Inhibition of lipid-oxidation activities of ginseng extracts measured by β-carotene bleaching assay. (A) 2-year-old hydroponic ginseng (5 mg/mL) during fermentation; (B) 6-year-old soil-cultivated ginseng (5 mg/mL) during fermentation., non-fermented;
, 12 h fermented;
, 24 h fermented. The graphs are presented with triplicate experiments as mean value ± S.D. Different letters (a,b, 2 h; a*–d*, 4 h; a**–d**, 6 h.) on the error bars represent significant differences between same treated time (p < 0.05).
