摘要：

[Objective] To study the volatile component in Melissa officinalis L. leaves and to compare the volatile components extracted from M. officinalis leaves by two extraction methods.[Method] The volatile components from M. officinalis extracted by using simultaneous distillation extraction and ultrasonic-assisted extraction were identified by GC-TOFMS and computer spectrum search.The effects of different extraction methods on volatile components were also compared. [Result] 93 components were separated from M. officinalis leaves by using simultaneous distillation extraction and 41 of them were identified, accounting for about 89.79% of the total content. The most abundant constituent was gerznial (24.54%). 67 components were separated by using simultaneous distillation extraction and 31 of them were identified, accounting for about 92.26% of the total content. The most abundant constituent was palmitic acid (30.80%). [Conclusion] There were significant differences in the volatile components and its relative contents in Melissa officinalis L. leaves by different extraction methods.
