Embodiment 1
[0039] The present embodiment provides a kind of assay method of Flos Chrysanthemi UPLC fingerprint, comprises the steps:
[0040] (1) Preparation of the test solution: take the wild chrysanthemum medicinal material, crush it through a 60-mesh sieve, take about 0.5g of the sample powder, weigh it accurately, place it in a 100mL conical flask, add 50mL of methanol, weigh it, and use an ultrasonic power of 160W , frequency 59kHz, 30min, cooling and replenishing, filtering through a 0.22μm microporous membrane, taking the subsequent filtrate to obtain the test solution;
[0041] (2) Preparation of the reference solution: Accurately weigh the appropriate amount of chlorogenic acid, luteolin, luteolin and mongoside, dissolve it in 75% methanol solution and set the volume to 100mL, and obtain concentrations of 0.0598, 0.1129, 0.0565 and 0.1965 μg / μL reference substance single solution, respectively accurately draw 10mL of each reference substance solution and put it in a 50mL volume...
