preparation example Construction
[0045] a, preparation of test solution
[0046] Weigh Xiaoerfeike granules, grind them finely, weigh 1-3g, accurately weigh, put in a stoppered Erlenmeyer flask, accurately add 20-50ml of methanol, weigh, ultrasonically treat for 20-40 minutes, let cool, and then Weigh the weight, make up the lost weight with methanol, shake well, filter, and take the filtrate to obtain the test solution;
[0047] b. Preparation of reference substance solution
[0048] Weigh the reference substances of rutin, liquiritin, hesperidin, quercetin, chrysophanol, and emodin methyl ether respectively, weigh them accurately, use methanol as the solvent, prepare mixed reference substance solutions with different mass concentrations, pass through the microporous filter membrane, take the continued filtrate as the reference substance solution;
[0049] c. Determination
[0050] Precisely draw 5-15 μl each of the reference substance solution and the test solution, inject it into a high-performance liqu...
