Biochemical Technology Topics: Identification of Tannin Compounds
1. Preparation of test solution:
Take gallnut (including hydrolyzable tannin), catechu (containing condensed tannin), gallic acid (purine tannin extract), a small amount (about 0.1 g) in a large test tube, add about 10ml of distilled water, heat to boil, Filtration, the filtrate was tested as follows:
2. General reaction of enamel (identification of enamel and pseudo sputum)
(1) Sensory test: Take the prepared enamel and pseudo enamel solution, taste the taste, and check whether the solution is acidic reaction with litmus paper.
(2) Ferric chloride reaction: Take 1~2ml of the prepared enamel solution (gallium solution or catechin solution) and pseudo sputum solution (food acid solution), respectively add ferric chloride test solution, and produce enamel Green or blue-black reaction or precipitation; pseudo-enamel produces a blue reaction.
(3) Precipitating protein reaction: Take 1~2ml of each of the sputum solution and the pseudo sputum solution, respectively, into a few drops of gelatin solution, and the sputum technique immediately produces a precipitation reaction.
(4) Alkaloid reaction: Take 1~2ml of enamel solution and pseudo enamel solution, respectively, add 0.1% aqueous solution of caffeine, and the enamel solution will produce a precipitation reaction, and the pseudo enamel will not produce a precipitation reaction.
3. Identification of the difference between hydrolyzable hydrazine and condensed tannin
(1) Eosin reaction: Take a gallnut infusion (containing hydrolyzable tannin), 2 ml of catechu infusion (containing condensed tannin), add 0.5 ml of hydrochloric acid, and boil for about 30 minutes. The hydrolyzable tannin does not precipitate, and the condensed tannin has a red precipitate.
(2) Ferric chloride reaction: take 1~2ml of gallnut infusion and catechu immersion, add several drops of ferric chloride test solution, hydrolyze enamel blue or black blue reaction, condensate tannin A blackish green reaction.
(3) Bromine water reaction: Take 1~2ml of the infusion solution of the gallnut infusion solution, and add a few drops of bromine water respectively to hydrolyze the shoe cap without causing precipitation reaction, and the condensation enamel produces precipitation.
(4) Lime water reaction: Take 1~2ml of gallnut infusion and catechu infusion, add several drops of fresh lime water respectively, hydrolyze the enamel to appear blue-grey precipitate, and condense tannin to form brown precipitate.
(5) Reaction with lead acetate in acetic acid solution: Take 1~2ml of gallnut infusion and catechu infusion, add several drops of acetic acid solution, shake and then add several drops of lead acetate solution, which can hydrolyze tannin to produce flocculent Precipitation, condensation of tannins without precipitation.
