摘要
目的:研究海南砂仁的脂溶性成分。方法:利用溶剂分步萃取,得到各萃取部位;采用气相色谱-质谱(GC-MS)联用技术对其石油醚部位的成分进行测定,并与标准图谱对照,确定化合物成分,经色谱峰面积归一化法确定各成分的相对百分含量。结果:从海南砂仁石油醚萃取部位中共分离出76个组分,鉴定了其中的56种成分,所鉴定的成分占总脂溶性成分的68.81%,其中相对质量分数较高的成分有对苯二酚(7.74%)、Z,E-2,13-十八碳二烯-1-醇(6.86%)、E,E-2,13-十八碳二烯-1-醇(5.44%)、4-十一烷基苯酚(3.71%)、(Z)-9-十八碳烯醛(3.65%)、顺式-异油酸(3.39%)及(E,E)-大牻牛儿-3,7(11),9-三烯-6-酮(3.05%)等。结论:本研究首次对海南砂仁的石油醚部位的化学成分进行了分析,该研究为海南砂仁的进一步开发和利用提供了基础研究数据。
Objective:To investigate the chemical constituents in the lipid soluble composition from the fruits of Amomum longiligulare.Methods:The petroleum ether fraction was extracted by solvent step by step and its chemical constituents were separated,determined and identified by gas chromatography-mass spectrometry combined with computer retrieval in compound databases.The relative percentage content of each compound was calculated by peak area normalization method.Results:76 compounds were separated and 56 of them were identified,which covered 68.81% of the total lipid soluble composition.The major constituents with higher relative content were hydroquinone(7.74%),Z,E-2,13-octadecadien-1-ol(6.86%),E,E-2,13-octadecadien-1-ol(5.44%),4-undecylphenol(3.71%),(Z)-9-octadecenal(3.65%),cis-vaccenic acid(3.39%)and(E,E)-germacra-3,7(11),9-trien-6-one(3.05%).Conclusion:Chemical constituents of the petroleum ether fraction from the fruits of A.longiligulare were analyzed for the first time.The present study provides a chemical basis for A.longiligulare .
