Effect of crude extract and solvent fractions from A. koreanum fruit waste on nitric oxide (a) and PGE₂ (b) production in RAW 264.7 cells. Effects of crude extract and solvent fractions from A. koreanum fruit waste on the 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 A. koreanum . 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.
