摘    要:为从6种不同采集期的艾叶中提取正构烷烃,并比较其成分和含量,寻找艾叶的最佳采收期,采用梯度溶剂萃取法提取了艾叶正构烷烃,用气相色谱-质谱法分析了其化学成分.结果表明:6种不同采集期艾叶的正构烷烃成分中含量最高的是C31,不同正构烷烃含量呈明显的奇偶优势分布,3号和4号长链正构烷烃含量较高.故6月上旬为艾叶的最佳采收期.

关 键 词:艾叶  正构烷烃  气相色谱-质谱联用

Abstract:To compare and analyze the chemical constituents and the yield of n-alkanes extracted from Artemisia argyi gathered from six different growing periods , and find the best harvest time for Artemisia argyi.The n-alkanes were extracted by gradient solvent and the chemical constituents were analyzed by GC-MS.The results indicated that the component with highest percentage is C 31 , and the n-alkane content showed an odd-even predominance distribution .Sample 3# and 4#offered higher yields of long-chain alkanes , corresponding to the best harvest season of early June .
Keywords:Folium Artemisia argyi  n-alkanes  GC-MS
