7.2.1A.BC1 group: put vi18 cattle into fixed rack F.7.2.2. Transfer 100 mL of lipid pre-wash solution to the top of the chicken heart, and then transfer 3 mL of the extract to about 1 mL of the following group. 7.2.3. Add about 1 mL of anhydrous trichloroethane to a height of about 2 cm in a silver bath, and connect the sample to the nitrogen prep section of the ScP-Pak, and move the sample to the holder at the back of the bottle. 7.2.1. Pre-wash the sample with 4 mL of lipid extract (3, 1). When the sample reaches the lower end, slowly release the sample and do the following: .2.2) Transfer to the purification chamber: wash the sample with 2 tons of ethyl acetate each time for a total of 3-1 times. Store the sample in a tray and add 1:5) 1 mL of ethanol to the tandem rod. Elute the drug with 1 mL of ethanol (3+1) and add 0.5% water to the solution. For the 2B and C group drugs, add 5 mL of ethane each time and rotate in a water bath. Change the solution several times until the solution volume is about 1 mL. The mixture can be used for gas chromatography-mass spectrometry (GC-MS). Place the concentrated drug in a 3-2 mL atmosphere and blow it with ethyl acetate + water for a total of 1 mL. Determine by pressure chromatograph-mass spectrometry. 7.3. 7.3. 1 Gas chromatography-mass spectrometry 7.3. 1 Strip

In order to achieve the desired result, the internal standard method is used as the single drink. To reduce the influence of H quality, the internal standard method should be replaced with chlorine: to ensure that the standard matrix is not mixed, the sample should be injected again. Standard. Working principle: The concentration of the standard should be close to that of the chemical to be tested. The four groups of standard substances A, H, C, are separated and measured by G-MS.

7.3.2.2 Qualitative determination
.mir.>
The product is read through the projection chromatography and the mass spectrometer is connected to the measurement unit for each component to be measured separately. When the sample is selected for measurement, if the retention time of the calibrated chromatogram is consistent with that of a certain matrix marker, and the ratio of the two selected pairs of separations is consistent, it is called determination that this retention time exists in the sample.
7. 3. 2. 3 Quantitative determination
In this method, the liquid chromatography-tandem mass spectrometry is used to quantify the sample by external standard method. In order to reduce the influence of the base on the determination, a series of base pressure standard working solutions are prepared with blank sample solution, and the standard working solution is used to prepare the standard line + and ensure that the measured sample is within the linear cell pressure of the instrument: The E group standard substances detected by this method are shown in the TC-MSMS.

7.1 Vibrate
Weigh 30 μg of sample (precise single 2.1R) Fml and insert it into the sample for 20m! BHT, use a tissue crusher at 500/, extract uniformly, add 5 sodium polychloride, extract with carbon dioxide for 1m, put the tubes into two centrifuges, centrifuge at 00r:min, take 20ml of supernatant (equivalent to 10ml) for purification: 7.2 Purification

7.2.1A.BC1 group: put vi18 cattle into fixed rack F.7.2.2. Transfer 100 mL of lipid pre-wash solution to the top of the chicken heart, and then transfer 3 mL of the extract to about 1 mL of the following group. 7.2.3. Add about 1 mL of anhydrous trichloroethane to a height of about 2 cm in a silver bath, and connect the sample to the nitrogen prep section of the ScP-Pak, and move the sample to the holder at the back of the bottle. 7.2.1. Pre-wash the sample with 4 mL of lipid extract (3, 1). When the sample reaches the lower end, slowly release the sample and do the following: .2.2) Transfer to the purification chamber: wash the sample with 2 tons of ethyl acetate each time for a total of 3-1 times. Store the sample in a tray and add 1:5) 1 mL of ethanol to the tandem rod. Elute the drug with 1 mL of ethanol (3+1) and add 0.5% water to the solution. For the 2B and C group drugs, add 5 mL of ethane each time and rotate in a water bath. Change the solution several times until the solution volume is about 1 mL. The mixture can be used for gas chromatography-mass spectrometry (GC-MS). Place the concentrated drug in a 3-2 mL atmosphere and blow it with ethyl acetate + water for a total of 1 mL.

In order to achieve the desired result, the internal standard method is used as the single drink. To reduce the influence of H quality, the internal standard method should be replaced with chlorine: to ensure that the standard matrix is not mixed, the sample should be injected again. Standard. Working principle: The concentration of the standard should be close to that of the chemical to be tested. The four groups of standard substances A, H, C, are separated and measured by G-MS.

7.3.2.2 Qualitative determination
.mir.>
The product is read through the projection chromatography and the mass spectrometer is connected to the measurement unit for each component to be measured separately. When the sample is selected for measurement, if the retention time of the calibrated chromatogram is consistent with that of a certain matrix marker, and the ratio of the two selected pairs of separations is consistent, it is called determination that this retention time exists in the sample.
7. 3. 2. 3 Quantitative determination
In this method, the liquid chromatography-tandem mass spectrometry is used to quantify the sample by external standard method. In order to reduce the influence of the base on the determination, a series of base pressure standard working solutions are prepared with blank sample solution, and the standard working solution is used to prepare the standard line + and ensure that the measured sample is within the linear cell pressure of the instrument: The E group standard substances detected by this method are shown in the TC-MSMS.
