Punica granatum L. Shi Liu Pi (Pomegranate) (pericarp, root bark) Pelletierine, isopelletierine, methylisopelletierine, methyl-pelletierine, pseudopelletierine, gallotannic acid, sitosterol, ursolic acid, maslinic acid, elegic and gallic acid.33-450 This herb is toxic. Purges intestinal parasites. [Pg.136]

Inks.—Formerly all writing inks except so-called India ink, which is a carbon product, were made by the treatment of ferric salts with tannin or tannic acid. The green solution produced with excess of the iron salt becomes black on drying and exposure to the air. Such iron inks may be bleached by means of oxalic acid which reduces the colored ferric compound, produced with the gallotannic acid, to a colorless compound. At the present time many writing inks are made from aniline dyes. These are not bleached with oxalic acid, but are... [Pg.725]

Gallotannic acid separated from gall-nuts by extraction with alcohol, ether, and water, is obtained as a colorless amorphous mass or light yellow scales. It is soluble in six parts of cold water, and is precipitated by dilute hydrochloric acid or sodium... [Pg.540]

Gallotannic acid has been synthesized by a method which furnishes evidence of its structure. It is formed by the action of the potassium salt of gallic acid on bromoprotocatechuic acid ... [Pg.541]

The formula assigned to gallotannic acid is in accord with its reactions. The acid is converted into gallic acid by hydrolysis, forms a penta-acetyl derivative when heated with acetic anhydride, and is converted into the amide and the ammonium salt of gallic acid when boiled with a solution of ammonia. [Pg.541]

The other type of ink used historically is called iron gall. The iron was usually added in the form of iron sulfate (Fe +S04 ") gall refers to gallotannic acid that was extracted... [Pg.226]
