Abstract

The invention relates to a novel method for detecting Longdan Xiegan particles and belongs to the field of modernization of Chinese traditional medicine. According to the invention, by establishment of identification and content determination on gentian serving as monarch drug and baical skullcap root serving as ministerial drug and content determination on gardenia, and being matched with original identification on gardenia, ingredients of the medicament and compatibility of the ingredients can be more comprehensively detected; the method for detecting the Longdan Xiegan particles is standardized; and the novel method is helpful to knowing content and stability of the Longdan Xiegan particles and explaining the medicinal material basis of the medicament.

Description

technical field [0001] The invention belongs to the field of traditional Chinese medicine modernization, and in particular relates to a detection method of Longdan Xiegan Granules. Background technique [0002] The composition of traditional Chinese medicine is complex, especially the compound prescription of traditional Chinese medicine often contains many kinds and many kinds of ingredients, forming a very complicated system. At present, the research and development of new effective parts of traditional Chinese medicine preparations and modern compound Chinese medicine preparations are increasing, and new processes and various extraction methods are used in the research and production of medicines. [0003] With the rapid development of modern analysis and testing technology, equipment and instruments, the content determination and chromatographic identification of traditional Chinese medicine have become important means of detection. However, at present, only the content...
