[Test Example 1]
About the solids of each fraction (the samples corresponding to the solids of fractions 1 to 4 are sampled 1 to 4, respectively) obtained by performing the above-described ion exchange column fractionation in the same manner on a 10-fold scale. The mutagenicity-inhibiting action of was tested and evaluated using the reverse mutation test method (Ames test method). That is, each of the samples 1 to 4 is dissolved in sterilized water, and the final concentration is 1, 2, 5 in terms of the equivalent amount of Agaricus sputum supernatant (amount converted to the supernatant fraction in consideration of the yield of each sample). Or each solution was prepared so that it might become 10 mg / mL, and 0.1 mL of each was dispensed to the test tube. Next, 0.1 mL of a solution in which NDMA is dissolved in dimethylsulfonic acid amide as a mutagen is added, and S9mix (rat liver S9, which contains a drug metabolizing enzyme because NDMA is a mutagen that requires metabolic activation. 0.4 mol / L magnesium chloride aqueous solution, 1.65 mol / L potassium chloride aqueous solution, 1.0 mol / L glucose-6-phosphate aqueous solution, 0.1 mol / L reduced nicotinamide adenine dinucleotide phosphate aqueous solution and 0.2 mol / L mixed solution of sodium phosphate buffer, 0.5 mL of pH 7.4) and 0.1 mL of culture solution of Salmonella typhimurium TA-100 strain were added to prepare a mixed solution.

前記混合溶液を37℃にて20分間振とうした後、軟寒天液2mLを加え、エイムス・プレート(1LあたりD−グルコース20g、寒天15g、Vogel−Bonner培地100mL、ヒスチジン0.62mg及びビオチン0.98mgを含む)にまき、37℃で48時間インキュベートし、該プレート上に出現した復帰突然変異コロニー数を計測した。各試料による変異原物質の変異原性抑制率は、変異発生率(%)=(変異原物質及び試料添加時の変異数−自然発生変異数)/(変異原物質添加時の変異数−自然発生変異数)×100の計算式から求めた数値を比較することにより評価した。ここに、自然発生変異数とは試料のみを添加したときに発生する変異コロニー数である。これらの試験結果の一部を表1に示す。表1において、試料添加量は各試料の収率から換算して上清画分の添加量(2.0mg/plate)に相当する量を用い、変異発生率の数値はNDMAが0.2mmolのみの場合(対照試験)を100としたときの相対値である。又、同条件下で、試料3について、その添加量を変化させた場合の試験結果を表2に示す。   After shaking the mixed solution at 37 ° C. for 20 minutes, 2 mL of soft agar solution was added, and Ames plate (20 g of D-glucose, 15 g of agar, 100 mL of Vogel-Bonner medium, 0.62 mg of histidine and 0. 98 mg), and incubated at 37 ° C. for 48 hours, and the number of back-mutated colonies that appeared on the plate was counted. Mutagenicity suppression rate of mutagen by each sample is: Mutation rate (%) = (Number of mutations when mutagen and sample are added-Number of spontaneous mutations) / (Number of mutations when mutagen is added-Natural The number of mutations generated) was evaluated by comparing the numerical values obtained from the formula of 100. Here, the number of spontaneous mutations is the number of mutant colonies generated when only the sample is added. Some of these test results are shown in Table 1. In Table 1, the amount of sample added is equivalent to the added amount of the supernatant fraction (2.0 mg / plate) in terms of the yield of each sample, and the numerical value of mutation occurrence is only 0.2 mmol for NDMA. In this case, the relative value is 100 (control test). Table 2 shows the test results when the addition amount of sample 3 was changed under the same conditions.

表1のデータから、NDMAによる変異発生率は試料3すなわち両性電解質含有画分を添加したときに顕著に抑制され、これ以外の分画試料では該効果が認められないことが確認された。又、表2から、試料3は濃度依存的にNDMAの変異活性を阻害することも確認した。   From the data in Table 1, it was confirmed that the mutation rate due to NDMA was remarkably suppressed when Sample 3, that is, the amphoteric electrolyte-containing fraction, was added, and the effect was not observed in other fraction samples. From Table 2, it was also confirmed that Sample 3 inhibited the NDMA mutation activity in a concentration-dependent manner.

This fraction 3 consisted of two types of peak components on the HPLC chart.

そこで、前記の試料3のフラクション3について、溶離液を0.5%ギ酸及び5%メタノールにおきかえることを除いて同条件下で前記HPLC分画処理に供し、6種類のフラクション(fr1〜fr6)を分取した。各々を凍結乾燥した後、試験例1と同様に試験してNDMA変異原性抑制作用を評価した結果、表4に示すように、第3番目に溶出したフラクション3(試料3の分画物Fr3のHPLC分画物fr3)を添加した場合に最も強力な効果を発現した。なお、このフラクション3はHPLCチャート上では単一ピーク成分からなるものであった。   Therefore, the fraction 3 of the sample 3 was subjected to the HPLC fractionation under the same conditions except that the eluent was replaced with 0.5% formic acid and 5% methanol, and six types of fractions (fr1 to fr6) were used. Was sorted. After freeze-drying each, the test was conducted in the same manner as in Test Example 1 and the NDMA mutagenicity inhibitory action was evaluated. As shown in Table 4, the third eluted fraction 3 (fraction Fr3 of sample 3) When the HPLC fraction fr3) was added, the strongest effect was exhibited. This fraction 3 was composed of a single peak component on the HPLC chart.

The molecular weight of the fraction consisting of the single peak (HPLC fraction fr3 of the fraction Fr3 of the sample 3) is analyzed using a high performance liquid chromatography / tandem mass spectrometer (LC / MS / MS). The ion peaks at m / z 124 and 138 were detected.
Apparatus: AP13000LC / MS / MS system manufactured by Applied Biosystems, eluent: 1 mM ammonium formate / methanol (20/80), flow rate: 0.2 mL / min, ionization method: electrospray ionization method, positive ion mode.

However, in this test method, since MNNG is a direct mutagen that does not require metabolic activation, the addition of S9mix was omitted. A part of the results is shown in Table 5. In Table 5, the amount of sample added is equivalent to the amount of supernatant fraction added (1.0 mg / plate) in terms of the yield of each sample. It is a relative value when (control test) is 100. Table 6 shows the test results when the addition amount of Sample 1 was changed under the same conditions.
