Himalaflavones F and G, two new flavonoids from the roots of <i>Oxybaphus himalaicus</i> Edgew with anti-inflammatory activity

Himalaflavones F (<b>1</b>) and G (<b>2</b>), two new flavonoids, along with eight known ones (<b>3-10</b>)were isolated from the roots of <i>Oxybaphus himalaicus</i> Edgew. The chemical structures of these compounds were elucidated by 1D/2D NMR, UV and HR-ESI-ME data. Meanwhile, the anti-inflammatory activities of all isolates were test by using Griess method. Among them 10 μM of compounds <b>1</b>, <b>2</b>, <b>8</b> and <b>10</b> could decrease the NO release against LPS-induced RAW264.7 macrophages. The results suggested that these compounds have the potential to be developed as anti-inflammatory drugs.
