[Study on extraction total flavonoids in Epimedium koreanum using high pressure technology].
OBJECTIVE
To provide a modern method for extraction and separation total flavonoids in Epimedium koreanum.


METHODS
Using high pressure technology extracts total flavonoids in E. koreanum, and comparing with counter-current extraction with reflux. The total flavonoids contents is determined by UV-VIS.


RESULTS
The extraction efficiency is 9.67% and taking 5 min by high pressure method, using reflux, is 6.14% and 4 h respectively.


CONCLUSIONS
The method of high pressure is high efficiency and saving time, which have extensive application in the extraction of Traditional Chinese Medicine.
