Abstract
AbstractFrom the ethyl acetate extract of the stem bark of Phyllanthus emblica, a mixture of triterpene glycosides (1) and six compounds (2‐7) were isolated. The structure of these compounds were established as 3‐O‐α‐L‐arabinopyranosyloleanolic acid (1a), 3‐O‐α‐L‐arabinopyranosylursolic acid (1b), 16‐dehydropregnenolone (2), periplogenin (3), betulin (4), phyllanthol (5), gallic acid (6) and methyl gallate (7) by 1D, 2D NMR spectroscopies, and high resolution ESI‐MS analysis, as well as comparison with those reported in the literature. The compounds (1a), (1b), (2) and (3) were found for the first time from this genus.
