谱-质谱联用技术(GC-MS)和气相色谱法(GC)分析松节油的化学成分,并与普通马尾松松脂中的松节油进行比较。结果表明,高产脂马尾松的松节油含量与普通马尾松差异不显著,但高产脂马尾松的松节油含量变异系数大于普通马尾松。高产脂马尾松松节油的7个主要化学成分中,除月桂烯的变异系数低于普通马尾松外,其他6个化学成分的变异系数均大于普通马尾松。相关分析结果表明,高产脂马尾松松节油含量与长叶烯呈极显著正相关,与石竹烯呈极显著负相关。松节油中的一些成分在不同单株间差异极显著,可进行特定化学成分的优良单株筛选,可为松脂加工产业提供更优质的原料选择。更多还原

【Abstract】 In order to study turpentine content and chemical components in oleoresin from high-oleoresin-yield Pinus massoniana in Guangxi, turpentine content was determined and chemical components of turpentine were analyzed by GC-MS and GC, which were compared with nomal P. massoniana. Results showed that there was no significant difference in turpentine content between high-oleoresin-yield P. massoniana and nomal P. massoniana, but coefficient of variation of turpentine content in high-oleoresin-yield P. massoniana was larger than that of nomal P. massoniana. In seven chemical components of turpentine in high-oleoresin-yield P. massoniana, coefficient of variations of six components were greater than those of nomal P. massoniana except for myrcene. Correlation results showed that turpentine content in high-oleoresin-yield P. massoniana had extremely significantly positive correlation with longifolene and extremely significantly negative correlation with caryophyllene. There were extremely significant differences in some components of turpentine among different individual plants. Excellent individual plants with specific chemical components could be screened, which would provide higher quality of raw materials for oleoresin processing industry.更多还原
