Embodiment 1
[0076] Preparation of the test solution: take Linaoxin tablets (batch number 1), remove the film coating, grind, and pass through a 100-mesh sieve. Weigh about 1.0g, accurately weigh, accurately pipette 25mL of dilute ethanol, add it into a stoppered Erlenmeyer flask, and weigh. Ultrasound for 30min (power 250W, frequency 40kHz). Take it out, put it at room temperature, weigh it, make up for the weight loss, shake it well, filter it, and take the filtrate to pass through a 0.45μm filter membrane to obtain the final product.
[0077] Preparation of the reference substance solution: Accurately weigh about 10 mg of the stilbene glycoside reference substance, place it in a 25mL volumetric flask, add dilute ethanol to dissolve, set the volume to the mark, and shake well to obtain the reference substance mother solution with a concentration of 0.4059mg / mL .
[0078] Inject 10 μL of samples precisely, record the peak area, and calculate the content of stilbene glycosides. The resul...
