Five compounds were isolated from the peels of chufa (Eleocharis dulcis (Burm.f.) Trin. ex Hensch., Cyperaceae). The chemical structures were determined by various spectroscopic analysis methods, including 1D and 2D NMR, and by comparison with literature data. All compounds were isolated for the first time from the peels of chufa. Compounds orcinol glucoside, leonuriside A, 2-hydroxymethyl-6-(5-hydroxy-2-methyl-phenoxy-methyl)-tetra-hydro-pyran-3,4,5-triol, and 1,4-dihydroxy-3-methoxy-phenyl-4-O-β-d-glucopyranoside showed good acrylamide formation activity, and acrylamide inhibition rates were 30.24, 32.81, 30.53, and 28.18%, respectively.
