Abstract: Objective To optimize the extraction technology of flos Puerariae lobata isoflavone. Methods The flos Puerariae lobata isoflavone was distilled by ethanol circumfluence. Total flavonoids, tectoridin and tectorigenin extracted from Puerariae using the UV and HPLC spectromertry methods were taken as evaluation indexes. Extraction technology was optimized with L9(34) orthogonal test on the base of single observation of ethanol concentration, solvent dosage and distilling time. Results The best extraction technology of flos Puerariae lobata isoflavone was: to add 12 times the amount of 70% ethanol for 90 minutes for the first time, and 10 times the amount of 70% ethanol for 60 minutes for the second time. Conclusion The optimized extraction process of flos Puerariae lobata isoflavone is reasonable and feasible, and it can offer reference to actual production.
