Abstract
Chemical analysis of the aerial parts of Artemisia argyi H. Lév. & Vaniot led to the isolation of 6 lignans, including a new lignan glycoside, artemisiaside A, using various chromatographic techniques. Detailed spectroscopic (including 1D, 2D- nuclear magnetic resonance) and high resolution mass spectroscopy procedures, and electronic circular dichroism were used to ascertain the structural orientations of these compounds. The anti-inflammatory activities of compounds 1 to 6 were evaluated by measuring their inhibitory effects on lipopolysaccharide (LPS) -induced nitric oxide (NO) production in RAW264.7 LPS-activated macrophages. At 50 μM, compound 1 showed moderate anti-inflammatory activity with an inhibition rate of 61.2%.
