- CMPT solvent Three types of bases (potassium carbonate, collidine, pyridine (Pyridine)) to search for a base and a solvent suitable for excimer fluorescence derivatization reaction of histamine using CMPT, The state of the solution was observed when CMPT was dissolved in seven types of solvents (DMF (N, N-dimethylformamide), DMSO (Dimethyl sulfoxide), THF (tetrahydrofuran), ACN (acetonitrile), ethyl acetate, chloroform, acetone)). .
- DMF N, N-dimethylformamide
- DMSO Dimethyl sulfoxide
- THF tetrahydrofuran
- ACN acetonitrile
- ethyl acetate chloroform, acetone
- Table 1 shows that DMF is excellent as a solvent for CMPT.
- the bases of potassium carbonate, collidine, and pyridine were not different in solubility of CMPT, precipitation of CMPT was observed when water was added in a solution using potassium carbonate. As will be described later, it is not preferable to use potassium carbonate, considering that water is added in the pretreatment for separating histamine in soy sauce.
- the intensity of excimer fluorescence was higher with pyridine than with collidine. Therefore, in this example, pyridine was employed as a base used for histamine analysis.
- FIGS. 2 and 3 are obtained by dissolving 10 ⁇ L of histamine in ACN solution in 3 ⁇ L of pyridine and 20 ⁇ L of CMPT in DMF, and then derivatizing histamine with HPLC.
- Fig. 3 shows the results of separation of fluorescent derivatized histamine and detection of its excimer fluorescence intensity.
- FIG. 2 shows the relationship between the reaction time and the fluorescence intensity (area) when the CMPT concentration is 20 mM and the reaction temperature is 50 ° C.
- FIG. 3 shows the relationship between the CMPT concentration and the fluorescence intensity when the reaction temperature is set to 50 ° C. and the reaction time is set to 20 minutes.
- the fluorescence intensity gradually increased until the reaction time was 20 minutes, but the fluorescence intensity hardly changed after 20 minutes. Further, as can be seen from FIG. 3, the fluorescence intensity gradually increased in the concentration range up to 20 mM, but the fluorescence intensity hardly changed in the concentration range higher than 20 mM. From the viewpoint of shortening the time required for histamine analysis and reducing the amount of CMPT used for histamine analysis, the reaction time for excimer fluorescence derivatization in histamine analysis according to this example was set to 20 minutes, and the CMPT concentration was set to 20 mM.
- FIG. 4 (a) The HPLC analysis result of histamine (50 ppm standard product) performed under these conditions is shown in FIG. 4 (a), and the HPLC conditions at this time are shown in FIG. 4 (b). Further, from FIG. 4 (c) showing the result of MS analysis of a substance in which excimer fluorescence was detected by HPLC analysis, it was confirmed that a substance in which CMPT2 molecules were bonded to one histamine molecule was generated.
- CMPT was dissolved in DMF to prepare a solution. This solution was stored at room temperature, and then histamine was fluorescently derivatized using this solution. The obtained fluorescent derivatized histamine was separated using HPLC, and the intensity of the excimer fluorescence was determined. As a result, the relationship between excimer fluorescence intensity and storage time was as shown in FIG. As can be seen from FIG. 5, CMPT was able to be fluorescently derivatized without lowering its reactivity with histamine for 40 days or more even in a DMF solution. This indicates that CMPT is superior in storage stability in a solution state as compared with conventional excimer fluorescent derivatization reagents.
- Magnesium sulfate is added to salt out proteins and the like, and sodium hydroxide is added to adjust the pH and increase the amount of molecular histamine.
- the present inventor examined pretreatment conditions suitable for derivatizing histamine with CMPT with reference to this pretreatment method. Specifically, when a sample containing histamine having a known concentration is separated into an acetonitrile layer and an aqueous layer, the ratio of histamine recovered in the acetonitrile layer (recovery rate (%)) is set to a sodium hydroxide concentration of 1. When changed to ⁇ 4M (FIG. 6B), both unheated acetonitrile and heated acetonitrile were used (FIG. 6C).
- the recovery rate of histamine was 25% when the concentration of sodium hydroxide was 1M, but the recovery rate of histamine was 45% in the range of 2M to 4M. From the above, it is considered that the concentration range of 2M to 4M is appropriate for sodium hydroxide used for the pretreatment of soy sauce.
- the peak shape of the fluorescent derivatized histamine is symmetrical, but when unheated ACN is used, the fluorescent derivatized histamine is asymmetrical. It was a shape. This is probably because the protein in the sample could not be sufficiently removed when non-heated ACN was used, and the fluorescence peak of the protein-derived substance overlapped with the fluorescence peak derived from histamine. Therefore, it seems that it is preferable to use heated ACN for pretreatment of soy sauce rather than unheated ACN.
