Description
Technical field
The invention belongs to effective ingredients in plant extractive technique field, and in particular to a kind of monoterpenes compound and its preparation side
Method and application.
Background technology
Inflammation is body the stimulation of various pro-inflammatory cytokines and damage are produced it is a kind of main non-specific to defend to be adapted to
Property immune response.The pathogenic process of many diseases all with inflammation-related, clinically common rheumatoid, arthritis, asthma, wound
Wound, burn, septic shock, heart failure etc. have inflammatory mediator（Cell factor）Participation.Anti-inflammatory drug can block inflammation
The generation or release of medium, suppress inflammatory reaction, so as to treat the medicine of the disease relevant with inflammatory mediator.Current pin both at home and abroad
Treatment to active chronic inflammation is main based on antibiotics, although the treatment of these medicines can receive good effect,
But because of being continuously increased for antibody-resistant bacterium, there is increasing case although with antibiotic therapy, the state of an illness but cannot be controlled effectively,
And it is of common occurrence that antibiotic produces the case of side effect in clinical practice.Caused by the virus infection of segmental inflammation disease system,
Antibiotic is substantially invalid.In recent years, sight is gradually turned to aboundresources, pure natural Chinese herbal medicine, nationality by China and foreign countries researcher
Medicine, it is desirable to therefrom find new anti-inflammatory drug.Sinalbin, forulic acid, rattletop are found that from Chinese herbal medicine, ethnic drug at present
A series of natural anti-inflammatory drugs such as glycosides, quercitin, kuh-seng alkaloid, rheum emodin, decanoy acetaldehyde, celastrin.These crude drugs
The good anti-inflammatory activity that thing is shown increasingly proves that it is a very promising direction that anti-inflammatory drug is screened from natural products.
Chenopodium ambrosiodies (Chenopodium ambrosioides L.) is Chenopodiaceae (Chenopodiaceae) genus Chenopodium, not
Goose pin is careless for name, red Herba Lycopi, stinkweed, hookworm grass, lousewort etc., be Yi nationality, distributed over Yunnan, Sichuan and Guizhou's common drug among the people.All herbal medicine, there is wind-dispelling, dehumidifying,
Desinsection, antipruritic, the effect of stimulating the menstrual flow, relieve pain, for treat skin arthralgia pain due to rheumatism, hookworm, roundworm, dysmenorrhoea, amenorrhoea, skin eczema and
The diseases such as snake bite and insect sting.China's genus Chenopodium has 19 kinds of original seeds and 2 subspecies, is distributed mainly on salt-soda soil and dry area in north china.
The genus Chenopodium chemical composition is mainly containing type compounds such as volatile oil, sesquiterpene, steroidal, flavones, saponin(es.At present to native chaste tree
