Effect of CH₂Cl₂ fractions from A. koreanum fruit waste on nitric oxide (a) and PGE₂ (b) production in RAW 264.7 cells. Effects of CH₂Cl₂ fractions from A. koreanum fruit waste on nitric oxide production in RAW 264.7 cells were determined from the 24-hr culture of cells stimulated with LPS (1 μg/mL) in the presence of CH₂Cl₂ fractions. Nitric oxide production was determined by the Griess reagent method. PGE₂ released into the culture medium was assayed by ELISA. The data represent the mean ± SD of triplicate experiments. Values are the mean ± SEM of triplicate experiments. *P < .05; **P < .01.
