Two new metabolites of Aspergillus flavus (Link)

Changes in mold damaged wheat flours stored at various temperatures. Fluorescent compounds: 4,6,8(14),22-ergostatetraen-3-one and its C24-ethyl analog

“…Yokotsuka et al (1967) found that about one-third of 73 industrial strains of Aspergillia produced autofluorescent compounds of the general formula Ci2H20N2O and CnHi8N202 that had Ri values by thinlayer chromatography (tic) comparable to those of aflatoxins. Bassir and Adekunle (1968) isolated two fluorescent compounds that had the molecular formula of C24H4403 and were identified as nonaromatic spatial isomers of hydroxy-conjugated fatty acids.…”

The histopathological effects of aflatoxin B1 and the palmotoxins B0 and G0 on the liver of the developing chick embryo

“…Toxins used were obtained from palmsap cultures of a strain of A. flavus (Link ex Fries) obtained from mouldy local legumes. They were isolated and purified by the method of Levi and Birker [8], Wiseman, Jacobson and Harmeyer [9] and Bassir and Adekunle [7] .…”

“…In this study, an attempt is made to define the hepatic embryotoxic characteristics of palmotoxins Bu and GO, previously identified as metabolites of Aspergilfus j7uvus [7] , and to compare the histopathological effects of these toxins with those of aflatoxin B, .…”

Comparative study of the fluorescent characteristics of solutions of aflatoxins and palmotoxins in chloroform

“…On the contrary, there are no reports on the fluorescent properties of palmotoxins B0 and G0 which are fluorescent metabolites of Aspergillus flavus (U.I. 81) cultured on a medium of palm sap (Bassir and Adekunle, 1968). Also, the fluorescent characteristics of aflatoxin B3 (Heathcote and Dutton, 1969) have never been spectrophotometer.…”
