摘要
目的:分析抱茎龙船花脂溶性化学成分。方法:抱茎龙船花枝叶的甲醇提取物加水后,用乙酸乙酯萃取,乙酸乙酯部分进行硅胶柱层析,石油醚洗脱部分得其脂溶性成分,然后通过气相色谱—质谱(GC-MS)联用技术,对其中的化学成分进行分析鉴定。结果:通过计算机检索,鉴定了其中的46个化合物,占挥发油总量的96.03%。主要成分为棕榈酸甲酯(19.07%)、邻苯二甲酸二丁酯(14.95%)、棕榈酸(9.62%)、棕榈酸丁酯(7.63%)、油酸乙酯(7.15%)、硬脂酸甲酯(5.66%)、油酸甲酯(5.64%)、亚麻酸甲酯(3.85%)、棕榈酸异戊酯(2.99%)、油酸(2.92%)、月桂酸甲酯(2.10%)、二十酸甲酯(2.03%)等。结论:抱茎龙船花脂溶性化学成分主要为脂肪酸及酯类、芳香酸酯、烷烃类及芳香类化合物。
Objective： The purpose of this research was to analyze the liposoluble constituents of Iroxa amplexicaulis.Methods： The plant material was powdered and extracted with MeOH for eight times.The extract was concentrated,added with water and then partitioned with EtOAc.The EtOAc part was chromatographed directly on a silica gel column and eluted with a gradient of petroleum ether and EtOAc（1：0 to 0：1）.The petroleum ether elution was concentrated and then analyzed by gas chromatography-mass spectrometry.Results： 46 components were identified from the liposoluble fraction,representing 96.03% of the total constituents.The major components were methyl hexadecanoate（19.07%）,dibutyl phthalate（14.95%）,palmitic acid（9.62%）,butyl palmitate（7.63%）,ethyl oleate（7.15%）,methyl stearate（5.66%）,methyl oleate（5.64%）,methyl linoleate（3.85%）,isoamyl palmitate（2.99%）,oleic acid（2.92%）,methyl laurate（2.10%） and methyl arachidate（2.03%）.Conclusion： The major compounds from the liposoluble fraction of Iroxa.amplexicaulis were fatty acids and their esters,ester of aromatic acid,alkanes and aromaticas.
