title: A new iridoid diglucoside from Harpagophytum procumbens.
abstract: A new iridoid diglucoside has been isolated from an aqueous extract of Harpagophytum procumbens secondary roots, together with six known compounds. Its structure has been assigned as 6'-O-glucopyranosyl-8-O-trans-coumaroylharpagide by spectroscopic means.
