Total extract of SFE-CO_2 were 4.86 times of the essential oil extracted by SDE, main active extracted constituents were 1.36% high than SDE. The chemical constituents of SFE-CO_2 were also analyzed by GC-MS. 57 constituents were identified, 29 constituents of them were first discovered. 24 constituents were discovered in two extract. Fingerprint is a good technology to elevate the quality of herb medicine. The main active fraction can be extracted by SDE and SFE, Fingerprint was studied respective, chromatographic parameter was acquired. 22 peaks were assigned common peaks in the spectrum of essential oil, 17 peaks were assigned to common peaks in the spectrum of SFE extract.
