目的研究习称为“三辛药”之一的藏药毕毕林精油化学成分及其相对含量。方法采用超临界CO2流体萃取法提取毕毕林精油,采用气相色谱-质谱联用方法分离鉴定精油化学成分并测定其相对含量。结果毕毕林超临界CO2流体萃取精油得率为9.7%,分离得到59个色谱峰,鉴定出52种成分,主要成分是胡椒碱(19.24%)、毕澄茄烯(10.62%)、4-硝基苯酯邻甲氧基苯甲酸(6.47%)、1-(1-氧代-11,14-二十碳三烯基)-吡咯烷(4.75%)、14(E)-十六碳烯醛(4.38%)、十五烷(4.35%)和反亚油酸甲酯(4.28%)等。结论二氧化碳超临界流体萃取精油是藏药毕毕林的药效组分之一,且是其辛味的主要物质基础。
Objective To study the chemical constituents and their relative contents of biodiesel in Tibetan medicine called “Sanxin Medicine”. Methods Bi bilin oil was extracted by supercritical CO2 fluid extraction method. The chemical constituents of essential oil were separated and identified by gas chromatography-mass spectrometry (GC-MS) and their relative contents were determined. Results The yield of essential oil extracted by supercritical carbon dioxide (CO2) fluid was 9.7%. Fifty-nine chromatographic peaks were obtained. Fifty-two components were identified. The main components were piperine (19.24%), beeswax (10.62% Phenyl ester o-methoxybenzoic acid (6.47%), 1- (1-oxo-11,14-icosadienyl) -pyrrolidine (4.75%), 14 (E) -hexadecenal (4.38%), pentadecane (4.35%) and methyl linolenate (4.28%). Conclusion The supercritical fluid extraction of carbon dioxide is one of the effective components of BiBin, and is the main material basis of its pungent taste.
