The results showed that SFE-CO_2 was the ideal method to extract volatile oils from lotus leaves. GC-MS was applied to isolate and analyze the components of extracted volatile oils. 76 components were detected, among which SD and SE detected 23 components respectively, while SFE-CO_2 detected 52 components. The main ingredients were terpenes, alcohols, esters, ketones and alkyls, etc.
