A potassium sodium, C8H6NO4SK, found in sweat and urine and created because of the conversion of tryptophan to indole by abdominal micro-organisms.
A glucoside, C14H17NO6, occurring in indigo-plant and used as a source for indigo dye.
A glucoside gotten from woad alongside flowers, the foundation of all-natural indigo.
An indigo-forming material within urine and other animal liquids, and convertible into purple and blue indigo (urrhodin and uroglaucin); an indoxyl sulphate of potash.
A glucoside (C14H17NO6) obtained from woad (indigo plant, Isatis Tinctoria) along with other plants (see indigo), as a yellow or light brown sirup. When purified it is obtained as spear-shaped crystals. It's a nauseous sour flavor. By the action of acids, enzymes, etc., it breaks down into sugar and indigo. It is the way to obtain normal indigo. Chemically it will be the 3-glucoside of indole, H-indol-3-yl-β-D-glucopyranoside.
An indigo-forming substance, present urine, also pet fluids, and convertible into purple and blue indigo (urrhodin and uroglaucin). Chemically, it really is indoxyl sulphate of potash, C8H6NSO4K, and it is produced by the indol formed inside alimentary channel. Called also uroxanthin.
The all-natural glucoside (C26H31NO17) because of the decomposition that indigo blue is created from the different types of indigo-producing plants.
The alkali salt of indoxyl-sulphuric acid, C8H6NSO4H. It happens in urine. See the following phrase.
