Problems solved by technology

Due to the high polarity and low content of saponins, it is cumbersome and time-consuming to separate and identify their active components using traditional ultraviolet or evaporative light detectors. Therefore, a sensitive and selective method was established to analyze simultaneously Saponins and flavonoids, very necessary

Abstract

The invention provides a method for determining content of various components in a Chinese medicinal composition freeze-dried injection. The Chinese medicinal freeze-dried injection comprises ginseng and epimedium herb which serve as raw materials and is clinically used for treating amyotrophy and myasthenia gravis which are caused by diseases such as motoneuron diseases (amyotrophic lateral sclerosis, progressive spinal muscular atrophy, progressive bulbar palsy and primary lateral sclerosis), progressive muscular dystrophy, congenital myopathy and the like. In the method, 15 active compounds in the Chinese medicinal freeze-dried injection are qualitatively and quantitatively analyzed simultaneously by a tandem mass spectrometry of a high performance liquid chromatography, and the method can be used for quality control of a product.

Description

technical field [0001] The invention relates to a method for determining the content of active compounds in traditional Chinese medicine freeze-dried injections, 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 content control of effective compounds is very important for the quality control of freeze-dried injections of traditional Chinese medicine. [0003] CN1785223A discloses a medicine for treating muscular atrophy and myasthenia gravis and its preparation method. The patent discloses the prescription, preparation, capsule, tablet and other preparation methods of the medicine; the patent also discloses the pharmacodynamics of the medicine Experiments have confirmed that the drug can enhance the vitality of normal motor neurons, promote the growth of neurites, protect mot...
