Abstract
The n-BuOH fraction of the methanolic extract of T. cordifolia stems, has been acetylated and subjected to exhaustive chromatography (column , radial and preparative TLC). Two phytoecdysones. viz. ecdysterone 1 and makisterone A 2 have been isolated as their polyacetates. Their st ructures have been elucidated by extensive 1D and 2D NMR studies.
