摘要
目的:分析和比较不同部位及不同采收期蕲艾精油含量与化学成分的差异,为蕲艾的综合开发与合理利用提供科学依据。方法:采用水蒸气蒸馏法(SD)提取蕲艾叶、蕲艾花、蕲艾茎及5月至10月不同采收期的蕲艾叶精油,结合气相色谱-质谱联用技术(GC-MS)分析其化学组成。结果:蕲艾叶精油含量显著高于蕲艾花与蕲艾茎,且蕲艾叶精油化学成分种类与相对含量均高于蕲艾花与蕲艾茎。不同采收期蕲艾精油提取率存在较大差异,其中6月蕲艾精油含量最高。经SD-GC-MS分析表明,不同采收期蕲艾精油均检测出含量较高的桉油精、樟脑、冰片和α-蒎烯等。结论:蕲艾叶为蕲艾的最佳药用部位,且6月为蕲艾的最佳采收期。
Objective： To compare and analyze the difference in content and chemical components of essential oil from Artemisia argyi,providing scientific basis for the comprehensive development and utilization of A. argyi. Method： The essential oil from A. argyi leaves,flowers and stems as well as from different growing periods from May to October was extracted by steam distillation（ SD） and chemical components were analyzed by gas chromatography-mass spectrometry technique（ GC-MS）. Result： The essential oil content from A. argyi leaves was significantly higher than those from flowers and stems,and the types and relative contents of the essential oil from A. argyi leaves were higher than those from flowers and stems. There was great difference in essential oil content from A. argyi among different harvesting periods,and the content was highest in June. SD-GC-MS analysis showed that the essential oil from A. argyi during different harvest periods had high content of eucalyptol,alcanfor,orneol and α-pinene. Conclusion： Leaves are the best medicinal parts of A. argyi,and June is the optimum harvest time for A. argyi.
