Using single factor test and orthogonal test, the optimal processes of extracting total flavonoids from Clerodendrum Chinense (Lour) Merr were established by the absorption of total flavonoids. The optimum conditions for extracting the total flavonoids assisted were as follow:extraction temperature 80℃, extraction time 90 min, 80%ethanol and ratio of solid to liquid 1∶25. The mass fraction of total flavonoids extracted was up to 2.68%. It was suggested that the optimum extraction process was simple, stable, efficient and feasible.
