چکیده
OBJECTIVE This study assessed anti-inflammatory and antioxidant activities of E. foetidum leaf extract on LPS-activated murine macrophages. METHODS RAW264.7 cells were pretreated with or without E. foetidum extract for 1 h prior to incubation with LPS for 24 h. Anti-inflammatory activity was evaluated with reference to iNOS, COX-2, TNF-α and IL-6 gene expression. In addition, NO and intracellular ROS generation were determined by Griess method and fluorescence intensity and activation of MAPKs and IκB by Western blotting. RESULTS Prior treatment with E. foetidum leaf extract inhibited elevation of IL-6, TNF-α, iNOS and COX-2, together with their cognate mRNAs in a dose-dependent manner. NO and intracellular ROS contents were similarly reduced. These effects were due to inhibition of LPS-induced phosphorylation of JNK and p38 as well as IκB. E. foetidum ethanol extract was shown to contain lutein, β-carotenes, chlorogenic acid, kaempferol and caffeic acid, compounds known to exert these bioactive properties. CONCLUSIONS E. foetidum leaf extract possesses suppressive effects against pro-inflammatory mediators. Thus, E. foetidum has a high potential to be used as a food supplement to reduce risk of cancer associated with inflammation.

متن کاملAnti-Inflammatory Activity of Bioaccessible Fraction from Eryngium foetidum Leaves
Eryngium foetidum (EF) has long been used as a medicinal plant and culinary spice in tropical regions. Phytochemicals in its leaves have been proposed to be responsible for the anti-inflammatory and antioxidant activities. The present study used in vitro digestion coupled with Caco-2 cells to assess such activities. Caco-2 cells were incubated with aqueous fraction from simulated digestion (bio...

Eryngium foetidum L. is an important plant cultivated as leafy vegetable and for its essential oil, which is of high economical value in international market. Multiple shoots (17.8) were obtained through direct regeneration from leaf excised from field grown plants of E. foetidum and cultured on Linsmaier and Skoog’s Basal Medium (LSBM) fortified with BAP (1.5 mgl) and PVP (250 mgl). After subc...

High frequency somatic embryogenesis and plant regeneration was achieved on calli developed from internodal and flower buds of E. foetidum. The explants were cultured on Murashige and Skoog medium supplemented with different concentrations and combinations of BA and IAA. The nodal explants produced multiple adventitious shoots while the internodal and flower buds induced callus, from which mult...
