Abstract

The not comminuted grain (10 g) is extracted for 24 hrs (25 degrees C) with 5 ml methanol (shaking machine), then the fluid phase is separated by centrifugal filtration and directly injected into the GC (10 mu). The GC starting temperature (60 degrees C) is adjusted by cooling the oven with Co2. Yield: EO 73% (concentr. range 25 ppm); ECH 93% (concentr. r. 50 ppm); EG 99% (conc. r. 50 ppm). Standard deviation: EO s = +/- 1,70 ppm (N = 24, conc. r. 10 ppm), ECH s = +/- 1,15 ppm (N = 24, conc. r. 20--30 ppm), EG s = +/- 0,62 ppm, (conc. r. 15--30 ppm, N = 24).
