Abstract: Vegetable tannins, used by the tanning industry, are considered to be eco-friendly because of their natural tanning agents. They are composed of polyphenols and are divided into hydrolysable and condensed tannins. Hydrolysable tannins are glucose polyesters classified into gallic or ellagic tannins. Condensed tannins, however, consist of catechin monomers, known as flavonoids. The native sources of plant extracts for tanning hides, the tanning potential of the barks of Black Jurema (Mimosa tenuiflora [Willd.] Poir.) and Red Angico (Anadenanthera macrocarpa [Benth.] Brenan.) trees were evaluated; these species were collected from the semi-arid region of Morada Nova, in the state of Ceará, and from the cerrado biome region of Campo Grande, state of Mato Grosso do Sul (Brazil), respectively. These extracts were characterized and classified as condensed tannins. When compared to the black wattle (Acacia mearnsii De Wild), these tannins presented a lower extraction yield as well as lower light fastness. The tanning methodology used in the Morada Nova sheep hides was the same as that used in the evaluation of black wattle. The leather was not re-tanned |
