Description
Technical field
The present invention relates to the processing and utilization field of radix tetrastigme, and in particular to one kind is obtained using medicine fungi fermentation radix tetrastigme is eaten
Composition and preparation method thereof.
Background technology
Radix tetrastigme (Tetrastigma hemsleyanum Diels et Gilg) is Vitaceae Tetrastigma plant, not
Name:Gold thread hoist, stone mouse, hemsley rockvine root, category Rhamnales, Vitaceae herbaceous species.Scientific name:Tetratigma hemsleyanum, it is Zhejiang, good fortune
The regional tradition such as build and commonly use green herbal medicine, it is best with the medicinal effects of underground root tuber and fruit.Treated with radix tetrastigme Zhejiang is among the people
Tumour is more remote, and radix tetrastigme is region medicinal material, extremely rare, be distributed in Zhejiang, Jiangxi, Fujian, Anhui, Guangdong, Guangxi,
The ground such as Yunnan, radix tetrastigme has the function that radiating, qi-regulating, promoting blood circulation, tonifying spleen, removing toxic substances, wind-dispelling, anti-inflammatory, among the people to be used for treating children
High fever, pharyngo-laryngitis chronica, tonsillitis, hepatitis, pneumonia, gastritis, scrofula and snake bite etc. have special effect.Modern pharmacological research
Show that radix tetrastigme has anti-inflammatory, analgesia and antipyretic, antitumor, the antiviral, effect such as regulation is immune.
At present, the active component in radix tetrastigme is obtained using traditional extracting and developing method more, such as Chinese patent
The Chinese medicine radix tetrastigme for being used to prevent and treat tumour disclosed in ZL200510050649.5, it is original using by radix tetrastigme
The water and/or alcohol extracting thing of material make active component.Overcritical dioxy disclosed in Chinese patent application CN201110264176.4
Change the method for carbon extraction radix tetrastigme general flavone, by radix tetrastigme pulverizing medicinal materials 60-80 mesh, add supercritical carbon dioxide extracting tank,
Liquid carbon dioxide and entrainer are passed through, under the conditions of pressure 20-30MPa, 40-50 DEG C of temperature, extracts 2-3 hours, separator
Middle decompression parsing extract, reclaim reagent, dry radix tetrastigme general flavone.Chinese patent ZL200810120750.7 discloses one
The technique of kind high efficiency extraction flavone compound from radix tetrastigme, its technological process are:Raw material radix tetrastigme, air-dry, shred, add
Water extracts in ultrasonic extractor, extract solution is concentrated into certain volume, then carry out adsorption bleaching with activated carbon.Followed by
Cavitation suspension extraction separator, is first extracted with ethyl acetate, and reclaims ethyl acetate, aqueous solution part is extracted with chloroform, returns
Chloroform is received, by aqueous solution partial concentration to without organic reagent taste, by macroporous absorbent resin, is washed successively with water and 50% ethanol
It is de-, 50% ethanol eluate is collected, recycling design obtains Lemna paucicostata to doing.
Containing the nutritional ingredient such as polysaccharide, flavones, polyphenol isoreactivity composition and starch, protein in radix tetrastigme, traditional carries
Take, separate in its active component technique, starch, protein, stimulating component etc. extract together into branch, add in separation
Processing step, cause the active component content in final products it is relatively low, activity it is relatively low.
The content of the invention
The invention provides a kind of using the composition for eating the acquisition of medicine fungi fermentation radix tetrastigme, active component in said composition
Content and activity it is high, there is good hypolipemic function.
Present invention also offers a kind of preparation method using the composition for eating the acquisition of medicine fungi fermentation radix tetrastigme, using true
Bacterium fermentation radix tetrastigme, is favorably improved the content and activity of active component in final products, obtains the hair with hypolipemic function
Ferment composition.
It is a discovery of the invention that according to radix tetrastigme nutritional ingredient and active ingredient feature, pass through the specific fungi fermentation of the present invention
And specific technique, and the bletilla striata is added into culture medium, effectively the nutritional ingredient in radix tetrastigme and active ingredient can be entered
Row is biodegradable and utilizes, effectively the stimulating component in radix tetrastigme is removed and converted, and radix tetrastigme resource is obtained fully
Utilization, be favorably improved the content and activity of active component in final products.
The technical solution adopted by the present invention is:
A kind of preparation method using the composition for eating the acquisition of medicine fungi fermentation radix tetrastigme, including step:
(1) take the mushroom Agaricus blazei Murill after activation to be inoculated into liquid MRS culture mediums and cultivate -8 days 2 days, be collected by centrifugation the

To streptomycete seed liquor;
(3) the Brazilian mushroom liquid seeds liquid of step (1) is accessed in radix tetrastigme solid-state fermentation culture medium, at 18 DEG C -30
DEG C culture -20 days 2 days, be subsequently placed in alternating magnetic field environment and be further cultured for -30 days 5 days, cultured products are through vacuum freeze drying, powder
Radix tetrastigme product by solid-state fermentation is obtained after broken;Contain radix tetrastigme and the bletilla striata in the radix tetrastigme solid-state fermentation culture medium;
(4) the radix tetrastigme product by solid-state fermentation of step (3) is obtained into the subcritical extraction of radix tetrastigme fermentation through Subcritical Water Extraction
Thing I is taken, remaining residue obtains extracting residue II after vacuum freeze drying after extraction.
(5) by the streptomycete seed liquor access streptomycete liquid fermentation medium of step (2), cultivated at 20 DEG C -30 DEG C
10h-120h, centrifugation, obtains streptomycete fermentation product III;Contain extraction residue in the streptomycete liquid fermentation medium
Ⅱ;
The composition that the acquisition of medicine fungi fermentation radix tetrastigme is eaten in the utilization is radix tetrastigme fermentation subcritical abstraction thing I and strepto-
Bacterium tunning III.
When the present invention carries out radix tetrastigme solid state fermentation, directly using through at the step incubation of liquid MRS culture mediums two containing cholate
The Brazilian mushroom liquid seeds liquid of reason, and the bletilla striata is added into culture medium, can effectively by the nutritional ingredient in radix tetrastigme and
Active ingredient is carried out biodegradable and utilized, effectively the stimulating component in radix tetrastigme is removed and converted, and is favorably improved
The content and activity of active component in final products.In step (4) and step (5), radix tetrastigme product by solid-state fermentation is carried out sub-
Critical extracts, and enables that the activity of active ingredient in extract at utmost retains, content is greatly improved;Again will extraction
The culture medium main as streptomycete liquid fermentation of residue afterwards, and be incubated using through the step of liquid MRS culture mediums two containing NaCl
The streptomycete seed liquor of processing, is recycled by integration, radix tetrastigme resource is fully utilized, is further increased
The content and activity of active component in final products.
In order to reach more preferable effect, preferably:
