Forty-one samples of beer were analyzed for fumonisins B1 and B2 (FB1 and FB2) using an immunoaffinity column cleanup followed by liquid chromatographic (LC) analysis. These samples included three later brand resamplings. All LC analyses were carried

A simple extraction procedure was applied to the analysis of canned/packaged white nuts and Ginkgo biloba extracts. Extraction by shaking with water at room temperature was more convenient to use than a previously published Soxhlet procedure for anal

The reaction of α‐ and β‐thujones with dansylhydrazine (DNSH) was studied using reversed phase liquid chromatography (LC) with fluorescence detection. The derivatization procedure, although slow, was applied for determination of α‐thujone in

Hot water extracts of Ginkgo biloba seeds were analyzed for the presence of ginkgotoxin (4′-O-methylpyridoxine) by reversed-phase liquid chromatography (LC) using methanol–0.05M KH2PO4 (1 + 9, v/v) adjusted to pH 3 as mobile phase. Detection was

A survey was conducted to evaluate fumonisins FB1 and FB2 in Uruguayan corn products. Sixty- four samples of different local brands were purchased from retail stores during a 15-month period and analyzed for FB1 and FB2 by methanol-water extraction,

Because the natural occurrence of fumonisins is so far known almost exclusively in corn, we have limited our investigations on their stability to corn-based foods. In these studies, distinction must be made between real losses, binding, and any matri

Fumonisins B1 and B2 are closely related mycotoxins produced by Fusarium moniliforme, F. proliferatum, and related species. Disadvantages of 2 fluorescence derivatizing reagents currently used for liquid chromatography (LC) are instability of the der
