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...

Abstract

The invention discloses a detection method of traditional Chinese medicine preparations. The detection method is used for detecting active ingredient content of f traditional Chinese medicine preparations, ensuring that medicine quality accords with drug standards, and ensuring stability of curative effect of the traditional Chinese medicine preparations. The detection method comprises following steps: TLC is adopted for qualitative identification of radix achyranthis bidentatae, radix salviae miltiorrhizae, fructus gardenia, herba epimedii, and semen cassia in the traditional Chinese medicine preparations, and HPLC is adopted for detection of contents of salvianolic acid B and gastrodin in the traditional Chinese medicine preparations.

Description

technical field [0001] The invention relates to a detection method of a traditional Chinese medicine preparation, which belongs to the technical field of traditional Chinese medicine. Background technique [0002] Danxi Granules are composed of 12 traditional Chinese medicines such as Danshen, Achyranthes bidentata, Gastrodia elata, and Moutan cortex. Traditional medicine believes that it has the effects of nourishing yin and calming the liver, extinguishing the wind and dredging the collaterals, clearing away heat and irritability, and is used for the syndrome of blood stasis in the meridians and collaterals during the recovery period of stroke and kidney deficiency. Numbness, dizziness, soreness of the waist and knees, etc., the effect is better. At present, the quality control standard of this preparation is not perfect, and some identification operations are cumbersome, so it is impossible to qualitatively and quantitatively detect the active ingredients of traditional ...
