Objective: Purify the total flavonoids from Hedyotis diffusa. with macroporous resin and establish optimum process for separating and purifying total flavonoids from H.diffusa. Method: The optimal techniques of separation and purification of flavonoid were obtained by static adsorption and elution tests
and the separation techniques were evaluated by measuring the concentration of total flavonoids from H.diffusa with ultraviolet spectrophotometer. Result : The HPD-826 macroporous resin gave the best effect of separation with the sampling rate 2 BV ·h-1
concentration 1.0 g ·L-1
pH 5 respectively
and the concentration of elution was 80% alcohol
eluting velocity 2 BV ·h-1
with pH 7. Conclusion : HPD-826 resin could be applied to purify total flavonoids from H.diffusa.
