Embodiment 1

[0020] Extraction of components:

[0021] 1000 g of Panax notoginseng medicinal materials are crushed into coarse powder, 2.5 times the amount of 90% ethanol is added, and the mixture is heated to reflux for extraction, and concentrated under reduced pressure until it has no alcohol taste. Dilute with water to 0.25g (crude medicine) / ml, stand for 24 hours, and filter. The filtrate was passed through a macroporous adsorption resin column, followed by gradient elution with 20%, 40%, 60%, 80% and 90% (volume ratio) ethanol, and collected in 500 ml portions. The eluent was analyzed by silica gel H thin-layer chromatography, the developing solvent was "n-butanol-ethyl acetate-water" 5:0.5:4 (upper layer), and the color was developed by a 10% (volume ratio) sulfuric acid ethanol solution. Combine the same components of the chromatographic spots and recover the solvent under reduced pressure. Then apply the chromatography silica gel column, and eluted with the solvents of "chloroform-...

Embodiment 2

[0031] The extraction of the components is the same as in Example 1.

[0032] Weigh the following components (same as above): ginsenoside Rg1 30g, ginsenoside Rb1 28.5g, ginsenoside Re3.0g, ginsenoside Rd 7.5g and notoginsenoside R1 7.8g.

[0033] The preparation method is as follows: mix the above-mentioned components, dissolve in an appropriate amount with water for injection, add needles to decolorize with activated carbon, filter, add water for injection to the total amount, adjust pH to 6.7, filter, freeze-dry, and get ready.

Embodiment 3

[0035] Weigh the following components: ginsenoside Rg1 45g, ginsenoside Rb1 29g, and ginsenoside Re 2.5g.

[0036] The preparation method is as follows: mix the above-mentioned components, dissolve in proper amount with water for injection, add needle to decolor with activated carbon, filter, add water for injection to the total amount, adjust pH to 6.0, filter, freeze-dry, and get ready.

Abstract

The invention relates to a pharmaceutical composition and a preparation method thereof. The pharmaceutical composition contains ginsenoside Rg1, ginsenoside Rb1 and ginsenoside Re, wherein the weight ratio of ginsenoside Rg1: ginsenoside Rb1: ginsenoside Re is 1:0.7:1.2. The composition provided by the invention has notable effects and high safety, can alleviate apoplexy symptoms, obviously shortens the course of disease, improves depression of patients with apoplexy sequelae, and the like.

Description

Technical field [0001] The present invention relates to the field of medicine, in particular to a medicinal composition for treating hemorrhagic stroke or schizophrenia residual period. Background technique [0002] Stroke is a group of diseases whose main clinical manifestations are cerebral ischemia and hemorrhagic injury. It is also known as stroke or cerebrovascular accident. Stroke is a rapid onset, with a very high mortality and disability rate. According to a report by the World Health Organization, deaths due to stroke are the second highest death rate in the world, second only to cancer, and about 1 in the number of deaths per year. 4 people died of a stroke. There are more than 10 types of cancer. If the mortality rate of a single type is considered, stroke can be ranked first. In the United States, the mortality rate of first stroke patients is about 7%, and the mortality rate in my country is even higher. [0003] Stroke is also the primary cause of adult disability....
