Embodiment 1
[0052] Embodiment 1 high performance liquid chromatography condition optimization
[0053] 1 Selection of extraction method
[0054] The extraction solvents were 70% ethanol, 50% methanol, 70% methanol, pure methanol, etc.; the sample weight was 0.25g, 0.50g, 1.0g; the solvent volume was 25mL, 50mL, 100mL; the ultrasonic treatment time was 30min, 60min, 90min. The preferred extraction method is: accurately weigh 0.50 g of the test product powder, add 50 mL of 50% methanol solution, and ultrasonically treat for 60 min. At this time, the peak area of the chromatogram is the best.
[0055] 2 Selection of column temperature
[0056] This study investigated the peak elution time and content determination accuracy of each component under the same chromatographic conditions and different column temperatures. 25°C, 30°C, and 35°C were investigated respectively. It was found that at 30°C, the separation of each chromatographic peak reached the standard, and the The peak time is app...

Embodiment 3
[0141] Example 3 Polygonum Polygoni Multiflori TLC Identification in Shouhui Tongbian Capsules
[0142] A. Preparation of the test solution: Take 4g of the contents of Shouhui Laxative Capsules from batch 200201, grind them finely, add 30ml of 50% methanol for the first time, extract by heating and reflux for 30min, add 24ml of 50% methanol for the second time, extract by heating and reflux After 30 minutes, combine the two extracts, centrifuge, take the supernatant, extract 3 times with 60 mL of ether, 20 mL each time, collect the ether layer, combine the extracts, evaporate to dryness, add 2 mL of methanol to dissolve the residue, and use it as the test solution.
[0143] B. Preparation of reference medicinal material solution: take 0.5 g of Radix Polygoni Multiflori as the reference medicinal material, and prepare the reference medicinal material solution in the same way; Emodin methyl ether and emodin reference substances were accurately weighed, dissolved in methanol to p...
