其中微波10min，晒干处理过的样品，无论是挥发油含量还是总木脂素的含量均较其它加工方法的高，且工序简单，比较有推广价值。

Methods The orthogonal design was used to study three factors including the amount of adding water,macerating time,distillating time.

采用了正交设计法考察土荆芥、水团花水蒸汽蒸馏加水量、浸泡时间及提取时间3个因素，以挥发油提取量为考核指标；滴制成的胶丸采用气相层析法进行主成分比较分析。

Results: The results showed that the socking time has significant influence on the extraction of volatile oil (P.05) and the velocity of percolation has less influence on it.

结果：结果表明，在考查范围内，渗漉前浸泡的时间对挥发油的提取的影响最大(P.05)，渗漉速度的影响最小。

ResultsThe optimum inclusion condition was that volatile oil∶β-CD in proportion as 1∶8 was mixed, and triturated 2 hours,30℃.

结果实验结果显示，最佳包合条件为挥发油∶β-CD=1∶8，搅拌时间2 h，包合温度为30℃。

Influence of supersonic treatment on extraction of almond essential oil was studied.
