[Gas chromatography with electron capture detector for determining DON and NIV in scabby wheat].
DON and NIV were extracted with methanol-water (3:1) and purified by Florisol column. The mycotoxins in the column eluates were derived by TMS reagent and then analysed by gas chromatography with electron capture detector. The average recoveries of DON and NIV, as counted into wheat, at 100, 500, 1,000 and 2000 ppb were 81.2% and 74.5% respectively. The limits of detection of toxins of wheat were 10 ppb for both DON and NIV.
