✦ Synopsis

In 1937, 2. toxicarium liyske 01~s found in Formosan rice by Viyake (1).

Sinoe 1940 a series of studies on the toxicity of the fungus molded on rice have been extensively carried out by many workere (2), and one of us (Y.H.) isolated from the rioe a toxio yellow Oompound *iah nas named citreoviridin, since later 2. citreoviride was found to produce the same substanoe (3). Tsunoda found that 2. oehrosalmoneum Udagawa, which was found by Udagawa in 1959 (4), also produoed citreoviridin when being parasitized on rice (5). Citreoviridin (I), when being crystallized from methanol, forms yellow crystals, m.p. 107-ill', having a moleoular formula C23E3006' CH30H, whose methanol of crystallization is lost in storage. It exhibits hrz 388 nyl (E 48,OCC), 294 (27,100), 286sh (24,600), 234 (10,x)0), 204 (17
