摘 要：洋甘菊精油因具有抗炎、解痉、消毒、利胆作用而被广泛应用。本论文以广西产洋甘菊为原料，采用水蒸气蒸馏法提取洋甘菊精油，考察了料液比、提取时间、浸泡时间、超声波辅助等因素，确定洋甘菊精油提取最佳工艺条件为:液料比为 1：12，提取时间为 5h，浸泡时间为2h，其中用超声波处理30min，提取率1.12%；还对有机溶剂萃取法、超临界 CO2流体萃取工艺进行了初步探索。

The Research on Extraction of Chamomile Essential Oil
Abstract: As its anti-inflammatory,antispasmodic,disinfectant and choleretic effect, chamomile has been widely used. In the research, the materials of chamomile was planted in Guangxi, steam distillation were applied to extract the chamomile essential oil ,the main conclusions as follows:
In the single-factor test, the influence of ratio of material and liquid,extraction time, soaking time, ultrasonic wave time, was studied, and obtain the chamomile essential oil by the method of steam distill, the optimum extracting condition was obtained:the ratio of material to water is 1:12(g/ml), extracting for 5h, soaking for 2h,and dealing with ultrasonic for 30min before, the yield of essential oil was 1.12%. Although, organic solvent extraction, supercritical CO2 fluid extraction were explored.
