Description
Technical field
The invention belongs to natural plants chemical field is and in particular to a kind of extraction of muercai (vegetable) and its new application.
Background technology
Herba basellae rubrae, another name bean curd dish, kermes dish, because of the approximate Auricularia of its leaf, plump and glutinous cunning, therefore named Herba basellae rubrae.Wood
A kind of ancient vegetable of Er Caishi China, is distributed widely in China's most area.China's traditional Chinese medical science shows, Herba basellae rubrae has cunning
Intestinal, removing pathogenic heat from blood and toxic substance from the body, connect muscle symplectic bone, detumescence the effects such as, be usually used in treat breast intestinal accumulated heat gloomy, oliguria is puckery, dysentery, have blood in stool, speckle
The diseases such as rash, treatment skin ulcer, burn and scald, traumatic injury, rheumatic arthritis.Modern pharmacological research shows, Herba basellae rubrae have antiviral,
The pharmacologically active such as antioxidation and anti-inflammation.Herba basellae rubrae is nutritious, containing multiple chemical compositions, mainly includes saponin, waves
Hair oil, polysaccharide and various vitamin.We consult lot of documents and find, put down in anti-hepatitis virus and dog blood vessel with regard to Herba basellae rubrae
Sliding muscle cell multiplication inhibitory activity aspect there are no relevant report, and therefore, the present invention chooses Herba basellae rubrae and carries out above-mentioned activity research
There is wide DEVELOPMENT PROSPECT.
It is known that Chinese herbal medicine resource is national strategy resource, it is the basis of China's Chinese medicine sustainable development.Ten
After eight is big, China has successively worked out " Chinese medicine developmental strategy planning outline (2016-2030) " and " Chinese crude drug protection and development
Planning (2015-2020) ", the modernization of Chinese medicine is the grand strategy target of China, is also the emphasis neck of the current new drug development of China
Domain.The present invention chooses the plant Herba basellae rubrae of medicine-food two-purpose as object of study, using modern technologies, Herba basellae rubrae is extracted
Separate and obtain a kind of extract, and to this extract in terms of anti-hepatitis virus and inhibition against proliferation of dog vascular smooth muscle cells
Carry out systematic study, be that China develops treatment hepatitis B from Herba basellae rubrae and atherosclerosis drug has established important theoretical base
Plinth.
Content of the invention
In order to overcome the shortcomings of background technology presence, the present invention provides a kind of preparation of extraction of muercai (vegetable) and its new use
