  Indican \In"di*can\, n. [See {Indigo}.]
     [1913 Webster]
     1. (Chem.) A glucoside ({C14H17NO6}) obtained from woad
        (indigo plant, {Isatis Tinctoria}) and other plants (see
        {indigo}), as a yellow or light brown sirup. When purified
        it is obtained as spear-shaped crystals. It has a nauseous


        bitter taste. By the action of acids, enzymes, etc., it
        breaks down into sugar and indigo. It is the source of
        natural indigo. Chemically it is the 3-glucoside of
        indole, H-indol-3-yl-[beta]-D-glucopyranoside.

     2. (Physiol. Chem.) An indigo-forming substance, found in
        urine, and other animal fluids, and convertible into red
        and blue indigo (urrhodin and uroglaucin). Chemically, it
        is indoxyl sulphate of potash, {C8H6NSO4K}, and is derived
        from the indol formed in the alimentary canal. Called also
        {uroxanthin}.
