目的采用超临界CO2技术提取罗勒子中的生物活性成分,并确定其组成。方法用气相色谱-质谱法对罗勒子超临界CO2萃取物进行化学成分的分析。结果 GC-MS分析萃取物得到63个峰,鉴定出其中的58种化合物,占所有化合物总量的99.23%。最为丰富的为:亚油酸(68.70%);三十酸甲酯(5.22%);棕榈酸(3.69%);穿贝海绵甾醇(3.45%);E-角鲨烯(2.55%)。此外,还检测出许多萜类化合物,相对质量分数约1%。结论罗勒子富含多种抗肿瘤、降血糖、抗衰老、降血压等的活性成分,有较高的开发利用价值。
Objective To extract the bioactive components of basil by supercritical CO2 and determine its composition. Methods Gas chromatography-mass spectrometry (GC-MS) was used to analyze the chemical constituents of the supercritical carbon dioxide extract of basil. Results Sixty-three peaks were obtained by GC-MS analysis, of which 58 compounds were identified, accounting for 99.23% of the total compounds. The most abundant are: linoleic acid (68.70%); methyl tristearate (5.22%); palmitic acid (3.69%); mepiquat sterol (3.45%); and E-squalene (2.55%). In addition, many terpenoids were also detected with a relative mass fraction of about 1%. Conclusion The basil is rich in a variety of anti-tumor, hypoglycemic, anti-aging, antihypertensive and other active ingredients, have a higher value of development and utilization.
