Description
Technical field
The present invention relates to a kind of nuezhenoside, Radix seu Folium Tosicodendri Delavayi glucoside compositions and preparation medicinal usage thereof.
Background technology
Influenza virus is serious day by day at present; And influenza virus and respiratory tract disease and the systemic disease that causes are closely related; China is one of influenza country occurred frequently, and is not only populous, and living habit also helps the relay of influenza virus; The number of times of falling ill for each person every year reaches 0.3～0.7 time not to be waited, and key population reaches 2～4 times.There is serious threat in influenza to the mankind, New Development kind influenza virus especially, and it not only causes other infected by microbes of Secondary cases, and can directly cause organ to destroy and the allergy causing death.But the method and the treatment means that do not have efficacious therapy influenza virus and disease (influenza) thereof at present as carry out the inflammatory reaction treatment to clinical symptoms, are cured the symptoms, not the disease.The method of present modal prevention and treatment influenza virus is to use influenza virus vaccine inoculation, non-specific anti virus herb or Western medicine oseltamivir phosphate (oseltamivir phosphate capsule)-neuraminidase inhibitor.Yet influenza virus vaccine prophylactic immunization drawback is that the inoculation crowd is selective, is not that everybody can inoculate.In addition, the influenza virus vaccine protective rate is not high, and guard time is also lacked (3～6 months).Though most of non-specific anti virus herbs lay claim to antivirus action at present, be not to influenza virus, and antivirus action mechanism are unclear.At many kind treatment affection of exogenous wind-cold of our former studies, the Chinese prescription of the flu that doctor trained in Western medicine is thought does not have the effect of direct resisiting influenza virus.Briefly, the Chinese prescription of not every treatment flu all has the effect of clear and definite inhibition influenza virus.Western medicine " oseltamivir phosphate (oseltamivir phosphate capsule; (3R; 4R, 5S)-amino-3 (1-third the 2-ethoxyethyl acetate)-1-cyclohexene-1 carboxylic acid, ethyl ester phosphate of 4-acetamide-5-) " be neuraminidase inhibitor, influenza virus is got into cell has specific inhibitory effect; But not only cost an arm and a leg, and have that some patients take that the back vomiting occurs, feels sick, side reactions such as insomnia, headache, stomachache, diarrhoea, dizziness, fatigue, nasal obstruction, pharyngalgia and cough.Oseltamivir phosphate capsule is that the esterase that is positioned at liver and intestinal in vivo is converted into active metabolite and plays the neuraminidase effect that suppresses, and also will influence its drug effect if patient's liver and intestinal organ dysfunction are undesired.In addition, the renal insufficiency patient also wants careful usefulness.
Traditional Chinese medicine is recognized leaf of Turpinia pomifera (Roxb) D O. and is had heat-clearing and toxic substances removing, relieving sore throat and diminishing swelling, promoting blood circulation and stopping pain.Be used for the tonsillitis sore throat, laryngopharynx swelling and pain, sore swollen toxin falls and pounces on the pain of injury.Nuezhenoside and Radix seu Folium Tosicodendri Delavayi glucoside are one of main components of leaf of Turpinia pomifera (Roxb) D O..The Fructus Ligustri Lucidi function is a nourishing the liver and kidney, and black hair makes eye bright.Be mainly used in vertigo and tinnitus; Soreness of the waist and knees, early whitening of beard and hair, poor vision; Be used to treat chronic tracheitis, hepatitis, hyperlipidemia, diabetes, climacteric syndrome, infertility, atherosclerosis etc. in recent years, nuezhenoside is one of main component of Fructus Ligustri Lucidi more.Exocarpium Citri Grandis has cold expelling, dampness, promoting the circulation of QI, expectorant.Be used for the cough due to wind and cold, the itching of the throat abundant expectoration, food stagnation is got sick from drinking too much wine, and the vomiting and nausea painful abdominal mass is vexed.Radix seu Folium Tosicodendri Delavayi glucoside is one of main component of Exocarpium Citri Grandis.But do not find that leaf of Turpinia pomifera (Roxb) D O. and contained nuezhenoside and Radix seu Folium Tosicodendri Delavayi glucoside, Fructus Ligustri Lucidi and contained nuezhenoside, Exocarpium Citri Grandis and contained Radix seu Folium Tosicodendri Delavayi glucoside thereof thereof thereof have the effect that suppresses influenza infection, duplicates, and do not find that it has the effect that suppresses neuraminidase yet.
