A new C-methylated flavone glycoside, 5,7-dihydroxy-3-methoxy-6-C-methylflavone 8,4'-di-O-β-D-glucopyranoside (1), was isolated from the twigs and leaves of Picea neoveitchii Mast, together with eight known compounds, 5,7,8,4'-tetrahydroxy-3-methoxy

The electrochemical properties of an iridium(IV)-substituted Dawson type heteropolytungstate anion have been studied in organic and aqueous solutions using cyclic voltammetry. In acetonitrile solution, this species exhibits four-step one-electron red
