ABSTRACT
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, 5? m) 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. 5? g? mL- 1( r=0. 999 8) .CONCLUSIONS:
This technique is easy, convenient and workable, and can provide theoretical support for production.
