Thin layer chromatographic determination of aflatoxin B1 in eggs: collaborative study. 1978

S Nesheim, and M W Trucksess

The thin layer chromatographic method of Trucksess et al. for aflatoxin B1 in eggs was collaboratively studied. Each collaborator analyzed 3 known practice samples and 9 unknown samples containing added aflatoxin B1 at 0, 0.05, 0.10, and 0.30 ng/g. For 9 collaborators, recoveries for the 3 positive levels were: 0--0.13 ng/g (average 98%, coefficient of variation (C.V.) 83%), 0.05--0.18 ng/g (average 102%, C.V. 36%, and 0.11--0.42 ng/g (average 93%, C.V. 31%), respectively. The method has been adopted as official first action.

D004531	Eggs	Animal reproductive bodies, or the contents thereof, used as food. The concept is differentiated from OVUM, the anatomic or physiologic entity.
D000348	Aflatoxins	Furano-furano-benzopyrans that are produced by ASPERGILLUS from STERIGMATOCYSTIN. They are structurally related to COUMARINS and easily oxidized to an epoxide form to become ALKYLATING AGENTS. Members of the group include AFLATOXIN B1; aflatoxin B2, aflatoxin G1, aflatoxin G2; AFLATOXIN M1; and aflatoxin M2.	Aflatoxin
D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
