摘　　要：以茶树花为原料,采用超声有溶剂法提取茶树花精油。以茶树花精油得率为指标,在单因素试验的基础上通过响应面法优化提取工艺,并与索氏抽提法对比分析茶树花精油得率及其挥发性成分。结果表明:超声有机溶剂法提取茶树花精油的最佳工艺为超声功率240W、超声时间50min、石油醚添加量160mL、浸泡时间6h,在此条件下,茶树花精油得率为3.34%,而索氏抽提法的茶树花精油得率为1.59%。成分分析显示,在超声有溶剂法提取的茶树花精油中共检出23种挥发性成分,而在索氏抽提法提取的茶树花精油中只检出18种挥发性成分。Using tea flowers as raw materials,tea flower essential oil was extracted by ultrasonic organic solvent method.Taking the yield of tea flower essential oil as the indicator,the extraction process was optimized by response surface method based on single factor experiment,and the yield and volatile com-ponents of tea flower essential oil were compared and analyzed with Soxhlet extraction method.The re-sults showed that the optimal ultrasonic organic solvent extraction process for tea flower essential oil was ultrasonic power 240 W,ultrasonic time 50 min,petroleum etheraddition 160 mL,and soaking time 6 h.Under these conditions,the yield of tea flower essential oil was 3.34%,while the yield of tea flower es-sential oil extracted by Soxhlet extraction method was 1.59%.Component analysis showed that 23 vola-tile components were detected in the tea flower essential oil extracted by ultrasonic organic solvent meth-od,while only 18 volatile components were detected in the tea flower essential oil extracted by Soxhlet extraction method.