- Table 2 shows the detection limit (Limit of detection, LOD), lower limit of quantitation (Limit of quantitation, LOQ), linearity, and calibration curve range at this time. From Table 2, it was found that the histamine analysis according to this example can obtain sufficient linearity and sensitivity to analyze histamine in soy sauce.

Abstract
Description
なお、ここではピレン試薬を用いてポリアミンを分析する場合について説明したが、最近では、1分子中にアミノ基とフェノール性水酸基を有するチラミン等のモノアミンもピレン試薬で蛍光誘導体化されることによりエキシマーを形成することが分かっている。従って、上述したピレン試薬を用いてモノアミンを分析する場合にも同様の問題が生じる。
具体的には、本発明に係る蛍光誘導体化試薬は、以下の一般式(1)
図1に示すように、2,4-ジクロロ-6-メトキシ-1,3,5-トリアジン(2,4-dichloro-6-methoxy-1,3,5-triazine)1当量と1-ピレンブタノール(1-pyrenebutanol)1当量に、コリジン(Collidine)1.2当量を加え、室温で24時間放置した。この溶液を高速液体クロマトグラフ(HPLC装置)で分離した後、再結晶化して精製した。得られた生成物をNMR分析及び質量分析(MS)で確認したところ、以下の式で表される化合物(CMPT)であると同定された。
CMPTを用いたヒスタミンのエキシマー蛍光誘導体化反応に適した塩基及び溶媒を探索するために3種類の塩基(炭酸カリウム、コリジン(Collidine)、ピリジン(Pyridine))と、7種類の溶媒(DMF(N,N-dimethylformamide)、DMSO(Dimethyl sulfoxide)、THF(tetrahydrofuran)、ACN(acetonitrile)、酢酸エチル、クロロホルム、アセトン)にCMPTを溶かしたときの溶液の状態を観察した。その結果を表1に示す。表1中「×」は、CMPTが完全に溶解しなかった塩基と溶媒の組み合わせを示す。
図2及び図3は、ヒスタミンのACN溶液10μLをピリジン3μL、CMPTのDMF溶液20μLに溶解し、ヒスタミンを蛍光誘導体化した後、HPLCで蛍光誘導体化ヒスタミンを分離してそのエキシマー蛍光強度を検出した結果を示す。図2は、CMPTの濃度を20mMに、反応温度を50℃に設定したときの、反応時間と蛍光強度(面積)との関係を示す。また、図3は反応温度を50℃に、反応時間を20分に設定したときの、CMPTの濃度と蛍光強度の関係を示す。図2から分かるように、反応時間が20分までは蛍光強度が徐々に増加したが、20分以降は蛍光強度はほとんど変化しなかった。また、図3から分かるように、20mMまでの濃度範囲では蛍光強度が徐々に増加したが、20mMよりも大きい濃度範囲では蛍光強度はほとんど変化しなかった。ヒスタミン分析に要する時間の短縮、ヒスタミン分析に使用するCMPT量の低減の観点から、本実施例に係るヒスタミン分析におけるエキシマー蛍光誘導体化の反応時間を20分に、CMPT濃度を20mMに設定した。
CMPTをDMFに溶解して溶液を作製し、この溶液を室温で保存した後、この溶液を用いてヒスタミンを蛍光誘導体化した。得られた蛍光誘導体化ヒスタミンをHPLCを用いて分離し、そのエキシマー蛍光の強度を求めた。その結果、エキシマー蛍光強度と保存時間の関係は図5に示すようになった。図5から分かるように、CMPTはDMF溶液の状態でも40日以上、ヒスタミンとの反応性が低下せず、蛍光誘導体化することができた。このことから、CMPTは従来のエキシマー蛍光誘導体化試薬に比べると、溶液状態での保存安定性に優れることが分かる。
醤油に含まれるアミン類をLC-MS/MSで分析する場合、アミン類とその他の成分(塩分、有機酸、タンパク質、メラノイジン、アミノ酸等)を分離する前処理が必要である。この前処理法として、非特許文献4に記載された方法が知られている。この方法では、醤油(20μL)に0.1Mの硫酸マグネシウム(20μL)、1M の水酸化ナトリウム(20μL、pH10)、及びアセトニトリル320μLを添加し、遠心処理によりアミン類を含むアセトニトリル層とそれ以外の成分を含む水層に分離する(図6(a)参照)。硫酸マグネシウムはタンパク質等の塩析のために、水酸化ナトリウムはpHを調整して分子型のヒスタミン量を増やすために添加される。本発明者は、この前処理法を参考に、ヒスタミンをCMPTで蛍光誘導体化する場合に適した前処理条件を検討した。
具体的には、濃度が既知のヒスタミンを含む試料をアセトニトリル層と水層に分離したときに該アセトニトリル層に回収されたヒスタミンの割合(回収率(%))を、水酸化ナトリウムの濃度を1~4Mに変化させたとき(図6(b)、非加熱のアセトニトリルと加熱したアセトニトリルを用いたとき(図6(c))の両方について調べた。
