Embodiment 1
[0036] A method for identifying the traditional Chinese medicine Xuezhining Pills, which uses thin-layer chromatography to identify anthraquinone active ingredients in Xuezhining Pills and Nuciferine in Xuezhining Pills. The identification of anthraquinone active ingredients in Xuezhining Pills includes the following step:
[0037] (1) Preparation of the test solution: take 5g of the traditional Chinese medicine Xuezhining Pills, cut into pieces, add 20ml of methanol, ultrasonically treat for 30 minutes, filter, evaporate the filtrate to dryness, add 5ml of water to the residue to dissolve, add 0.5ml of hydrochloric acid, and heat to reflux After 30 minutes, let it cool, shake and extract twice with diethyl ether, 10ml each time, combine the diethyl ether solution, evaporate to dryness, add 0.5ml of chloroform to the residue to dissolve, and obtain the test solution;
[0038] (2) Preparation of reference substance solution: take chrysophanol and chrysophanin reference substanc...
Embodiment 2
[0046] A method for identifying the traditional Chinese medicine Xuezhining Pills, which uses thin-layer chromatography to identify the anthraquinone active ingredients in the Xuezhining Pills, including the following steps:
[0047] (1) Preparation of the test solution: take 10g of the traditional Chinese medicine Xuezhining pills, cut them into pieces, add 50ml of methanol, ultrasonically treat for 30 minutes, filter, evaporate the filtrate to dryness, add 30ml of water to the residue to dissolve, add 5ml of hydrochloric acid, and heat to reflux for 30 minutes Minutes, let cool, shake and extract 2 times with diethyl ether, 30ml each time, combine the diethyl ether solution, evaporate to dryness, add 5ml of chloroform to the residue to dissolve, and obtain the test solution;
[0048] (2) Preparation of reference substance solution: get chrysophanol, emodin methyl ether reference substance, add chloroform to make a mixed solution containing 5 mg chrysophanol and emodin methyl ...
Embodiment 3
[0051] A kind of identification method of traditional Chinese medicine Xuezhining Pills, its identification adopts thin-layer chromatography to comprise the following steps in the Nuciferine in Xuezhining Pills:
[0052] (1) Preparation of the test solution: take 20 g of the traditional Chinese medicine Xuezhining pills, cut them into small pieces, add 35 ml of methanol, ultrasonically treat them for 30 minutes, filter, evaporate the filtrate to dryness, add 20 ml of ammonia test solution to the residue to dissolve, and vibrate with chloroform Shake and extract 3 times, 20ml each time, combine the chloroform solution, evaporate to dryness, dissolve the residue with 15ml of 0.01mol / L hydrochloric acid solution, add 20ml chloroform and shake for extraction, discard the chloroform solution, and use the acid water solution Adjust the pH value of the concentrated ammonia solution to 9.5, then shake and extract twice with chloroform, 20ml each time, combine the chloroform solution, e...
