菊米超临界CO2萃取物的气相色谱-质谱分析及其抑菌活性
用气相色谱-质谱（gas chromatography—mass spectrometry，GC-MS）对通过超临界C02萃取的菊米精油成分进行分析，并通过测定其抑菌圈直径判断其抑菌活性．结果表明：经GC—MS分析在菊米精油中共鉴定出28个相似度在70％以上的成分，以萜类及其衍生物为主，其中萜类主要为单萜和倍半萜，其衍生物主要为醇；菊米精油对金黄色葡萄球菌和大肠杆菌具有一定的抑菌效果，其最小抑菌质量浓度（minimum inhibitory concentration，MIC）为1．6mg／mL，显示出良好的抑菌活性．...

Jumi essential oil has numerous efficacies and applications in the field of pharmacy and cosmetic industry, therefore developing effective oil extracting method which can keep both biological activity and fragrance is of considerable significance. At present, steam distillation has been reported as essential oil extract method, but this method can not keep the unique fragrance of Jumi due to the decomposition of fragrant component at high temperature. However, the supercritical fluid of COz （SFE-COz） is a low temperature processing technique and can fully keep the uni |
