Embodiment 1

[0018] Take 20 grams of Echinacea plant powder as raw material, place it in a round-bottomed flask, add 10 times (ie 200ml) 30% ethanol solution (add quantitative enzyme inhibitor), place on a water bath, reflux and extract at 55℃ After 2 hours, the filtrate and residue were collected after filtration. Then add 10 times the 30% ethanol solution to the residue, reflux and extract for 2 hours under the same conditions, then filter, and combine the two filtrates. Place the filtrate at 4°C for 24 hours, then filter to remove the precipitate, and then pass through a 0.45um microporous membrane to remove bacteria and macromolecular proteins. The filtrate from which the protein has been removed is placed on a rotary evaporator, concentrated by rotary evaporation at 50°C, and concentrated until thick and strong, and then evaporated to a paste in a water bath at 70°C. Finally, the concentrated extract is placed in a vacuum drying oven and dried under vacuum at 50-60°C. The brown solid extr...

Embodiment 2

[0020] Take 20 grams of Echinacea plant powder as raw material, place it in a round-bottomed flask, add 15 times (ie 300ml) 40% ethanol solution, place it on a water bath, reflux and extract at 70℃ for 4 hours, filter and collect the filtrate and Residue. Then add 15 times the 40% ethanol solution to the residue, reflux and extract for 4 hours under the same conditions, then filter, and combine the two filtrates. Place the filtrate at 4°C for 24 hours, then filter to remove the precipitate, and then pass through a 0.45um microporous membrane to remove bacteria and macromolecular proteins.

Finally, the concentrated extract is placed in a vacuum drying oven and dried under vacuum at 50-60°C. The brown solid extract can be obtained. The extract is dissolved, a...

Embodiment 3

[0022] Take 20 grams of Echinacea plant powder as raw material, place it in a round bottom flask, add 15 times (ie 300ml) 80% ethanol solution, place it on a water bath, reflux for 2 hours at 55℃, collect the filtrate and Residue. Then add 15 times the 80% ethanol solution to the residue, reflux and extract for 2 hours under the same conditions, then filter, and combine the two filtrates. Place the filtrate at 4°C for 24h, then filter to remove the precipitate, and then pass through a 0.45um microporous membrane to remove bacteria and macromolecular proteins. The filtrate from which the protein has been removed is placed on a rotary evaporator, concentrated by rotary evaporation at 50°C, and concentrated until thick and strong, and then evaporated to a paste in a water bath at 70°C. Finally, the concentrated extract is placed in a vacuum drying oven and dried under vacuum at 50-60°C. The brown solid extract can be obtained. The extract is dissolved, and the analysis result of high...

Abstract

The technological process of extracting Echinacea purpurea includes ethanol reflux extraction, membrane filtering to eliminate impurities, concentration, vacuum drying, column chromatography and other steps. During the extraction, a kind of enzyme is used to suppress the decomposition of the effective components in the extractive and to raise the content of the effective components. The extractive has relatively high bioactivity and contains rich polysaccharide and general phenol compounds. The extractive has the functions of raising immunity, resisting virus, treating common cold, etc. The chicoric acid as one extractive may be used as a kind of standard matter.

Description

Technical field: [0001] The invention relates to a process for extracting and preparing effective medicinal ingredients from Echinacea plants. Background technique: [0002] Echinacea is a plant of the genus Echinacea in the Asteraceae family, native to the United States. Its extract has the effects of improving human immunity, anti-virus, and curing colds. It is a traditional American herbal medicine. In recent years, as a herbal medicine, echinacea has become the most popular immunomodulatory drug in the European and American markets. However, there is very little research on echinacea in my country, and there is no related patent. [0003] In my country, there have been a few reports on the determination of the chemical components and the pharmaceutical characteristics of Echinacea purpurea in recent years, but there are no reports on the extraction process of Echinacea purpurea extract. Summary of the invention: [0004] The purpose of the present invention is to extract use...
