[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.
[1913 Webster +PJC]

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.
