Abstract:
:Methanolic extract of Miliusa balansae Finet et Gagnep exerts an anti-inflammatory effect via inhibition of nitric oxide (NO) production in lipopolysaccharide (LPS)-stimulated murine RAW 264.7 macrophage cells. Three new megastigmane glycosides, milbasides A-C (1-3), together with fifteen known compounds (4-18), were isolated from the active fraction. Their chemical structures were elucidated using extensive spectroscopic analyses, including 1D and 2D NMR, HR ESI MS, and CD analysis, as well as comparison with previously reported data. Compounds 1-3, 11 and 14 (20.0 μM) showed potent inhibitory activities with inhibition values of 98.5 ± 1.6%, 90.9 ± 7.8%, 84.8 ± 3.5%, 91.5 ± 8.7%, and 91.8 ± 2.7%, respectively. Our results suggest that megastigmane glycosides from M. balansae leaves may be used to treat inflammatory diseases.
