【摘要】 为探讨龙牙草在石油醚中的溶解成分，利用索氏提取器获取了龙牙草石油醚提取物，并利用气相色谱-质谱(GC-MS)联用技术对其进行了分析.研究显示：龙牙草石油醚提取物的收率为3.20%;在龙牙草石油醚提取物的35个强色谱峰中共鉴定出27个成分，占石油醚提取物总含量的45.28%.27个成分中相对百分含量较高的成分依次为三环[3,5,7]癸烷-1-羧酸辛酯(6.42%)、胆酸乙酯(3.87%)、棕榈酸(3.67%)、(E)-3,7,11,15-四甲基十六醇-2-烯-1-醇(3.37%)、α-姜黄烯(2.93%)、绵马素(2.15%)等.该结果可为龙牙草的药理研究和开发利用提供参考.更多还原

【Abstract】 In order to further explore the components components of the whole Agrimonia pilosa Ledeb dissolved in the petroleum ether solvent, the components of Agrimonia pilosa Ledeb petroleum ether extract was obtained by Soxhlet extractor and analyzed by gas chromatography-mass spectrometry(GC-MS).The results showed that the extraction rate of the petroleum ether extract is 3.20%.27 components are identified from 35 chromatographic peaks of the separated Agrimonia pilosa Ledeb petroleum ether extract, accounting for 45.28% of the petroleum ether extract.The components with relatively high percentage content in the extract are tricyclic[3,5,7] decan-1-carboxylic acid octyl ester(6.42%), ethyl cholate(3.87%), palmitic acid(3.67%),(E)-3,7,11,15-tetramethylhexadecanol-2-en-1-ol(3.37%), α-curcumene(2.93%), and miasmasu(2.15%), etc.Thus, the references for the investigation, development and utilization of Agrimonia pilosa Ledeb herbal medicine will be provided.更多还原
