| 摘 要： | 目的：探索金银花的新型提取工艺.方法：采用紫外分光光度法测定绿原酸含量,比较水提法与液-液双相连续萃取法对绿原酸提取率的差别.结果：水提法与液-液双相连续萃取法对绿原酸提取率的差异具有显著性,液-液双相连续萃取法所得浸膏率低、绿原酸占浸膏比率高.结论：液-液双相连续萃取法所提绿原酸虽在含量上低于普通水提取,但其纯度高,杂质含量少,可作为一种有效的金银花中绿原酸的提取分离方法. |
| 关 键 词： | 金银花 绿原酸 液-液双相连续萃取法 |

| Abstract: | Objective：To study a new exlraction method for chlorogenie acid in Flos Lonicerae. Methods： Uhraviolet spectrophotometry method was used to determine the content of chlorogenic acid. The abstraction rate of chlorogenie acid by water extraction was compared to that of liquid-liquid continuous extraction method. Results ：There was a significant difference between the two methods on chlorogenic acid extraction rate. Liquid-liquid continuous extraction method has low extract rate, and chlorogenie acid accounts for high proportion of the concrete. Conclusion： The liquid-liquid continuous extraction method is a new and high efficiency separation method. |
