Abstract

The invention provides a quality control method of amygdalin in children lung heat cough and asthma granules. A thin-layer chromatography identification method has the advantages of small sample application amount, good separation effect, clear spots, moderate specific shift value and good reproducibility. Quantitative analysis is carried out on the amygdalin component in the infantile lung-heat cough and asthma granules through content determination, it is verified that the content of the amygdalin in the infantile lung-heat cough and asthma granules can be accurately and efficiently detected through content determination chromatographic conditions, and through combination of a thin-layer chromatography identification method and content, the content of amygdalin in the children lung heat cough and asthma granules can be effectively controlled, and the medication safety of the children lung heat cough and asthma granules is ensured.

Description

technical field [0001] The invention relates to the field of amygdalin detection, in particular to a method for quality control of amygdalin in Xiaoerfeirekechuan granules. Background technique [0002] Bitter almonds are the dried and mature seeds of the Rosaceae plant Apricot apricot, Siberia apricot, Northeast apricot or apricot. Bitter in nature and flavor, tepor, slightly poisonous; returns lung, large intestine meridian. It has the effects of reducing qi, relieving cough and asthma, moistening the intestines and laxative, and is mostly used for cough and asthma, full chest phlegm, intestinal dryness and constipation. [0003] Amygdalin is a common cyanogenic glycoside and an active ingredient in the traditional Chinese medicine bitter almond. So far, it has become a commonly used expectorant and antitussive agent in medicine, as well as an auxiliary anticancer drug. In addition to amygdalin, bitter almonds generally contain β-glucosidase. Laetrile can generate gluco...
