Embodiment Construction

[0005] Identification: Take 5 tablets of this product, remove the film coat, grind finely, take 1g of powder, add 40ml of 80% ethanol, ultrasonically treat for 40 minutes, filter, evaporate the filtrate to dryness, add 10ml of water to dissolve the residue, filter, add water to the filtrate to saturate Extract with n-butanol twice (10ml each time), combine the extracts, evaporate to dryness, add 2ml of ethanol to the residue to dissolve, and use it as the supply solution. Take another isorhamnetin-3-O-neohesperidin reference substance, add ethanol to make a solution containing 1mg per 1ml, as the reference substance solution. According to the test of thin-layer chromatography (Appendix VIB, Chinese Pharmacopoeia 2005 Edition), draw 5 μl of each of the above two solutions, and spot them on the same silica gel GF respectively. 254 On a thin-layer plate, develop with ethyl acetate-butanone-formic acid-water (5:3:1:1) developer, take it out, dry it, and inspect it under a UV lamp ...
