摘 要:目的:研究香姜颗粒挥发油超临界CO2流体萃取的最佳工艺.方法:以蒿本内酯含量和收油率为指标,95%乙醇为夹带剂,用正交试验法进行优选;用高效液相色谱法对蒿本内酯的含量进行测定,色谱柱为Phenomenex Luna C18(250mm×4.6mm,5μm),流动相为甲醇-0.5%醋酸(30∶70),检测波长为280nm.结果:香姜颗粒挥发油萃取的最佳工艺条件为萃取温度50℃,萃取压力45MPa,萃取时间3h,95%乙醇作为夹带剂.蒿本内酯在5.1~25.5 μg·mL-1浓度范围内线性关系良好(r=0.999 8).结论:该工艺制备简便,操作可行,可为大生产提供理论依据.OBJECTIVE: To study the optimum supercritical- fluid extraction technique for Xiangjiang Granula essential oil. METHODS: The orthogonal test was adopted to optimize the extraction process using the content of Ligustilide and the yield rate of essential oil as indicators, and 95% ethanol as co-solvents. The content of Ligustilide was determined by HPLC, using Phenomenex Luna C18(250nm × 4.6nm, 5μm) as column and methanol - 0.5% glacial acetic acid(30 : 70) as mobile phase, with the detection wavelength set at 280 nm. RESULTS: The optimal extraction conditions were: temperature at 50℃, pressure at 45MPa, extraction time for 3h, and 95% ethanol as co-solvents.The Ligustilide had a good linearty relationship between 5.1-25.5μg · mL^-1(r = 0.999 8) .CONCLUSIONS: This technique is easy, convenient and workable, and can provide theoretical support for production.
