[a. G. phallin (R. Kobert 1891, in St. Petersb. med. Wochenschr. XVI. 472/2), f. mod.L. phalloides (see phalloidin): see -in1, -ine5.]
A hæmolytic substance present in the death cap toadstool, Amanita phalloides, and formerly thought to be its poisonous principle.
1897Trans. Brit. Mycol. Soc. I. 27 Professor Kobert..has given the name of phalline to the poisonous substance present in Amanita phalloides, Fries. Ibid. 28 Phalline is a very powerful agent..in causing the dissolution of the red corpuscles of the blood. 1930Lancet 1 Feb. 228/1 The toxin of tetanus is checked by La Bourboule water and not by Mont Dore, phallin poison by Mont Dore water and not by La Bourboule. 1965Bell & Coombe tr. Strasburger's Textbk. Bot. 508 Familiar Agaricaceae:..Amanita phalloides.., deadly poisonous with toxic glucosides (phallin) and peptides (phalloidin, amanitin). 1972T. & O. Wieland in S. J. Ajl et al. Microbial Toxins VIII. x. 252 A hemolytic agent..was obtained from A. phalloides as early as 1891 by Kobert and was called ‘phallin’. It has recently been reinvestigated by Fiume (1967), who..stated that, in addition to a hemolytic action, a cytotoxic effect on cultures of cells of KB line and of human amnion cells occurred. This substance, whose chemical nature has not yet been established, is presumably destroyed in the gastrointestinal tract and, therefore, cannot be responsible for lethality of the mushroom. |
