目的分离鉴定桉叶油中的生物活性成分。方法利用气相色谱-质谱联用仪GC-MS分离鉴定桉叶油生物化学成分。结果分离并鉴定α-蒎烯,β-蒎烯,水芹烯,P-伞花烯,桉叶油醇,松油烯,Alpha-松油醇,4-萜品醇等十余种化学成分。结论桉叶油的止血抗炎、止痛消肿及促渗促透作用等功效可能与其醇类及萜类成分有关。 Objective To isolate and identify bioactive components in eucalyptus oil. Methods The GC-MS was used to separate and identify the biochemical constituents of Eucalyptus oil. Results A dozen of chemical constituents such as α-pinene, β-pinene, phellandrene, p-cymene, eucalyptol, terpinene, Alpha-terpineol and 4-terpineol were isolated and identified . Conclusions Eucalyptus leaves oil may play an important role in hemostatic and anti-inflammatory, analgesic swelling, promoting penetration and penetration enhancement, and may be related to its alcohols and terpenoids.
