| 摘要: |
| 用正交法获得灵香草净油最佳超临界萃取条件为压力为15 MPa,温度为35℃,时间为1.5h,CO2流量为30m3/h。放大试验结果表明,平均收率可达1.5%,变异系数为0.72%。用GC-MS技术分析净油的化学成分,发现用超临界CO2萃取的净油的化学成分与以往的研究有一定差异。 |

| Abstract: |
| The favor conditions obtained by orthogonal comparison for extracting the extrait of Lysimachia foenum-graecum by the supercritical carbon dioxide are as follows:pressure 15 Pa,temperature 35℃,extracting time 1.5 h,CO2 flux 30 m3/h.It is obtained by amplifying test that the extrait recovery is up to 1.5% with variation coefficient of 0.72%.The chemical components of the extrait are analyzed and reveal difference to some extent from the results of the previous researches. |
