Abstract

The invention provides a method for determining contents of multiple components in a lyophilized injection of a traditional Chinese medicine composition. The raw materials of the traditional Chinese medicine lyophilized injection include ginseng and short-horned epimedium herb. The lyophilized injection is clinically used for treating muscular atrophy and myasthenia gravis caused by motor neuron diseases (amyotrophy lateral sclerosis, progressive spinal myodystrophia, progressive bulbar paralysis and primary lateral sclerosis), progressive muscular dystrophy, congenital myopathy and other diseases. The method provided by the invention adopts a high performance liquid chromatography to conduct fingerprint measurement which is used for qualitative quality control of products.

Description

technical field [0001] The invention relates to a qualitative determination method of a traditional Chinese medicine freeze-dried injection, belonging to the technical field of pharmaceutical preparation analysis. Background technique [0002] In terms of quality standards for freeze-dried injections of traditional Chinese medicine, there are many items that require control. Among them, the qualitative fingerprint is a comprehensive and quantifiable means of identification. It is based on the systematic research on the chemical components of traditional Chinese medicine. Evaluate the authenticity, excellence and stability of the quality of traditional Chinese medicinal materials and semi-finished products of traditional Chinese medicine preparations. "Integrity" and "ambiguity" are its salient features. At present, the fingerprint technology of traditional Chinese medicine has involved many methods, including thin layer scanning (TLCS), high performance liquid chromatograph...
