Abstract：Clove esential oil isa volatile natural aromaticsubstance extracted from clove bud， which has non-toxic， anti-inflammatory，anti-cancer，bactericidalandantioxidantproperties.Theexperimentusedultrasonicassistedsteam distilation to extract essential oilfrom lilacflower buds.Fourfactors，including solid-liquidratio，ultrasonic power， particle size，and time，were investigated.The optimalconditions areobtained through response surface optimization： solid-liquid ratio of 1：15， power of $3 0 0 ～ ＼mathrm { ＼textW }$ ，130 mesh， 90min ，and extraction rate of 13.45% . The obtained essential oil has good antioxidantactivity，with an inhibitionrate of 80% on superoxide radicals at3 mg/mL.

Key Words： clove essential oil; ultrasonic asistance; response surface method optimization; antioxidant activity

丁香花蕾精油富含丁香酚（ 46%～87% ），具广谱抗菌、镇痛及自由基清除活性， 3mg/mL 时对超氧阴离子的抑制率可达 80% ，表明天然产物替代合成抗氧化剂具有明确的应用前景{。（剩余4542字）
