Abstract:
OBJECTIVETo optimize extracting parameters of flavonoids from Humulus lupulus.
METHODBased on the single factors test on ethanol concentration, material and solvent ratio, extracting temperature and extracting time, orthogonal test was performed and the best combination was confirmed.
RESULTWith the optimized technology, the maximal extracting amount of flavonoids from H. lupulus was 78 mg x g(-1).
CONCLUSIONThe optimal techniques obtained are 45% ethanol extracting at 60 degrees C with material and solvent ratio 1:25 for 90 min.
