A new acylated flavonoid glycoside, named euryanoside (1), has been isolated together with known compounds, halleridone (4) and cornoside (5), from male flowers of Eurya japonica THUNB. (Theaceae). The structure of 1 has been established to be apigenin 5-O-α-L-rhamnopyranosyl-(1→2)-(6"-O-acetyl)-β-D-glucopyranoside, based on lines of chemical and spectral evidence. In addition, the first identifications of 4 and 5 from the Theaceae are also reported.
