Ethnopharmacological relevance:: Saussureae Involucratae Herba (SIH), known as snow lotus in Uyghur and/or Chinese medicines, is generated from the dried aerial part of Saussurea involucrata (Kar. et Kir.) Sch.-Bip. (Asteraceae). The major pharmaceutical value of SIH has been recorded in China Pharmacopoeia, i.e. to balance the immune system, and thus SIH is commonly used for rheumatoid arthritis treatment. Nevertheless, the detailed mechanism of SIH in immune function is still unresolved. Aim of the study: Here, we employed macrophage RAW 264.7 cell as a model to demonstrate the signaling pathways, triggered by SIH, in regulating the LPS-induced inflammation. Methods: The application of SIH methanolic extract suppressed the expression of cytokines, a hallmark of chronic inflammation, in lipopolysaccharide (LPS)-stimulated cultures. Results: The anti-inflammatory functions of SIH were shown to be triggered via NF-kappa B/PI3K/MAPK signaling pathways by revealing the specific biomarkers, i.e. translocation activities of NF-kappa B and phosphorylations of Erk1/2, JNK and Akt. Conclusion: The aforementioned results showed the underlying action mechanism of SIH in chronic inflammation mitigation, and which might shed light on clinical applications of SIH in traditional Chinese and/or Uyghur medicines.
