Figure 6: Effect of GA, 4-OMGA, GAE, and PG on LPS stimulated PGE2 production in RAW 264.7 cells. PGE2 was measured in the culture medium of the cells with pretreated with different concentration of compounds and then stimulated with LPS, Indometahcine use as positive control. GA compared with LPS *P > 0.05, GAE compared with LPS **P > 0.01. GA: Gallic acid; 4-OMGA: 4-O methyl gallic acid; GAE: Gallic acid ethyl ester; PG: Pyrogallol; LPS: Lipopolysaccharide; PGE2: Prostaglandin E2

PGE<sub>2</sub> was measured in the culture medium of the cells with pretreated with different concentration of compounds and then stimulated with LPS, Indometahcine use as positive control. GA compared with LPS *<i>P</i> > 0.05, GAE compared with LPS **<i>P</i> > 0.01.
