Abstract

The invention discloses a technology for qualitatively identifying an exogenous mixture II (which is prepared by extracting medicinal materials such as schefflera octophylla bark, evodia lepta, roughhaired holly and helicteres angustifolia through a scientific method) by adopting a thin-layer chromatography identification method. The method belongs to the technical field of medicines and comprises the steps of preparation of a reference solution, preparation of a test solution, chromatographic conditions and the like. According to the method disclosed by the invention, qualitative identification is carried out on the exogenous mixture II by adopting the thin-layer chromatography identification method and material established by the invention, and the method is high in specificity and good in stability and can be used for quality control of an exogenous mixture II product.

Description

technical field [0001] The invention belongs to a quality control method of Waigan No. 2 mixture (which is prepared by scientifically extracting and preparing medical materials such as duck foot veneer, trichaku, ganglion and mountain sesame). Background technique [0002] Influenza is a clinically common disease. Traditional Chinese medicine, as a traditional medical technology in my country, has conducted in-depth research on the syndrome differentiation and treatment of colds since ancient times. According to the theoretical analysis of traditional Chinese medicine, a cold is caused by the invasion of the human body by the six evils and viruses. Among them, wind evil is the first of the six evils, which is the main cause of colds. Because there are different levels of pathogenicity, different strengths of righteousness, and differences in the four seasons and six qi, the symptoms are also slightly different. According to the difference of pulse syndrome and tongue synd...
