摘　　要：目的研究苗药大果姜子果实挥发油的化学成分并初步探讨其抗心血管活性成分。方法采用了超临界CO_2萃取方法从大果木姜子果实中提取挥发油,运用气相色谱-质谱-计算机联用技术对其化学成分进行鉴定,用面积归一化法测定各化合物在果实挥发油中的相对百分含量。结果共分离鉴定了58个化学成分,占总挥发油成分的51.95%。结论主要成分是古巴烯7.73%、n-癸酸4.68%、桉树脑3.24%、斯巴醇3.20%、β-人参萜烯3.11%,为进一步开发大果木姜子提供科学依据。Objective To analyze the chemical constituents of essential oils from fruits of cinnamomum migao H. W. Li. and discuss the active constituents to cure cardiovascular disease Methods The es- sential oils were extracted by supercritical CO2 extraction, and then the constituents were separated and identified by GC-MS. The relative contents of essential oils were calculated with area normalization in this article. Results Fifty eight compounds were identified representing 51.95% of the essential oils. Con- clusion The principal chemical constituents of essential oils are eopaene, n-decanoic acid, eucalyptol, spathulenol, ^-panasinsene. The scientific foundation were provided for further development of the plant to be utilized as a kind of new midicine.
