Embodiment 1
[0032] Take a sample of Auranthus nudiflora and pulverize it, pass through a 40-mesh sieve, accurately weigh 0.5 g of the sample powder, 7 parts in total, place them in conical flasks with stoppers, add pure water, 20% methanol aqueous solution, 40% methanol aqueous solution, 50% methanol water solution, 60% methanol water solution, 80% methanol water solution, 25mL of pure methanol, weighed, ultrasonicated for 45min, allowed to cool to 100%, and the corresponding solvent was used to make up for weight loss, shake well, pass through a 0.22μm microporous membrane, and take the continuation The filtrate was used as the test solution. Using Agilent 1200Infinity high resolution fast liquid chromatography; Agilent Eclipse Plus-C 18 The RRHD column has an outer diameter of 2.1 mm×column length of 150 mm, and a packing diameter of 1.8 μm. The mobile phase is (A) 0.1% aqueous formic acid and (B) acetonitrile, and the gradient elution is as follows:

Embodiment 2
[0037] Take a sample of Nadiflora purple pearl and crush it, pass it through a 40-mesh sieve, accurately weigh 0.5g of the sample powder, a total of 6 parts, place them in a stoppered conical flask, add 25mL of 80% methanol aqueous solution, weigh, and weigh the 6 parts of the sample respectively. Sonicate for 15min, 30min, 45min, 60min, 75min, 90min, let cool, make up for the weight loss with 80% methanol, shake well, pass through a 0.22μm microporous membrane, and take the subsequent filtrate as the test solution. Using Agilent 1200Infinity high resolution fast liquid chromatography; Agilent Eclipse Plus-C 18 The RRHD column has an outer diameter of 2.1 mm×column length of 150 mm, and a packing diameter of 1.8 μm. The mobile phase is (A) 0.1% aqueous formic acid and (B) acetonitrile, and the gradient elution is as follows:
