中文摘要:

将巴西绿蜂胶原胶制备出乙醇提取液及蜂胶渣,采用超声波辅助萃取对巴西绿蜂胶原胶、乙醇提取液及醇提后蜂胶渣中的挥发性成分进行提取,GC-MS分析,比较其在化学组成及含量上的差异。分析鉴定出蜂胶原胶挥发性成分中主要活性物质14种,主要是芳香酸及烯萜类化合物;蜂胶乙醇提取液及蜂胶渣挥发性成分中主要活性物质分别为14种和11种,主要为烯萜类化合物和有机酸酯类,蜂胶乙醇提取物中主要挥发性物质还含有烷烃类化合物。结果表明,蜂胶原胶、蜂胶乙醇提取液及蜂胶渣中的挥发性成分的化学组成有一定的相同性也存在一定的差异,但其含量明显不同并且存在一定的转化关系。

英文摘要:

In this study,ethanol extract and dregs were prepared by ethanol extracting of Brazilian green propolis.Then ultrasonic assistant extraction technology was used to obtain volatile components from raw material,PEES and DPEES.The chemical components were separated and identified by gas chromatography-mass spectrometry(GC-MS).14 active ingredients were identified from Brazilian propolis volatile components and the major components were aromatic compound and ene terpenoids,14 and 11 active ingredients were identified from PEES and DPEES volatile components,the major components were ene terpenoids and organic acid esters,but the main volatile substances in the PEES also contains alkanes.The results revealed that there are some same volatile components as well as some different ones among raw material PEES and DPEES,but their contents is obviously different,meanwhile some active ingredients can transformed between each other.
