Optical morphological transformation (a) and cell viability (b) of on lipopolysaccharide (LPS) (1 µg/mL)-induced Raw 264.7 cells treated with the solvent fractions (HEX—hexane, DICHO—dichloromethane, EA—ethyl acetate and BUT—butanol) of Geranium koreanum (DGK) (100 and 200 µg/mL) for 24 h. The cell viability was determined using a cytotoxicity assay kit and showed no cytotoxicity. The morphology was visualized by a light microscope at 200× magnitude. Data are means ± standard deviation (SD); * p < 0.05 compared with compared with LPS control cells.
