C26H31NO17
formula, see observation
DEF

The natural glucoside which occurs in the indigo plant, by the decomposition of which indigo-blue is produced, which forms a light-brown syrup, of bitter taste, which gives rise to indoxyl on hydrolysis and is oxidized to indigo by air.

CONT

Natural indigo is derived from the hydrolyzation (splitting by water) of indican, a colorless glucoside (sugar derivative) obtained principally from the leaves of Indigofera tinctoria, I. suffruticosa, I. arrecta, and other indigo plants, as well as from the woad plant and the Asian herb Polygonum tinctorium. The splitting of indican produces glucose sugar and a yellow crystalline substance called indoxyl.

OBS

indol-3-yl ß-D-glucopyranoside: The letter "D" is a small capital; form recommended by the IUPAC (International Union of Pure and Applied Chemistry).
