| 摘要: |
| 为比较极小种群野生植物资源冷杉(Abies ziyuanensis)和元宝山冷杉(A. yuanbaoshanensis)针叶精油化学组成成分,该文利用水蒸气蒸馏法提取资源冷杉和元宝山冷杉针叶精油,采用GC-MS分析确定其精油化学物质成分,并基于峰面积归一化法计算各组分相对含量。结果表明:分别从资源冷杉和元宝山冷杉针叶精油中鉴定出化学物质21种和22种,其中15种为两种冷杉共有成分; 烯烃类物质是资源冷杉和元宝山冷杉针叶精油中含量最高的组分,占比分别为95.94%和95.02%。两种冷杉共有成分中β-蒎烯、1-石竹烯、莰烯、α-石竹烯和异松油烯具有较大开发利用价值; 非共有成分方面,资源冷杉中α-松油醇和α-蒎烯以及元宝山冷杉中α-依兰油烯和叶醇均具有较大开发利用价值。以上结果为开发利用两种冷杉针叶精油提供了理论依据。 |

| Abstract: |
| In order to compare the chemical constituents of essential oil of needles from Abies ziyuanensis and A. yuanbaoshanensis, essential oil of needles were extracted by steam distillation, and were determined by GC-MS analysis. The relative content of each component was calculated based on the peak area normalization method. The results were as follows: 21 and 22 kinds of chemical substances were identified in the essential oil of needles from A. ziyuanensis and A. yuanbaoshanensis, respectively, among which 15 kinds of chemical substances were the common components of these two firs; The olefinic substances were the highest content in essential oil of needles from both A. ziyuanensis and A. yuanbaoshanensis, the proportion were 95.94% and 95.02%, respectively. Among the common components of these two firs, β-Pinene, l-Caryophyllene, Camphene, α-Caryophyllene and Terpinolene have high development and utilization values; in terms of non-common components, α-Terpineol and α-Pinene in A. ziyuanensis, α-Muurolene and leaf alcohol in A. yuanbaoshanensis both had great development and utilization values. This study provides a theoretical basis for the development and utilization of these two firs. |
