采用溶剂提取法、硅胶柱层析分离,获得海南核果木果实脂溶性提取物Ⅰ和Ⅱ,结合气相色谱-质谱联用对其化学成分进行分离、鉴定及分析。结果发现,海南核果木果实脂溶性提取物Ⅰ中主要为邻苯二甲酸二(2-乙基己基)酯(64.2%)和烷烃类(23.6%);从脂溶性提取物Ⅱ中鉴定出19种成分,主要为烯烃类(1.4%)、烷烃类(22.9%)、酯类(68.0%)以及植物醇(2.8%)等,酯类为饱和脂肪酸酯(35.8%),主要为软脂酸甲酯(29.0%)和十八碳酸甲酯(6.8%),不饱和脂肪酸酯(18.6%),主要为11,14-十八碳二烯酸甲酯(10.1%)和6,11-二十碳二烯酸甲酯(8.5%),另外,还含有邻苯二甲酸二(2-乙基己基)酯(13.6%)。
Solvent extraction and silica gel column chromatography were used to obtain the liposoluble extracts Ⅰ and Ⅱ of Hainan korean fruits. The chemical constituents were separated, identified and analyzed by gas chromatography-mass spectrometry. The results showed that di-2-ethylhexyl phthalate (64.2%) and alkanes (23.6%) were the main components of the fat-soluble extract Ⅰ of Hainan drupe, and 19 The main components are olefins (1.4%), alkanes (22.9%), esters (68.0%) and phytols (2.8%). The esters are saturated fatty acid esters (35.8% (29.0%) and methyl stearate (6.8%), unsaturated fatty acid esters (18.6%), mainly methyl 11,14-octadecadienoate (10.1%) and 6,11 -dicosadienoate (8.5%), in addition to di-2-ethylhexyl phthalate (13.6%).
