Total polyphenol, flavonoid contents, and cellular antioxidant activity of ginseng extracts. (A) Change in total polyphenol and flavonoid contents of ginseng extracts after steam processing. (B) ABTS and (C) CAA assays of ginseng extracts. Significant differences between the means of various treatment groups are represented by different letters. A p value of less than 0.05 was considered statistically significant. Values are expressed as means ± standard error of mean; n = 3. ABTS, 2,2′-azinobis-(3-ethylbenzothiazoline-6-sulfonic acid); BGE, black ginseng extract; CAA, cellular antioxidant activity; GAE, gallic acid equivalent; RGE, red ginseng extract; RE, rutin equivalent; TFC, total flavonoid content; TPC, total polyphenols; WGE, white ginseng extract.
