Two new acylated flavanone glycosides, (S)-eriodictyol 7-O-(6″-O-trans-p-coumaroyl)-β-D-glucopyranoside (1) and (S)-eriodictyol 7-O-(6″-O-galloyl)-β-D-glucopyranoside (2) were isolated from the leaves and branches of Phyllanthus emblica together with a new phenolic glycoside, 2-(2-methylbutyryl)phloroglucinol 1-O-(6″-O-β-D-apiofuranosyl)-β-D-glucopyranoside (3), as well as 22 known compounds. Their structures were determined by spectral and chemical methods.
