Test example 2: method for simultaneously quantitatively determining multi-index medicinal components of open throat sword spray
When various sample solutions are measured in the above test example 1, it was found that after the sample solutions are injected into the liquid chromatograph, the column pressure at the initial test is usually between 80 and 90bar, however, the column pressure gradually increases after the test sample solutions are injected a plurality of times, for example, the column pressure increases between 120 and 130bar after the test sample solutions are injected 5 times, the column pressure increases between 150 and 160bar after the test sample solutions are injected 10 times, the column pressure increases between 210 and 220bar after the test sample solutions are injected 15 times, and the column pressure further increases are unacceptable; the column pressure can be returned to the original state by backflushing the column with mobile phase a/mobile phase b=10/90 ratio mobile phase for 2 hours, but this operation is not preferable in large sample size analytical tests; it has been found that this increase in column pressure does not occur when testing the control solution, indicating that this increase in column pressure is caused by the relevant components in the test solution. The inventors tried to use other brands of C18 columns (column length, column inner diameter and packing particle size are the same), namely three of Supelcoc C18, agilent C18, waters C18 columns, and as a result of the test according to test example 1, it was also found that there was an unacceptable increase in column pressure as the test proceeded, for example, three columns were increased in column pressure between 202 to 210bar, 185 to 192bar, 205 to 212bar, respectively, after injection of 12 test sample solutions. The inventors tried to add 1.2% isopropyl alcohol and 0.2% ammonium chloride simultaneously to both mobile phase a, acetonitrile and mobile phase B, 0.1% formic acid solution, so that both additives were contained in a and B at the same concentration, and still eluted according to the gradient elution procedure of test example 1, keeping the other operating conditions unchanged, and as a result, it was revealed that the initial column pressure was maintained between 80 and 90bar when the test sample solution and other solutions were tested, the column pressure was maintained between 85 and 95bar after 30 times or more of testing each solution, for example, the column pressure was maintained between 92 and 97bar when the test sample solution was injected for 30 times. Further, the present inventors tried to add 1.2% isopropyl alcohol to both mobile phase a, acetonitrile and mobile phase B, 0.1% formic acid solution, so that both a and B contained the same concentration of the additive, and still eluted according to the gradient elution procedure of test example 1, keeping other operating conditions unchanged, and as a result, it was revealed that the initial column pressure was still gradually increased between 80 and 90bar when the test sample solution and other solutions were tested, for example, the column pressure was increased between 109 and 115bar after the injection of 5 test sample solutions, and between 133 and 140bar after the injection of 10 test sample solutions, and between 160 and 168bar after the injection of 15 test sample solutions. Further, the present inventors tried to add 0.2% ammonium chloride to both mobile phase a, acetonitrile and mobile phase B, 0.1% formic acid solution, so that both a and B contained the same concentration of the additive, and still eluted according to the gradient elution procedure of test example 1, keeping other operating conditions unchanged, and as a result, it was revealed that the initial column pressure was still gradually increased between 80 and 90bar when the test sample solution and other solutions were tested, for example, the column pressure was increased between 115 and 122bar after the injection of 5 test sample solutions, and between 140 and 150bar after the injection of 10 test sample solutions, and between 180 and 190bar after the injection of 15 test sample solutions. From this, it is known that the simultaneous addition of both isopropanol and ammonium chloride in the mobile phase can avoid the problem of increased column pressure when testing the sample solution.
For this reason, in this test example 2, except that 1.2% isopropyl alcohol and 0.2% ammonium chloride were simultaneously added to both the mobile phase a, acetonitrile and the mobile phase B, i.e., 0.1% formic acid solution, the other operating conditions were all carried out with reference to test example 1, various test solutions were still prepared using test example 1, the results of various tests were substantially the same as those of test example 1, and typical results were as follows: 1) Retention time: matrine t is about 9.1min, bergenin t is about 19.1min, and pterocarpin t is about 46.5min, substantially unchanged; 2) Linear regression equation: matrine y=21238x-44.457 and R 2 Bergenin y=27577x+86.624 and r=0.9999 2 =0.9997, pterosiny= 93253x-34.145 and R 2 =0.9998; 3) KHJ20190127 precision of test article: matrine peak area mean= 1380561 and rsd=0.25%, bergenin peak area mean= 2924216 and rsd=0.22%, sanguinarine peak area mean= 607144 and rsd=0.35%; 4) 24h stability test of KHJ20190127 test article: matrine peak area mean= 1380268 and rsd=0.33%, bergenin peak area mean= 2923523 and rsd=0.41%, sanguinarine peak area mean= 604327 and rsd=0.38%; 5) Repeatability test of KHJ20190127 test article: matrine peak area mean= 1372084 and rsd=0.51%, bergenin peak area mean= 2908473 and rsd=0.43%, sanguinarine peak area mean= 602836 and rsd=0.62%; 6) Sample recovery rate test of KHJ20190127 test article: the average recovery of three concentrations of matrine was 99.64% and rsd=1.33%, and the average recovery of three concentrations of bergenin was 101.46% and rsd=1.26%, the average recovery of three concentrations of pterosin from trefoil is 101.84% and rsd=1.64%; 7) The contents (mug/ml) of matrine, bergenin and pterocarpin in 5 batches of open throat sword spray are measured simultaneously, and the result is that: three component contents of KHJ20190127 were 324.4. Mu.g/ml, 530.9. Mu.g/ml, 32.3. Mu.g/ml, KHJ20190610 were 332.2. Mu.g/ml, 525.6. Mu.g/ml, 32.6. Mu.g/ml, KHJ20190816 were 326.7. Mu.g/ml, 535.5. Mu.g/ml, 32.5. Mu.g/ml, 329.4. Mu.g/ml, 531.4.

Mu.g/ml, and 3.3. Mu.g/ml, respectively.
