지역별 백리향 지상부 잎의 phenols 성분의 효과적인 추출을 알아보기 위해 추출용매를 달리하여 추출하고, GC-MS로 분석한 결과thymol과 carvacrol을 포함한 phenol함량이 methanol 추출 시 울릉도, 제주 중간산지, 경기도, 제주도 고산지, 강원도 종이 각각 92.21, 84.92, 77.43, 74.16, 73.51%로 추출되었으며, ethanol 추출 시 전체 추출 성분 중 강원도, 제주도 중간산종, 경기도, 울릉도, 제주고산종이 각각 93.64, 93.62, 90.74, 89.52, 72.65% 순으로 나타났다. Hexane을 용매로 추출하였을 때에는 강원도와 울릉도 서식의 백리향은 거의 100, 95.71%의 phenol만 추출되었다. Thyme leaves of aerial part in 5 domestic species was extracted by several solvens, and chemical composition of extracts was analyzed by GC-MS to determine the effective solvent for phenol compound extracts. Total phenol contents containing thymol and carvacrol according to methanol extracts of Ulleung island, Jeju middle mountain, Kyeonggido, Jeju alpine species, and Gangwondo were 92.21, 84.92, 77.43, 74.16, and 73.51%, while them of ethanol extracts of Gangwondo, Jeju middle mountain, Kyeonggido, Ulleung island, and Jeju alpine species were in the order of and their contents were 93.64, 93.62, 90.74, 89.52, and 72.65%, separately. Hexane extracts of Gangwondo and Ulleung island thyme were almost composed by phenol contents containing thymol for 100 and 95.71%.
