[Study on totai flavonoids of Epimedium assisted with soybean polysaccharide spray-drying powder].

In order to evaluate the characteristics of the spray drying of total flavonoids of Epimedium extracts assisted with soybean polysaccharide, a certain percentage of soybean polysaccharide or polyvidone were added to the total flavonoids of Epimedium extract to conduct the spray drying. The effect of soybean polysaccharides against the wall sticking effect of the spray drying was detected, as well as the powder property of total flavonoids of Epimedium spray drying powder and the dissolution in vitro behavior of the effective component. Compared with the total flavonoids of Epimedium spray drying powder, soybean polysaccharide revealed a significant anti-wall sticking effect. The spray drying power which had no notable change in the grain size made a increase in the fluidity, improvement in the moisture absorption and remarkable rise in the dissolution in vitro behavior. It was worth further studying the application of soybean polysaccharide in spray drying power of traditional Chinese medicine.
