Anthriscus sylvestris (L.) Hoffm. is a common perennial herb that is widely distributed in Europe, Korea, and New Zealand. The root of A. sylvestris has been used in Korean traditional medicine as an antitussive and cough remedy. However, the physiologically active function of A. sylvestris leaves is not yet known. In this study, we evaluated the anti-inflammatory effects, as well as the underlying molecular mechanisms of an aqueous extract of A. sylvestris leaves (AE-ASL) in vitro and in vivo. Our results indicated that pretreatment with AE-ASL significantly inhibited the lipopolysaccharide (LPS)-induced secretion of nitric oxide (NO) and prostaglandin E2 in RAW264.7 cells, without showing cytotoxicity. In addition, the LPS-induced mRNA and protein expression of inducible NO synthase, cyclooxygenase-2, and inflammatory mediators such as tumor necrosis factor alpha interleukin (IL)-1β, and IL-6 was attenuated by pretreatment with AE-ASL in a dose-dependent manner. Therefore, we investigated the activation of nuclear factor (NF)-κB, a transcription factor regulating the expression of inflammation-related genes. AE-ASL inhibited the nuclear translocation of the NF-κB p65 subunit by suppressing the phosphorylation and degradation of the inhibitor of NF-κB (IκBα). Further, AE-ASL inhibited the LPS-induced phosphorylation of mitogen-activated protein kinases (MAPKs) in RAW264.7 cells. Orally administered AE-ASL (50, 100, and 200?mg/kg of body weight [BW]) suppressed the development of carrageenan-induced rat paw edema by 15%, 31%, and 40%, respectively, after 4?h. Altogether, our results suggest that AE-ASL possesses anti-inflammatory activity, based on the suppression of NF-κB and MAPK pathways in vitro and inhibition of the carrageenan-induced paw edema in vivo.
