dc.description.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-arabinopyranosylursoIic 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.vi_VN
