Cell viability and phytochemical profile of AP-SF. (A) The viability of RAW264.7 cells treated with either AP-SF or KG-SF in the absence of lipopolysaccharide was determined by MTT assay. (B) Phytochemical characteristics of ginsenosides in AP-SF or KG-SF were analyzed by HPLC. (C) The ginsenoside contents of AP-SF and KG-SF. AP, activator protein; HPLC, high performance liquid chromatography; KG, Korean ginseng; MTT, (3-4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide; SF, saponin fraction.
