COMPOSICIÓN QUÍMICA= Chemical composition: The rhizome of Typha dominguensis Kunth grown in a clay soil has starch 11.55, albumin 0.35, fatty oil 0.29, resin 0.85, essential oil 0.13, gummy substances 0.88, tannin 5.45, glucose 1.22, inorg. salts 1.73, org. acids 0.25, cellulose 8.68 and H2O 68.6%; the compn. varies with the kind of soil. The fatty oil consists principally of palmitic and oleic acids and contains an unidentified toxic principle which has purgative and emetic properties. The essential oil (d20 0.9065-0.9165, n20 1.4885, [alpha]20 - 5degrees20' + 7degrees45') consists principally of thymol together with alpha-pinene, a phenol C8H11O2, and a lactone C14H22O2. This oil acts (in vitro) as a medium anthelmintic. The resin (d. 1.06-1.11, acid no. 22-36, sapon. no. 60) has diuretic properties. Ash contains 35% K2O and 20-28% SiO2. Empirically prepd. infusions have proved efficacious in cases of ascites, and appear to be of value in the treatment of rheumatism, eczema and verminosis.
