灵香草

用超临界CO2萃取技术（SFE-CO2），对灵香草（Lysimachiafoenum-graecumHance）进行了萃取，得到灵香草萃取物。

The extract from Lysimachia foenum-graecum Hance was obtained by supercritical carbon dioxide extraction ( SFE-CO_2 ) technique .

结果：超临界CO2萃取灵香草提取物得率1.5%，鉴定出27个化学成分，溶剂法得率1.2%，鉴定出20个化学成分；

Result : yield of extract of Lysimachia foenum-graecum Hance by supercritical CO 2 extraction is 1.5 % , 27 chemical components were identified , yield of solvent extraction is 1.2 % , and 20 chemical components were identified ;

超临界CO2法得到的灵香草萃取物收率为4.5%，高于水蒸气法的收率，且香气纯正。

The result showed that the yield of the SFE-CO_2 product was 4.5 % , much higher than that of the steam distillation product , and its aroma was pure .
