Embodiment 1

[0053] Accurately weigh 1.0g of ginseng powder, put it into a centrifuge precipitation tube, add 10ml of ethanol, and perform ultrasonic extraction at below 20°C for 10 minutes. After that, centrifugation was performed for 5 minutes, and the supernatant was taken out. 10 ml of ethanol was added to the residue, extracted by shaking for 15 minutes, centrifuged again for 5 minutes, the supernatant was combined with the above-mentioned supernatant, and the volume was accurately adjusted to 25 ml with ethanol as the extraction solution.

[0054] Discovery manufactured by SIGMA-ALDRICH Co., Ltd. activated with ethanol in advance TM DSC-NH 2 10 ml of the extraction solution was placed in the SPE tube and allowed to flow out, followed by 10 ml of ethanol. The obtained effluent was concentrated under reduced pressure at 40°C, and the volume was accurately adjusted to 2 ml with ethanol. After standing at 0-5°C for 30 minutes or more, high-speed centrifugation was performed for 3 mi...

Embodiment 2

[0074] Accurately weigh 1.0g of ginseng powder, put it into a centrifugal precipitation tube, and add 10ml of extraction solvent, the extraction solvent is a solvent pre-added with EDTA and sodium sulfate in ethanol and left overnight, and ultrasonically extracted at below 20 ° C for 10 minutes . Then, centrifugation was performed for 5 minutes, and the supernatant was collected. 10ml of extraction solvent was added to the residue, extracted with shaking for 15 minutes, centrifuged again for 5 minutes, the supernatant was combined with the above-mentioned supernatant, and the volume was accurately adjusted to 25ml with the extraction solvent as the extraction solution.

[0075] Discovery manufactured by SIGMA-ALDRICH Co., Ltd. activated with ethanol in advance TM DSC-NH 2 10 ml of the extraction solution was placed in the SPE tube and allowed to flow out, followed by 10 ml of ethanol. 5 ml of the obtained effluent was concentrated under reduced pressure at 40°C, and the v...

Embodiment 3

[0091] Accurately weigh 1.0 g of yam powder, put it into a centrifugal precipitation tube, and add 10 ml of an extraction solvent, which is a solvent pre-added with EDTA and sodium sulfate in ethanol and left overnight, and ultrasonically extracted for 10 minutes at below 20°C . Then, centrifugation was performed for 5 minutes, and the supernatant was collected. 10ml of extraction solvent was added to the residue, extracted with shaking for 15 minutes, centrifuged again for 5 minutes, the supernatant was combined with the above-mentioned supernatant, and the volume was accurately adjusted to 25ml with the extraction solvent as the extraction solution.

[0092] Discovery manufactured by SIGMA-ALDRICH, which is preactivated with ethanol TM DSC-NH 2 10 ml of the extraction solution was placed in the SPE tube and allowed to flow out, followed by 10 ml of ethanol. 5 ml of the obtained effluent was concentrated under reduced pressure at 40°C, and the volume was accurately adjus...

Abstract

The invention relates to an analysis method of ambam. The invention provides a method for directly analyzing ambam remaining in a sample by using GC / MS (Gas Chromatography / Mass Spectrometry). According to the method for analyzing the ambam, the gas chromatography-mass spectrometer is used for analyzing the ambam remaining in a sample, and the method comprises the step of extracting the ambam from the sample by using alcohol with the carbon atom number of 1-3 as an extracting solvent.

Description

technical field [0001] The present invention relates to a method for analyzing dysenium remaining in a sample using a gas chromatography mass spectrometer (GC / MS). Background technique [0002] Amobam is an ethylene bis-dithiocarbamate-based organosulfur bactericide, also known as Amobam, Amobam, Jeans, and Amobam. Ammonium (ダイセンステンレス), Ethylenebis(Ammonium Dithiocarbamate), Ethylenebis(Ammonium Dithiocarbamate), 1,2-Ethylenebis(Ammonium Carbamate Dithiocarbamate) (1 , 2-エタンジイルビス (カルバモジチオacid アンモニウム), ethylenebis(dithiocarbamic acid) diammonium, N,N'-ethylenebis(dithiocarbamic acid) diammonium, etc. are named. [0003] Dysenium has the formula: [0004] [Chemical formula 1] [0005] [0006] The structure represented is a compound that is easily decomposed, so it has been known so far that the 14 C marked 14 C-labeled to analyze desenium (Non-Patent Document 1), but no method for directly analyzing desenium has been established. [0007] In "Uniform Testing Method f...
