The studies was proceeded on the the supercritical CO2 extraction technique of rotenone from Tephrosia vogelii. The extraction influences of technology conditions were systematically groped, The research results were listed as follows:1 The analysis method applied in this paper has been proved to be suitable to technology research of the studies on the SC-CO: extraction technique of rotenone from Tephrosia vogelii. 3 indexes, extraction ratio of rotenone. extraction ratio of total compounds and rotenone content percent in total compounds weight, were carried out with HPLC quantitatively determination combined with the sample weight loss after extraction. With these 3 indexes. The extraction influences of technology conditions were evaluated by synthesis. Then the best technology conditions were ascertained for different extraction aims.2 The pretreatment of rough material should be needed before extraction. Comminuting the material to 0.28mm size is most fit to SC-CO: extraction.3 Firstly static extracting 20 min then turn to dynamic doing is the better extraction mode than other ones.4 The orthogonal experiment was conduct with 3 factors and 5 levers.
本论文通过对非洲山毛豆SC-CO_2萃取中影响萃取效果的工艺条件的研究,初步得出如下结果:(1)本论文中所采用的萃取效果评价方法适宜于非洲山毛豆中鱼藤酮的超临界流体萃取技术研究,该方法具体为:HPLC定量分析非洲山毛豆SC-CO_2萃取物中的鱼藤酮含量,再结合萃取前后处理样品的重量损失,得出鱼藤酮萃取率、萃取所得粗物质萃取率和粗物质中鱼藤酮含量三个参数,以此三个指标综合评价萃取条件对萃取效果的影响;(2)通过对原料粒度对萃取效果影响的研究,结果表明SC-CO_2萃取非洲山毛豆复叶中的鱼藤酮,原料粉碎成30目粒度叶粉时萃取效果较好;(3)通过对萃取方式与萃取效果之间关系的研究,结果表明SC-CO_2萃取非洲山毛豆中鱼藤酮应采用先静态后动态的萃取方式,静态萃取时间为20min;(4)通过温度、压力和CO_2流量三因素五水平的正交试验,结果表明温度是最主要的影响因素,压力因素对鱼藤酮萃取率的影响程度高于CO_2流量,而对于粗物质萃取率和粗物质中鱼藤酮含量CO_2流量因素高于压力。
