Description

A kind of Herba Sarcandrae chewable tablet and preparation method thereof
Technical field
The present invention relates to a kind of chewable tablet and preparation method thereof, be specifically related to a kind of Herba Sarcandrae chewable tablet and preparation method thereof, belong to medical art,
Background technology
Herba Sarcandrae, another name Herba Pileae Scriptae, Herba Pileae Scriptae, Herba Pileae Scriptae, synthetism lotus, anti-swollen No. I etc., be the dry Herb of Chloranthaceae plant plait Corallium Japonicum Kishinouye Sarcandra glabra (Thunb.) Nakai.Leaf is containing coumarone, lactone, flavone, phenols, cyanogen glycoside, volatile oil and Bulbus Allii tannic acid; Fruit is containing pelargonidin Fructus rhamni (Rhamnus davurica Pall.) glucose.Main component is volatile oil (having linalyl acetate etc. in oil), succinic acid, Fumaric acid, coumarone, flavonoid glycoside, lactone, tannic acid etc.
Herba Sarcandrae has dispelling wind and removing obstruction in the collateral, blood circulation promoting and blood stasis dispelling function, and has antibacterial, antiinflammation, has heat-clearing and toxic substances removing, effect of dispersing swelling and dissipating binds, belongs to hyperactivity of toxic heat patient for pneumonia, appendicitis, cellulitis, and can be used for assistant treating cancer.
Herba Sarcandrae has following pharmacological action:
Antibacterial and anti-inflammation functions, Herba Sarcandrae has broad-spectrum antibacterial action, is wherein extremely quick to staphylococcus aureus, dysentery bacterium I, to golden Portugal persister, Boydii dysentery bacterium C-2 type, Bacillus typhi H 901, paratyphoid fever A type is Gao Min, also has certain effect to bacterium flexneri III type, escherichia coli, bacillus pyocyaneus.Fumaric acid quick paramount quick inhibitory action in having first streptococcus, micrococcus catarrhalis, streptococcus, hemophilus influenza, Diplococcus pneumoniae in Herba Sarcandrae.Herba Sarcandrae is to rat paw inflammation caused by the not Mus auricle inflammation caused by Oleum Tiglii, carrageenin and mice cotton balls internal bud is swollen significant inhibitory action.In addition, the growth of stomachache caused by acetic acid and anti-bacteria can also obviously be alleviated.
Antitumaous effect, Herba Sarcandrae extract and total volatile oil have obvious anti-S 180and W 256the effect of tumor strain, wherein mouse peritoneal injection crude extract 0.25g/kg, to S 180suppression ratio be 42% ~ 49.4% (P < 0.001), to rat W 256suppression ratio be 39.0% (P < 0.01), lumbar injection volatile oil component linalyl acetate 1mg/kg, to S 180suppression ratio be 45.3% (P < 0.001).Herba Sarcandrae total flavones has inhibitory action to ribonucleic acid in ehrlich ascites cell (RNA) and DNA (deoxyribonucleic acid) (DNA) content.
Herba Sarcandrae clinically with other drug matching, for antitumor, antiinflammatory, treatment acute upper respiratory tract infection, treatment thrombocytopenia, treatment digestive system disease, treatment oral disease, treatment psoriasis etc., all obtain satisfied curative effect, but because the traditional extraction process level of understanding limit, not yet scientific research is goed deep into extraction process, its curative effect does not reach optimization, and therefore patent medicine effect is general separately, in Clinical practice, do not have advantage.
Domestic existing Herba Sarcandrae chewable tablet has ZHONGJIEFENG ZHUSHEYE, Zhongjiefeng Capsules and ZHONGJIEFENG PIAN.Herba Sarcandrae blade of having gone on the market weighs 500 ~ 750mg, and flap-type is unfavorable for greatly swallowing, and especially brings larger misery for laryngopharynx swelling and pain patient consumes.
Summary of the invention
The present invention improves on the basis of ZHONGJIEFENG PIAN, object is the problem solving the great dysphagia of current Herba Sarcandrae blade, improve medicine mouthfeel, change existing extraction and formulation method and technique simultaneously and owe science, at utmost can not play the problem of Herba Sarcandrae drug effect, there is provided that a kind of taking convenience, mouthfeel are good, toxic and side effects is little, drug effect improved, onset rapidly, be conducive to the Herba Sarcandrae chewable tablet that curative effect of medication plays, and provide its preparation method.
For solving the problem, technical scheme of the present invention is:
