Chemical study of the stem bark of Phyllanthus emblica (Phyllanthaceae)

From 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.
