Antioxidant neolignan and phenolic glucosides from the fruit of Euterpe oleracea

Three new glucosides, namely, (–)-7R8S-7′,8′-dihydroxy-dihydrodehydroconiferyl alcohol-9-O-β-d-glucopyranoside (1), (+)-7S8R-7′,8′-dihydroxy-dihydrodehydroconiferyl alcohol-9-O-β-d-glucopyranoside (2) and 4-hydroxy-2-methoxyphenyl 1-O-[6-(hydrogen 3-hydroxy-3-methylpentanedioate)]-β-d-glucopyranoside (3), along with 6 known compounds were isolated from the fruit of Euterpe oleracea Mart. Their structures were elucidated based on spectroscopic analyses including NMR, HR-ESI-MS and CD. All the isolated compounds demonstrated significant antioxidant activity and 2 displayed moderate cytotoxicity against HL-60 cells.
