| 摘 要： | 苦参是一种用于治疗多种疾病的传统中药材,苦参碱类生物碱是其主要的活性物质,既有药用价值又有杀虫效果.作者利用超临界二氧化碳(SC-CO2)去除苦参中的脂溶性物质,建立了节能环保的后续苦参碱提取工艺.检测了脂溶性物质(R1)和苦参总碱(R2)的得率;评价了超临界流体萃取(SFE)过程的参数,如压力、温度、时间对R1和R2的影响,并与直接溶剂萃取进行对照.结果显示,使用本法所得苦参总碱的平均产率比直接用溶剂萃取高72%,在压力为12～18MPa、温度60～75℃、萃取时间2h下苦参碱得率较高. |
| 关 键 词： | 超临界流体萃取 苦参碱 脂溶性物质 |

| Abstract: | Sophora flavescens Ait.is a traditional Chinese medicine that has been used for the treatment of various diseases for centuries.Matrine-type alkaloids are the primary active substances that can be used in medicine and pesticide.In this paper,supercritical carbon dioxide(SC-CO2) was used to remove lipid-soluble substances so that a cleaner sample of S.flavescens was available for extraction of matrine-type alkaloids.The recovery of lipid-soluble substances(R1) and the recovery of matrine-type alkaloids(R2) w... |
| Keywords: | supercritical fluid extraction matrine-type alkaloids lipid-soluble substances |
