Embodiment 1
[0151] Danknee granule batch number: 20131111
[0152] 1. Identification
[0153] A. TLC identification of Achyranthes bidentata: Take 20g of Danxi granules, grind finely, add 50mL of ethanol, heat and reflux for 1 hour, filter, evaporate the filtrate to dryness, add 15mL of water to dissolve, shake and extract 3 times with n-butanol saturated with water , 15 mL each time, combined n-butanol solution, washed 3 times with n-butanol-saturated water, 15 ml each time, combined water washing solution, and set aside. Evaporate the n-butanol solution to dryness, add 5 mL of ethanol to the residue to dissolve, add a neutral alumina column (100-200 mesh, 10 g, 1.5 cm in diameter), first elute with 40 mL of ethyl acetate, and use ethyl acetate for later use; Elute with 30ml of ethanol, collect the eluent, evaporate to dryness, add 1ml of methanol to the residue to dissolve, and use it as the test solution. Take another ecdysterone reference substance, add methanol to make a solution c...
