This paper discusses the colorimetric determination of Sanguis Draconis flavones. Comparison on the difference of absorption curve using the characteristics that Sanguis Draconis flavones can produce color with various chromogenic reagents.  The results showed that the common AlCl3£¬NaNO2 - Al (NO3) 3 - NaOH Colorimetries for determination of total flavonoids were not suitable for Sanguis Draconis flavones.
