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。

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 .
