Fumonisin B2

The purpose of this study was to measure the potential levels of fumonisin B1 (FB1) and fumonisin B2 (FB2) contamination in several herbal teas and medicinal plants that are consumed regularly in Turkey. FB1 and FB2 were detected using high-performance liquid chromatography with fluorescence detection after derivatization with o-phthaldialdehyde. A total of 115 commercially available herbal tea and medicinal plant samples were analyzed. The recoveries in black tea were 86.9 ± 8.42% for FB1 and 102 ± 6.80% for FB2 spiked with 1 μg/g of each analyte. Similarly, the mean recovery results in lime (linden) for FB1 and FB2 were 85.2 ± 9.76% and 78.6 ± 5.67%, respectively. The minimum detectable amounts for the o-phthaldialdehyde derivatives of FB1 and FB2 were 0.025 μg/g (1 ng injected) and 0.125 μg/g (5 ng), respectively. FB1 was detected in two samples (0.160 and 1.487 μg/g), and FB2 was detected in none of the samples.

The purpose of this study was to investigate fumonisin B1 (FB1)- and B2 (FB2)-contaminated corn and corn-based products consumed especially by the Turkish population. FB1 and FB2 were detected using high-performance liquid chromatography with fluorescence detection. The total number of commercially available corn and corn-based product samples analyzed in this research was 82. The recoveries were found to be 94.4 ± 4.62% and 86.5 ± 4.86% for cornmeal spiked with known amounts of FB1 and FB2 (1 ppm), respectively. The minimum detectable amount for the o-phthaldialdehyde derivatives of FB1 and FB2 were 1 ng and 5 ng, respectively. Detected levels of FB1 were between 0.25 ppm and 2.66 ppm in 25.6% of the samples, and detected level of FB2 in a single cornmeal sample was 0.55 ppm.
