摘要

目的:研究了委陵菜黄酮类化合物的提取与纯化工艺条件。方法:采用正交设计研究了4因素4水平的委陵菜黄酮提取条件

并从最适样品浓度、上样量、乙醇洗脱液浓度、乙醇洗脱用量等方面对AB-8型大孔树脂纯化委陵菜黄酮的工艺条件进行了研究。结果:最适提取条件为:在70℃条件下

乙醇浓度为40%

固液比为1g∶100mL

提取3次的效果最佳。最适纯化条件为:当黄酮液浓度为0.4mg·mL-1时

吸附速率最佳;洗脱液为70%的乙醇;乙醇的洗脱用量达到4倍床体积数时

解吸率较高。其粗黄酮粉的黄酮含量为17.98%

经AB-8型大孔吸附树脂纯化后的委陵菜精黄酮粉中黄酮含量约达48.36%。

Abstract

Objective:To study on the technology of extraction and purification of flavonoids from Potentilla chinensis.Methods: The optimal extracting conditions of flavonoids from Potentilla chinensis were screened with a 4-factor-four-level orthogonal test and AB-8 macroporous resin was selected for purification conditions.Results:The best extracting conditions were as follows.The sauple was extracted at 70℃ with 40% ethanol(the solid-liquid ratio 1 g∶100 mL)

for 3 times The concentration of the sample solution suitable for purification was 0.4 mg·mL-1.The portion eluted with 70% ethanol and 4 times volume of the resins was collected.The flavonoid content of crude flavonoid powder was 17.98%.After being purified with AB-8 macroporous resin

the flavonoid content could reach to 48.36%.
