Definitions
- Extracts of residual animal drugs in livestock and fishery products Extracts of residual animal drugs in livestock and fishery products
- the present invention relates to an extract of a drug for residual animals. More specifically, the present invention relates to an extract used for measuring veterinary drugs remaining in livestock products.
- a provisional standard value for the residual amount of veterinary drugs exceeding 200 items will be established, but the official method of analyzing these drugs individually will not be able to deal with time and labor. Therefore, it is desired to establish a method for analyzing residual substances that can easily and quickly analyze multiple components.
- antibacterial substances eg antibiotics, synthetic antibacterials, etc.
- antibacterial substances are increasing in both type and use due to the current mass breeding method, and may remain in livestock and fishery products. Has been pointed out.
- antibiotics such as spiramycin, tilmicosin, gentamicin, spectinomycin and neomycin, and highly polar compounds such as quinoxaline carboxylic acid and cyromazine are used.
- a method for simultaneous analysis of multiple components has not been developed and is a problem. In order to perform such multi-component simultaneous analysis, it is necessary to extract a plurality of residual veterinary drugs at the same time from the livestock and marine products as samples.
- the present invention made to solve the above problems comprises 0.05 to 1% (w / v, the same shall apply hereinafter) of metaphosphoric acid, and comprises a buffer solution having a pH of 5.5 to 7.5.
- This is an extract of drugs for residual animals in livestock and fishery products.
- it is preferably used for extraction when the residual veterinary drug is an antibacterial substance, and it is preferable to use a Makilben buffer as the buffer.
- antibacterial substances among veterinary drugs are an obstacle to simultaneous extraction because the conditions under which individual substances exist stably differ. From this point of view, the present inventors conducted the following tests in order to eliminate such obstacles.
- Target 1 is selected from 21 compounds such as tetracytalin that are soluble in organic solvents.
- Target 2 is an aminoglycoside antibiotic that is highly polar and difficult to dissolve in organic solvents (streptomycin, dihi Drosteptomycin, spectinomycin and gentamicin) were selected.
- the present inventors have studied the liquidity and metaphosphoric acid concentration of the extract variously, and even if the liquidity is near neutral, a specific metaphosphoric acid can be obtained. More specifically, by using an extract containing 0.5 to 1% metaphosphoric acid and having a pH of 5.5 to 7.5. In particular, it has become clear that antibacterial substances can be extracted all at once without impairing their stability. It should be noted that such a buffer solution containing metaphosphate with a pH value of However, the presence of metaphosphate as a compound was considered to be important for the extraction effect.
- any buffer solution can be used as long as it does not inhibit the extraction of animal drugs from livestock and marine products.
- Makilben buffer solution Hepes buffer solution, Selensen buffer solution,
- a Kracools buffer solution For example, a Kortov buffer solution, and the like, and a Makilben buffer solution is preferably used.
- the pH of the extract is adjusted to 5.5 to 7.5, preferably 6.0 to 7.0, in order to prevent denaturation of the animal drug to be extracted.
- the metaphosphoric acid concentration is adjusted to 0.05 to 1%, preferably 0.1 to 0.5%. If the metaphosphate concentration is less than 0.05%, gentamicin may not be extracted.
- the extract of the present invention can be prepared by adding metaphosphoric acid to the above-mentioned appropriate pH buffer so as to have the above-mentioned concentration.
- a chelating agent such as EDTA or an aqueous organic solvent such as methanol may be added as necessary.
- the above-mentioned buffer solution: chelating agent: methanol is used in an extract solution having a ratio of about 15: 1: 4.
- the method of using the extract of the present invention can be used in the same manner as the conventional drug extract for residual animals.
- the extract of the present invention is added to a livestock product that is a sample to be homogenized. After that, the extract can be obtained by separation by a conventional means such as centrifugation.
- the amount of the extract to be used with respect to the above-mentioned specimen is such that the ratio of the specimen to the extract is 1 : 1 to 10 (w, v ratio, the same shall apply hereinafter), preferably 1: 2 to 8, more preferably 1: 2.5. Adjust to about ⁇ 5. If the amount of extract for sample 1 is less than 1, extraction may be insufficient, and if it exceeds 10, there is no problem in terms of extraction, but the amount of extract may increase and the operation may become complicated There is.
