RESUMEN
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 (6S,9R)-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 IC50 values ranging from 8.5 to 26.9 µM.
