[Study on extraction total flavonoids in Epimedium koreanum using high pressure technology].

ABSTRACT

OBJECTIVE: To provide a modern method for extraction and separation total flavonoids in Epimedium koreanum. METHOD: 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. RESULT: The extraction efficiency is 9.67% and taking 5 min by high pressure method, using reflux, is 6.14% and 4 h respectively. CONCLUSION: The method of high pressure is high efficiency and saving time, which have extensive application in the extraction of Traditional Chinese Medicine.
