| 520 | 3 | _aArtemisia anomala S. Moore exerts many pharmacological activities, including the removing of the blood stasis, relieving of the fever and analgesia, reducing the swelling and dampness. In this study, the extraction technology, chemical compositions and anti-inflammatory effect in vitro and mechanism of total flavonoids extract from Artemisia anomala S. Moore were studied. The optimal yield rate of total flavonoids extract was optimized by single factor experiments and response surface method, and the chemical constituents were analyzed by UPLC-QTOF-MS method; and the anti-inflammatory activity of the extract was evaluated with lipopolysaccharide induced RAW 264.7 cells. The highest extraction rate was 2.02 percent under these conditions of the concentration of ethanol 50 percent, the ultrasonic extraction time 30 min, and the ratio of solvent volume to material weight 20:1 (ml/g). In addition, the main components of total flavonoid extract were preliminarily identified and deduced based on mass spectrometry information and relevant literatures, and its stronger anti-inflammatory activity was demonstrated by reducing the phagocytosis, the content of nitric oxide and the level of related cytokines (tumor necrosis factor-?, interleukin-10, interleukin-6). Furthermore, it was further revealed that the anti-inflammatory effect of the extract was closely connected with the activation of TLR4-MyD88-NF-?B signalling pathway. This study indicated that the total flavonoids extract from Artemisia anomala S. Moore may be a better candidate anti-inflammatory natural medicine. | |
