Embodiment 1
[0045] Take the same batch of medicinal material powder (Batch S1, Guangdong Zizhu, one year old, produced in Pingxiang Base, collected on 2011.10.21), passed through a 50-mesh sieve, weighed 1.0g accurately, put it in a 25mL volumetric flask, and added 10mL of 50% methanol aqueous solution Weigh it, extract it with ultrasound for 30 minutes (150W, 80Hz), let it cool, weigh it, make up the missing weight with 50% methanol aqueous solution, shake well, and let it stand again. Before use, filter with a 0.22 μm filter membrane, and take the subsequent filtrate as the test solution.
[0046] Using LC-20AD ultra-fast liquid chromatography (UFLC), column Welch Material C 18 Column (2.1mm×100mm, 1.8μm), the mobile phase is acetonitrile (A)-0.5% phosphoric acid aqueous solution (B), and the gradient elution is as follows:
[0047] time (minutes)
Mobile phase (v / v%)
0~10
5~15% mobile phase A and 85~95% mobile phase B
10~20
Linear gradient change to: ...
Embodiment 2
[0066] (1) Take the powder of batches of medicinal materials from S1 to S10, pass through 45 meshes, accurately weigh 1.0g, put it into a 25mL volumetric flask, add 50mL of 70% methanol aqueous solution to weigh it, extract it by ultrasonic for 30 minutes (150W, 80Hz), let it cool , Weigh the weight, make up the missing weight with 70% methanol aqueous solution, shake well, and let stand again. Filter with a 0.22 μm filter membrane before use, and take the subsequent filtrate as the test solution (S1~S10 batches of test solution);
[0067] Using LC-20AD ultra-fast liquid chromatography (UFLC), column Welch Material C 18 Column (2.1mm×100mm, 1.8μm), the mobile phase is acetonitrile (A)-0.5% phosphoric acid aqueous solution (B), and the gradient elution method is as follows:
[0068] time (minutes)
Mobile phase (v / v%)
0~10
8-15% mobile phase A and 85-92% mobile phase B
10~20
Linear gradient change to: 15-17% mobile phase A and 83-85% mobile ph...
Embodiment 3
[0081] (1) Take 16 batches of medicinal material powder (S1-S16), pass through 80 meshes, accurately weigh 1.0g, put in a 25mL volumetric flask, add 10mL of 50% methanol aqueous solution to weigh, and ultrasonically extract for 30 minutes (150W, 80Hz). Let it cool, weigh it, make up the missing weight with 50% methanol aqueous solution, shake well, and let it stand again. Filter with a 0.22 μm filter membrane before use, and take the subsequent filtrate as the test solution (S1~S16 batches of test solution);
[0082] Using LC-20AD ultra-fast liquid chromatography (UFLC), column Welch Material C 18 Column (2.1mm×100mm, 1.8μm), the mobile phase is acetonitrile (A)-0.5% phosphoric acid aqueous solution (B), and the gradient elution is as follows:
[0083] time (minutes)
Mobile phase (v / v%)
0~10
