本文主要研究内容
作者毛运芝,冯璐璐,冉慧,刘世尧（2019）在《缙云山5种乡土楠木资源叶片精油挥发性成分GC-MS鉴定与组成差异分析》一文中研究指出：【目的】对缙云山5种野生乡土楠木植物资源叶片精油进行提取和成分鉴定,分析5种楠木植物精油挥发性成分组成差异研究和亲缘关系,为野生乡土楠木类资源的开发应用与分类提供基础数据。【方法】按照代表性原则于7月初在叶片年光合效率最高时采样,采用水蒸气蒸馏法进行叶片精油提取,气相色谱-质谱联用技术（GC-MS）分离,计算机自动检索辅助人工解析,对缙云山5种乡土楠木资源叶片精油组分进行鉴定与差异分析,用SPSS 19.0软件对挥发性组分进行主成分分析和聚类分析。【结果】缙云山5种乡土野生楠木植物资源叶片精油提取率分别为0.313 5%、0.003 6%、0.096 4%、0.075 3%和0.070 7%,白楠出油率最高,雅安琼楠次之,峨眉楠最低,白楠是峨眉楠的87倍。通过GC-MS鉴定,从5种乡土野生楠木植物资源叶片精油中共鉴定出挥发性组分187种,其中白楠78种,主要为喇叭烯(2.911 0μg·g-1)、δ-卡迪烯(2.043 5μg·g-1)和α-杜松醇(1.634 9μg·g-1);峨眉楠62种,主要为正十六烷酸(0.230 4μg·g-1)、亚油酸(0.076 3μg·g-1)和植醇(0.058 6μg·g-1);雅安琼楠79种,主要为α-蒎烯(1.687 1μg·g-1)、δ-卡迪烯(1.316 0μg·g-1)和乙酸龙脑酯(1.249 2μg·g-1);贵州琼楠79种,主要为α-蒎烯(1.607 5μg·g-1)、δ-卡迪烯(1.448 7μg·g-1)和古巴烯(1.393 9μg·g-1);利川润楠54种,主要为13-烯十四醛(6.495 7μg·g-1)、十四醛(2.375 4μg·g-1)和癸醛(0.934 7μg·g-1)。从成分种类上看,缙云山5种乡土野生楠木植物资源叶片精油挥发性组分以烯烃和醇类为主,此外还有酯类、烷烃类、醛类、萘类、酮类、有机酸类、苯类和其他多种化合物类型;但共有性成分少,仅有7种。通过主成分分析和聚类分析,5种乡土野生楠木植物资源可明显分为3类,雅安琼楠和贵州琼楠植物叶片挥发性成分组成相似,聚为一类;峨眉楠和利川润楠聚为一类;而白楠挥发性组分明显不同于其他几种,单独聚为一类。【结论】缙云山5种乡土楠木植物资源叶片精油挥发性组分均以烯烃和醇类为主,但成分含量差异较大,叶片精油化学分类研究结果与传统形态学的亲缘关系具有一定差异。
