Two new compounds that were identified as mucic acid 2,5-di-O-gallate (1) and mucic acid 2,5-di-O-gallate 1,4-lactone (2) and 14 known compounds, including for the first time in a plant 3,4,6-tri-O-galloyl-β-D-glucose, were identified by a phytochemical investigation of Phyllanthus emblica (Phyllanthaceae) fruit. Compounds 1 and 2 exhibited pronounced antioxidant activity.
