Tayuya. Dermaphylla pendulina.

Tayuya.—The root of the Dermophylla (Cayaponia) pendulina Manso (Fam. Cucurbitaceae), is used in Brazil, under the name of tayuya, in syphilis, etc. (N. R., 1877, 234); also, under the same name, the root of the Trianosperma ficifolia Mart. (Cayaponia Martiana Cogn.), also of the Fam. Cucurbitaceae (P. J., x, 667), and probably various other roots. In C. ficifolia Cogn. two alkaloids, trianospermine and trianospermitine, and a bitter principle, tayuyin, have been found by Peckoldt (P. J., x, 667), and in T. dermophylla a green resin, bitter extractive, and tannic acid were found by the same investigator. (B. G. T., lxxxiv, xci. See also Proc. A. Ph. A., xxiv.)
