| Abstract: | Objective To study the optimum supercritical CO2 extraction technology of homoisoflavone from Radix Ophiopogonis.Methods The single-factor test and orthogonal tests were adopted to optimize the extraction process using the content of homoisoflavone as indicator.Results The optimal extraction conditions were the temperature at 55 ℃,the pressure at 20 MPa,the extraction time for 2 h and the entrainer volume for 2.0 mL/mg.Conclusion This technology is characterized by high extraction yield,simplicity and good reproducibility. |
