Effects of Steaming Treatment on the Effective Components and Efficacy in Vitro of Ginseng Flowers.

The effective composition, antioxidant, enzyme inhibition and bile binding ability of Ginseng flowers after different steaming times were studied. The results showed that different steaming times affected the effective components of ginseng flower, the content of polysaccharide and total saponins reached the highest when steaming for 5 times, the total flavonoids and phenol increased with the times of steaming. Steaming treatment significantly induced the ability of antioxidant and inhibition of α-amylase; but reduced the inhibition of α-glucosidase and cholate binding ability. Steaming treatment improved the effective content of ginseng flower and facilitate the production of low polar saponins; steaming changes the composition of ginsenoside.
