Embodiment 1

[0025] A method for checking the limit of strychnine in Huatuo Zaizao Pills uses thin-layer chromatography to measure the limit of strychnine, comprising the steps of:

[0026] Preparation of the test solution: take Huatuozaizao pills, grind them, weigh 16g of powder, then add 50ml of chloroform, 5ml of ethanol, 6ml of ammonia water, ultrasonically treat for 30-60min; filter, evaporate the filtrate to dryness, add 6% of the residue HNO 3 Heat 20ml of the solution on a water bath to dissolve, adjust the pH value to 11-12 with ammonia water, shake and extract 3 times with chloroform, 20ml each time, combine the extraction solutions, evaporate to dryness, add 1ml of chloroform to the residue to dissolve, As the test solution.

[0027] Reference substance solution preparation: take strychnine reference substance, add chloroform to make a solution containing 2mg per 1ml, as the reference substance solution.

[0028] Limit inspection: draw 12 μl of the test solution and 10 μl of t...

Embodiment 2

[0032] The characteristics of this embodiment are: the difference is that in the preparation step of the test solution: the residue is added with 6% H 2 SO 4 The solution was heated to dissolve. Other specific operation steps are the same as embodiment 1.

Embodiment 3

[0034] The characteristics of this embodiment are: the difference is that in the preparation step of the test solution: use 5% NaHCO 3 Adjust the pH value; in the limit check step: use toluene-acetone-ethanol-concentrated ammonia test solution (volume ratio 5:5:0.6:0.4) as the developing agent. Other specific operation steps are the same as embodiment 1.

Abstract

The invention discloses a limited inspection method for strychnine in Huatuo reconstituted pills, comprising: 1) taking Huatuo reconstituted pills, weighing the powder, adding extraction solvent, ethanol, ammonia water, ultrasonic treatment; filtering, evaporating the filtrate to dryness, Add acid solution to the residue, heat to dissolve, adjust pH value, shake and extract with organic solvent, evaporate to dryness, add chloroform to dissolve the residue, and use it as the test solution; 2) take strychnine reference substance, add chloroform Make a solution as the reference substance solution; 3) draw the test solution and the reference substance solution, respectively point on the same silica gel G thin-layer plate, develop with a developing agent, take it out, dry it, spray it with a chromogenic agent, and use it for testing. In the chromatogram of the reference substance, there should be no spots at the position corresponding to the chromatogram of the reference substance, or the spots should be smaller than those of the reference substance. The invention can well control the quality of Huatuo Zaizao Pills, ensure the stable, uniform and controllable quality of the pills, and ensure the effectiveness and safety of human medicine.
