  1. Quercitron

    Quercitron is a yellow natural dye obtained from the bark of the Eastern Black Oak, a forest tree indigenous in North America. The name is a shortened form of quercicitron, from Latin quercus, oak, and citron, lemon, and was invented by Dr Edward Bancroft, who by act of parliament in 1785 was granted special privileges in regard to the importation and use of the substance. The dyestuff is prepared by grinding the bark in mills after it has been freed from its black epidermal layer, and sifting the product to separate the fibrous matter, the fine yellow powder which remains forming the quercitron of commerce. The ruddy-orange decoction of quercitron contains quercitannic acid, whence its use in tanning, and an active dyeing principle, quercitrin, C21H20O12. The latter substance is a glycoside, and in aqueous solution under the influence of mineral acids it yields quercetin, C15H10O7, which is precipitated, and the methyl-pentose rhamnose. Quercetin is a crystalline powder of a brilliant citron yellow color, entirely insoluble in cold water and dissolving only sparingly in hot water, but quite soluble in alcohol. Either by itself or in some form of its glucoside quercitrin, quercetin is found in several vegetable substances, among others in cutch, in Persian berries, buckwheat leaves, Zante fustic wood, and in rose petals.
