Armeniacae semen is the seed of Prunus armeniaca L. var. ansu MAXIM which is classified into Rosaceae. In traditional oriental medicine, Armeniacae semen has been used for the treatment of pain and inflammatory diseases. In this study, the effect of Armeniacae semen extract on lipopolysaccharide-induced inflammation was investigated using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay, reverse transcription-polymerase chain reaction (RT-PCR), Western blot, prostaglandin E-2 immunoassay, and nitric oxide detection on mouse BV2 microglial cells. In the present results, Armeniacae semen extract suppressed prostaglandin E-2 synthesis and nitric oxide production by inhibiting the lipopolysaccharide-stimulated enhancement of cyclooxygenase-2 and inducible nitric oxide synthase mRNA expression in BV2 cells. These results show that Armeniacae semen exerts anti-inflammatory and analgesic effects probably by suppression of cyclooxygenase-2 and inducible nitric oxide synthase expressions.
