DETERMINATION OF AFLATOXIN B₁ IN GROUNDNUT EXTRACTS AND ITS MUTAGENICITY

PRASONG KOONANUWATCHAIDET^a and LOUISE Y.Y. FONG^b

Summary: Partially purified aflatoxin B₁(AFB₁) from ten batches of groundnut extracts in Hong Kong was quantitatively determined. Its mutagenesis was also assayed by S. typhimurium microsomal system. There is a good correlation between the presence of AFB₁ and its mutagenic activity in those extracts.
