临夏种植和野生艾叶精油的制备及挥发性成分分析

    Preparation and Volatile Component Analysis of Essential Oil from Planted and Wild Artemisia argyi Leaves in Linxia

    • 摘要: 为了促进临夏艾叶产业发展,通过水蒸气蒸馏法提取种植和野生艾叶精油,测定艾叶精油含量,运用气质联用仪(GC-MS)进一步分析艾叶精油挥发性成分,为临夏艾叶资源合理利用提供科学依据。结果表明:临夏种植艾叶精油提取率为0.55%,GC-MS分离出71种成分,其中34种成分得到鉴定,鉴定成分相对含量为83.25%,含量较高的是龙脑(14.73%)、桉叶油醇(14.42%)、α-侧柏酮(10.78%);临夏野生艾叶精油提取率为0.45%,GC-MS分离出84种成分,其中42种成分得到鉴定,鉴定成分相对含量为73.55%,含量较高的是桉叶油醇(13.08%)、樟脑(9.24%)、α-侧柏酮(8.51%)。研究显示与其他产地艾叶相比,临夏种植艾叶精油含有较高的龙脑,是资源优势;临夏野生艾叶无明显优势。

       

      Abstract: In order to promote the development of Artemisia argyi industry in Linxia, the essential oil from the cultivated and wild Artemisia argyi was extracted by steam distillation, and the essential oil content of Artemisia argyi was determined. Then, the volatile components of essential oil from Artemisia argyi were further analyzed by GC-MS, which provided a scientific basis for the rational utilization of Artemisia argyi resources in Linxia. The results showed that: the extraction rate of essential oil from wild Artemisia argyi in Linxia was 0.45%. A total of 84 components were separated by GC-MS, of which 42 components were identified with a relative content of 73.55%, and the contents of eudesmol (13.08%), camphor (9.24%) and α-thujone (8.51%) were higher. The research has shown that compared with Artemisia argyi from other producing areas, the essential oil of Artemisia argyi grown in Linxia contained higher levels of borneol, which was a resource advantage. However, there was no obvious advantage in wild Artemisia argyi leaves in Linxia.
