Abstract
V teoretičnem delu je prikazana sestava hidrolizirajočih in kondenzirajočih taninov. Pri prvih je osnova galna kislina, pri drugih predvsem katehin. Obe osnovni komponenti se povezujeta v komplicirane spojine, ki so kemijsko vezanena sladkorje, kar njihovo zgradbo še dodatno zaplete. Poudarek je na preučevanju tanina treh drevesnih vrst, in sicer: smreke, kvebrača in kostanja z osnovnimi monomerami (stilben, katehin in galna kislina). Teoretična razlaga rabi praktičnemu delu, kjer so bili preučevani načini izdelave lužil oziroma obarvanih bakrovih kompleksnih spojin iz treh vrst tanina.

Title:Tannin stains on basis of cooper complex compounds
Abstract:
In the teoretical part the composition of hydrolysed and condensed tannins is presented. First ones based on gallic acid, and the others based on catechin. Both components are bonding itself in complicated compositions, which are chemically tied on sugars, what complicates their structure even more. Main accent is on the throughly studying of tannin of three different wood species:picea, quebracho and chestnut, with basic monomers (stylben, catechin and gallic acid). Teoretical interpretation is used in practical part where making the stains or dyed cooper complex compositions from three sorts of tannin were studied.
