 "Very long and creeping; about 2 Mm. (1/2 inch) thick; as met with in the shops, cut into sections about 1 Cm. (2/5 inch) long; smooth, but wrinkled; hollow in the center, straw-yellow; inodorous; taste sweetish"(U. S. P.) The rhizome of couch-grass, according to Ludwig and Miller (Jahresb. der Pharm., 1872, p. 22, and 1873, p. 25), contains laevulose (from 2.5 to 3.3 per cent); triticin, a very hygroscopic, laevo-rotatory substance allied to inulin, soluble in diluted alcohol and water, insoluble in ether, little soluble in strong alcohol. Upon hydrolysis with water or diluted acids, it yields laevulose. Other constituents of the rhizome are acid malates, and about 11 per cent of a nitrogenous gummy substance forming insoluble compounds with neutral and with basic lead acetate. The dried rhizome yields 4.5 per cent of ash, containing much silicic acid. (For some possible economic uses of the rhizome, see Plauchud, Jour. Pharm. Chim., 1877, p. 389.)

 Couch-grass rhizome contains about 7 to 8 per cent of Triticin (a carbohydrate resembling Inulin) and yielding levulose on hydrolysis. It appears to occur in the rhizome of other grasses, and possibly is widely diffused in the vegetable kingdom. Sugar, Inosite, Mucilage and acid malates are also constituents of the drug. Lactic acid and mannite may occur in an extract of the rhizome, but are understood to be fermentation products. Starch is not present and no definite active constituent has yet been discovered. The rhizome leaves about 4 1/2 per cent ash on incineration.