- Samples of livestock and fishery products include livestock meat (eg beef, pork, chicken, salmon, lamb, ducks, etc.) and seafood (eg hamachi, Thai, puffer, shrimp, eel, carp, trout, oysters, etc.) Can be mentioned.
- livestock meat eg beef, pork, chicken, salmon, lamb, ducks, etc.
- seafood eg hamachi, Thai, puffer, shrimp, eel, carp, trout, oysters, etc.
- animals collected from nature can be used as specimens.
- the extract thus obtained is purified according to a conventional method such as column purification and then used in a conventional manner. Residual veterinary drugs are measured using a measuring device.
- the purification method for example, c 18 solid phase extraction column is used, this time, it may also be added to HFBA a ion pair reagent in the extract to adsorb on the column les.
- Residual animal drugs can be measured by high performance liquid chromatography / mass spectrometry.
- the extract of the present invention since pH is in a neutral region, it can be extracted simultaneously and efficiently without impairing the stability of a plurality of veterinary drugs, and gentamicin is contained because it contains metaphosphoric acid. There is an effect that extraction can be performed. Therefore, by using the extract of the present invention, it becomes possible to simultaneously extract drugs for residual animals in livestock and fishery products, and it is possible to speed up and simplify the measurement of residual amounts.
- the addition recovery test was conducted by the following method.
- the aminoglycoside addition recovery test was conducted at an addition amount of 200 ppb in consideration of the residual standard value stipulated in the Food Sanitation Law.
- a standard sample of aminoglycoside antibiotics (streptomycin, dihydrostreptomycin, spectinomycin, gentamicin) was added to a concentration of 200 ppb or not added (control) Specimen (beef ) 5 g was extracted by homogenizing with 25 ml of a 0.1% metaphosphoric acid-containing pH 7 makilben solution / EDTA / methanol mixed solvent.
- the supernatant after extraction was diluted with 25 ml of 10 mM HFBA, added to a C 18 solid phase extraction column (12 cc 500 rag), washed with 5 ml of 5 mM HFBA, and eluted with 20 ml of HFBA / MeOH (1: 1).
- Example 2 The measurement was carried out as in Example 1, except that a 0.3% metaphosphoric acid-containing pH 6 makilben solution was used instead of the 0.1% metaphosphoric acid-containing pH 6 makilben solution.
- Example 2 The measurement was carried out as in Example 1 except that a 0.5% metaphosphoric acid-containing pH 6 makilben solution was used instead of the 0.1% metaphosphoric acid-containing pH 6 makilben solution.
- Example 2 The measurement was carried out as in Example 1 except that 1% metaphosphoric acid-containing pH 6 makilben solution was used instead of the 0.1% metaphosphoric acid-containing pH 6 makilben solution.
- Example 2 The measurement was carried out as in Example 1, except that the extraction was performed using a pH 6 makilben solution containing no metaphosphoric acid instead of the pH 6 makilben solution containing 0.1% metaphosphoric acid. Comparative Example 2
- Example 2 The measurement was carried out as in Example 1 except that a 0.1% metaphosphoric acid-containing pH 6 makilben solution was used instead of the 0.1% metaphosphoric acid-containing pH 6 makilben solution.
- Table 1 shows the results of the above tests. As shown in Table 1, in Example 1, the recovery rate for all steps was about 60% for dihydrostreptomycin, about 50% for streptomycin and spectinomycin, and about 4% for gentamicin. It was a little bit cheaper. The coefficient of variation for the four specimens was in the 10% range, and good reproducibility was obtained. In addition, almost the same results were obtained in Example 2, Example 3, and Example 4. On the other hand, in Comparative Examples 1 and 2, the recovery rate of gentamicin was low and could not be used for measurement. In Example 1, Example 2, Example 3, and Example 4 above, the mouth-mouth matogram obtained by LC / MS / MS was observed. It was easy to detect and it was difficult to produce false positives. In addition, since the baseline was low, it was found that the lower limit of quantification obtained from S / N was possible to around tens of ppb. table 1
- the average value is the average of 9 measurements.
