When a mixture of ground nutmeg and ground cinnamon leaves was subjected to thin layer chromatography (TLC), spots that hampered detection of aflatoxins appeared on the TLC plate. These spots represented oxidation or heat‐induced degeneration products of the cinnamon leaves. Between 1986 and 1991, 67 samples of nutmeg, that were commercially available in Japan, were examined for aflatoxin contamination. Aflatoxins were detected in 29 (43%) of the 67 samples.
