Tirucallane Glycoside from the Leaves of Antidesma bunius and Inhibitory NO Production in BV2 Cells and RAW264.7 Macrophages
Description:
<jats:p> One new tirucallane- type triterpene glycoside, antidesoside (1), along with two biflavones, podocarpusflavone A (2) and amentoflavone (3) and two megastigmane glycosides, byzantionoside B (4), and (6 S,9 R)-roseoside (5) were isolated from the methanol extract of Antidesma bunius leaves. Their structures were determined by spectroscopic methods and in comparison with the published data. Compounds 1 - 3 were found to show strong inhibitory effect of NO production in BV2 cells and RAW264.7 macrophages LPS-stimulated, with IC<jats:sub>50</jats:sub> values ranging from 8.5 to 26.9 μM. </jats:p>
