Embodiment 100
[0074] The method for establishing the fingerprint of Bailemian Capsules in this embodiment comprises the following steps:
[0075] (1) Preparation of the test solution: take 1.0 g of the contents of Bailemian Capsules, weigh them accurately, put them in a stoppered Erlenmeyer flask, add 25 mL of methanol aqueous solution with a volume fraction of 70%, weigh them, and heat to reflux for 30 minutes , let it cool, use a volume fraction of 70% methanol aqueous solution to make up the lost weight, shake well, pass through a 0.45 μm microporous membrane, and take the subsequent filtrate as the test solution;
[0076] (2) Preparation of reference solution: accurately weigh quercitrin reference substance, 2,3,5,4′-tetrahydroxystilbene-2-O-D glucoside reference substance, schisandrol A reference substance, dandelion Phenolic acid B reference substance, emodin reference substance, add volume fraction of 70% methanol aqueous solution to make each 1mL containing 65μg quercitrin, 45μg 2,3...
