[0023] (1) Preparation of the test solution: accurately weigh an appropriate amount of Evodia rutaecarpa Asarum preparation, and accurately add 20-100 times the amount of methanol-water (w / v), the volume ratio of methanol-water is 8:2-10, Accurately weigh the weight, 30 ~ 50KHz, 100 ~ 300W ultrasonic treatment for 10 ~ 60min, methanol - water to make up the lost weight, filter through a 0.45μm microporous membrane, and take the subsequent filtrate to obtain the test solution (the subsequent filtrate is Analysis of commonly used terms, in order to discard the initial part of the filtrate, take the latter part of the filtrate. The initial part of the filtrate may be absorbed by the filter material, which is not accurate enough);
[0024] (2) Preparation of reference substance solution: Precisely weigh an appropriate amount of evodiamine, evodiamine, and limonin reference substances, dissolve them in methanol and constant volume, and prepare them to contain 50-150ug / ml evodiamine ...
Embodiment 1
[0039] This implementation case shows a fingerprint construction method of Evodia rutaecarpa Asarum preparation according to the following steps:
[0040] 1. Preparation of the test solution
[0041]Accurately weigh 0.5 g of Evodia rutaecarpa Asarum preparation, add 25 mL of methanol-water (volume ratio 8:2), accurately weigh, ultrasonically treat for 30 minutes (250W, 45KHz), and use methanol-water (volume ratio 8:2) to supplement the Lost weight, shake well, filter through a 0.45 μm microporous membrane, and take the subsequent filtrate to obtain the test solution.
[0042] 2. Preparation of reference solution
[0043] Accurately weigh the appropriate amount of evodiamine, evodiamine, and limonin reference substances, dissolve them in methanol and constant volume, and prepare them respectively as controls containing 80ug / ml evodiamine, 50ug / ml evodiamine, and 100ug / ml limonin. product solution.

[0059] This implementation case shows a fingerprint construction method of Evodia rutaecarpa Asarum preparation according to the following steps:
[0060] 1. Preparation of sample solution to be tested
[0061] Accurately weigh 0.5g of Evodia rutaecarpa Asarum preparation (S11), add 50ml of methanol-water (8:2) accurately, accurately weigh the weight, ultrasonically treat for 15min (35KHz, 300W), add methanol-water (8:2) to make up The lost weight was filtered through a 0.45 μm microporous membrane, and the filtrate was taken to obtain the sample solution to be tested.
[0062] 2. Preparation of reference solution
[0063] Accurately weigh the appropriate amount of evodiamine, evodiamine, and limonin reference substances, dissolve them in methanol and make up to volume, and prepare a mixed reference substance containing 50ug / ml evodiamine, 30ug / ml evodiamine, and 150ug / ml limonin solution, namely the reference solution.
