Abstract

The invention discloses an extraction method and an application of a component group of a traditional Chinese medicine extract for treating hemorrhagic stroke. The extraction method comprises the following steps: after crushing rheum officinale, cortex moutan, red peony roots, dried radix rehmanniae and pseudo-ginseng in a certain weight ratio, adding water to decoct and extract; after extracting an extraction liquid by using dichloromethane, extracting a water layer by using n-butyl alcohol; and recovering and drying the n-butyl alcohol extraction liquid to obtain the component group of the traditional Chinese medicine extract. Analyzed by HPLC-MS, the traditional Chinese medicine extract is prepared from 33 components: paeoniflorins, tannins, paeonosides, anthraquinones, stilbenes, saponins and iridoid glycosides and can be used for remarkably reducing levels of neuronspecific enolase of essential hypertension male rats, S-100beta proteins, IL-1, TNF-alpha and plasma fibrinogen and can be used for preparing the medicine for treating hemorrhagic stroke.

Description

[0001] 1. Technical field [0002] The invention relates to the technical field of traditional Chinese medicine, in particular to a method for extracting component groups of Chinese medicine extracts for treating hemorrhagic stroke and its application. [0003] 2. Background technology [0004] Hemorrhagic stroke (cerebral hemorrhage) is a common clinical disease at home and abroad. The disease has sudden onset, rapid progress, and high fatality rate. The prognosis of patients directly affects the quality of life after the disease. Neuron-specific enolase (SNE) and S-100β protein are important indicators for judging the severity of brain damage. Among them, SNE is a marker enzyme of neurons and neuroendocrine cells. When ischemia and hypoxia occur in brain tissue, Elevated levels of SNE in cerebrospinal fluid. S-100β protein is a brain-specific protein, and the higher the level of S-100β protein in serum, the more severe the brain damage. The current Western medicine treatmen...
