Abstract

This invention relates to haw antihyperglycemic slice identification method, which adopts film chromatography spectrum as haw antihyperglycemic slice qualitative identification of simple operations and good isolation and high accuracy and clear spot through negative lighting without interference with operating property belonging to haw antihyperglycemic slice quality standard.

Description

technical field [0001] The invention relates to a quality control method of Hawthorn Essence Jiangzhi Dispersible Tablets, in particular to a method for identifying hawthorn in Hawthorn Essence Jiangzhi Dispersible Tablets. Background technique [0002] The quality control standard of Hawthorn Jingjiangzhi Tablets involved in the standards issued by the Ministry of Health of China does not describe the identification method of its hawthorn TLC. Usually in practice, the method of physical and chemical identification (color reaction and fluorescence reaction) is adopted, specifically: take the sample, grind it finely, add 10ml of 0.1mol / L sodium hydroxide solution, stir, filter, and the filtrate is extracted with n-butanol (10ml, 5ml), combine the n-butanol solution, evaporate to dryness on a water bath, add 2ml of ethanol to the residue to dissolve, then ① take 1ml of the above ethanol solution, evaporate to dryness on a water bath, add 1ml of acetic anhydride to the residue,...
