A new bis-iridoid glucoside, cocculoside (1), has been isolated, together with five known compounds from Strychnos cocculoides (Loganiaceae), collected in Tanzania. The structure of cocculoside (1) has been determined as an ester dimer of loganin and secologanin dimethyl acetal between C-7 and C-11
