Embodiment 1
[0048] This example compares the quality control products and standard products for monitoring 78 kinds of neuropsychiatric drugs when prepared from different serum matrices. The specific preparation method is as follows:
[0049] 1) Accurately weigh 15 kinds of antiepileptic drugs, 23 kinds of antipsychotic drugs, and 40 kinds of antidepressant drugs, and use methanol to dissolve, and obtain each drug standard mother liquor of the concentration shown in Table 1.
[0050] 2) Pipette the volume of each drug standard stock solution in Table 1 and mix it with 55 μL of 50% methanol aqueous solution to obtain a mixed standard solution 1 containing all drugs, wherein the concentration of each drug is shown in Table 1.
[0051] 3) Mix 20 μL of mixed standard solution 1 with 980 μL of 50% methanol aqueous solution to obtain mixed standard solution 2, in which the drug concentrations are shown in Table 1.

Embodiment 2
[0078] This example provides a quality control product for monitoring 78 kinds of neuropsychiatric drugs at the same time. The specific preparation method is as follows: according to the method in Example 1, the middle concentration quality control standard solution is horse serum according to the volume of 5%: 90% The ratio is mixed, and the mixed solution containing antioxidants and preservatives is added according to 5% volume ratio, wherein the different antioxidant groups used are shown in Table 5, and the preservatives used are thimerosal with a concentration of 0.002g / ml. volume 100ml) and then freeze-drying (the specific conditions used for freeze-drying are: pre-freezing temperature is set to -50°C, duration 300min; primary drying temperature is set to -30°C, duration is 1200min, and pressure is maintained at 0.2mbar; analytical drying temperature is set to -30 ℃, the duration is 360 min, and the pressure is maintained at 0.3 mbar) to obtain the corresponding quality c...
Embodiment 3
[0090] The present embodiment provides a method for simultaneously monitoring 78 neuropsychiatric drugs, comprising the following steps:
[0091] 1) Using the same method as in Example 2 and adding the antioxidant group 3 in Table 5 as antioxidants, the low-concentration quality control product L (prepared by using the low-concentration quality control mixed standard solution in Example 1) was prepared respectively, Medium-concentration quality control substance M (prepared by using the medium-concentration quality control mixed standard solution in Example 1), and high-concentration quality control substance H (prepared by using the high-concentration quality control mixed standard solution in Example 1).
[0092] 2) Mix the mixed standard solution 1 and mixed standard solution 2 prepared in Example 1 with horse serum in a volume ratio of 5%:90%, respectively, and add to the antioxidant group in Example 2 in a volume ratio of 5%. 3 Mix with the mixed solution of the preservat...
