After mimosa and quebracho extracts, chestnut extract is the third most important vegetable tannin used for leather production. It is produced only in Europe on the northern side of the Mediterranean sea. The extract is prepared by hot water extraction of the bark and timber, followed by spray-drying of the solution. Analysis shows that there are insignificant variations in extract quality between batches, so the extract can be used with modern automated leather production systems. The extract contains approximately 75 percent active tanning substances. The primary component is castalagin, along with smaller amounts of vescalagin, castalin, and vescalin. A castalagin-based pharmaceutical product is currently in use for prevention and treatment of diarrhea in pigs and cattle that is caused by changes in diet. The beneficial effect is due to prevention of water losses through mucous membranes. The castalagin may also form chelates with iron, which influences the reabsorption of the metal in the animal digestive tract.
除含羞草提取物和白坚木提取物外，栗木提取物是用于皮革生产的第三重要的植物单宁。它仅在地中海北部的欧洲生产。该提取物通过对树皮和木材进行热水提取，然后对溶液进行喷雾干燥来制备。分析表明，不同批次提取物的质量差异不显著，因此该提取物可用于现代自动化皮革生产系统。该提取物含有约75%的活性鞣质物质。主要成分是栗木鞣花素，还有少量的紫铆花素、栗木素和紫铆亭。一种基于栗木鞣花素的药品目前正用于预防和治疗猪和牛因饮食变化引起的腹泻。其有益效果是由于防止了通过粘膜的水分流失。栗木鞣花素还可能与铁形成螯合物，这会影响动物消化道中金属的重吸收。
