Description
Technical field
The present invention relates to extract sealwort in effective ingredient field, specially a kind of extracting method of Rhizoma Polygonati extract and
Extraction element and with antiviral and help the animal feed of growth.
Background technology
Sealwort nature and flavor are sweet, eat tasty and refreshing, and its meat root-like stock is plump, containing much starch, sugar, fat, protein,
Carrotene, vitamin and various other nutritional ingredients.Sealwort can be eaten raw, can also stew clothes, and long-term consumption can make us strength times
Increase, muscle is full, marrow is strong, highly beneficial to body.
Wherein, plurality of active ingredients, the important effective ingredient Siberian solomonseal rhizome polysaccharide of such as one of which are contained in sealwort.Sealwort is more
Sugar has the advantages that hypoglycemic, clearing heat and detoxicating and element culturing fixed folder.Therefore, how from sealwort it is quicker, simpler with
It is a urgent problem to be solved and yield higher extracts Siberian solomonseal rhizome polysaccharide.
In the extraction of traditional Siberian solomonseal rhizome polysaccharide, the general polysaccharide nutriment extracted using water extract method in sealwort,
However, only with water extract method, the yield of Siberian solomonseal rhizome polysaccharide is very low, substantial amounts of Huang is still contained in the sealwort residue by extraction
Smart polysaccharide, is wasted very serious.
Also, in leaching process, typically Solomonseal Rhizome is placed in the container containing solvent, ultrasonic extraction is subsequently placed into
Device carries out ultrasonic extraction so that Siberian solomonseal rhizome polysaccharide is separated out, however, existing ultrasonic extraction device is general without agitating device, positioned at appearance
The polygonatum rhizome granular extraction effect of device middle part is poor, is unfavorable for the Siberian solomonseal rhizome polysaccharide inside polygonatum rhizome granular and separates out completely.
The content of the invention
The invention provides a kind of extracting method of Rhizoma Polygonati extract, there is the extracting method simple to operate, sealwort to extract
The high advantage of thing yield.
To achieve the above object, the present invention provides following technical scheme:
A kind of extracting method of Rhizoma Polygonati extract, comprises the following steps：
(1) it will clean, the sealwort rhizome of drying is ground to powdered, 70~80 mesh sieves excessively, obtains Solomonseal Rhizome；
(2) Solomonseal Rhizome is filtered with 90 DEG C~100 DEG C pure 60~80min of flooding, filtrate concentration is concentrated
Liquid A, filter residue A；
(3) dried in the environment of filter residue A being placed in into 40~50 DEG C, obtain filter residue B；
(4) in filter residue B, the volume ratio added with filter residue B is 5:1 ethanol solution, the quality of the ethanol solution is dense
Spend for 80%~95%, extract 20~30min, filtering, filtrate concentration obtains concentrate B；
(5) concentrate A and concentrate B is merged, is concentrated into medicinal extract shape, obtains the Rhizoma Polygonati extract.
Wherein, the Rhizoma Polygonati extract in sealwort is first extracted using water extract method, the most of polysaccharide contained in sealwort can be made
Separate out, after the completion of extraction, leaching operation is carried out to the polysaccharide in filter residue using ethanol solution again so that the polysaccharide material in sealwort
Matter yield is higher.
Above-mentioned steps are more specific to be, using vacuum distillation concentration in step (5).Vacuum distillation can reduce whole extraction
The time that technique is spent.
Obtained Rhizoma Polygonati extract is extracted present invention also offers a kind of said extracted method.The Rhizoma Polygonati extract of the present invention
In, contain Siberian solomonseal rhizome polysaccharide and other active ingredients.
The present invention also provides a kind of extraction element of above-mentioned Rhizoma Polygonati extract, including for loading solvent and openend upward
Liquid storage tank and load Solomonseal Rhizome column shape container, liquid storage tank side wall provided with discharge internal liquid delivery port, institute
State liquid storage tank and the fixed mount for being used for fixing column shape container is provided with provided with inwall, the hollow bulb of column shape container is also arranged in including sliding
The plug of position and the operation shank for being easy to staff to exert a force, the plug are fixedly connected with operation shank；

Rhizoma Polygonati extract mentioned in 2~embodiment of embodiment 4,6~embodiment of embodiment 7, its preparation method and sheet
The extracting method that embodiment is provided is identical.
Test case 1
Experiment is randomly divided into 8 with small piglet 80 as taking Zhejiang A ＆ F University's animal medicine president gesture, body weight homogeneous
Group, numbering is A~H, by feed that 2~embodiment of embodiment 8 provided respectively antiviral of the small piglet of A~G groups and helps growth
Animal feed and pure water, two times a day, the animal food-contg fed every time is：Only, the feeding volume of pure water is 250g/：1L/
My god；To the quality such as the small piglet feed of H groups and the small piglet of A~G groups pure water and wait the normal diet of quality；Persistently feed A
Statistics such as following table after~G groups and the small piglet surrounding of H groups, four weeks：
Table 1：The small piglet weight statistical form of A~F groups
| Group/weight | Before experiment (kg) | After experiment (kg) | Increase weight (kg) | Ill (only) |
| A | 20.10 | 37.00 | 16.90 | 0 |
| B | 20.00 | 39.40 | 19.40 | 0 |
| C | 19.60 | 38.10 | 18.50 | 0 |
| D | 19.40 | 34.10 | 14.70 | 1 |

| G | 19.80 | 32.10 | 12.30 | 2 |
| H | 20.00 | 30.30 | 10.30 | 6 |
As shown in Table 1, in the piggy that A~C groups have fed the present invention, the weightening of B groups piglet is most, and increase weight 19.4kg, says
The animal feed that bright embodiment 2 is provided is optimal to the growth-promoting effect of piglet；
Simultaneously as the animal feed that embodiment 5 is provided does not add Rhizoma Polygonati extract so that the weightening of D group piglets
Significantly lower than A~C groups of addition Rhizoma Polygonati extract, therefore Rhizoma Polygonati extract serves key work to the growth for promoting piglet
With；
From the piglet weightening of E~G groups significantly lower than B groups (E~G groups are B comparative example), Radix Isatidis and radix tetrastigme exist
There is synergistic function with Rhizoma Polygonati extract in the feed that the present invention is provided so that the feed to the growth-promoting effect of piglet more
It is good.
From A~C and the ill piglet quantity of E~G groups, Radix Isatidis and three is added in feed provided by the present invention
Ye Qingke increase piglets suffer from the probability of infectious disease；
From F groups and the ill piglet quantity of G groups, radix tetrastigme is added in feed to the anti-communicable disease effect of piglet more
It is good；
From A~C and the ill piglet quantity of D groups, Rhizoma Polygonati extract is ill to prevention piglet also to have effect well
Really, and with radix tetrastigme, Radix Isatidis there is good compatibility, so that the animal feed that the present invention is provided is while also have anti-
The effect of virus.
Although the present invention is described in detail with reference to the foregoing embodiments, for a person skilled in the art,
It can still modify to the technical scheme described in foregoing embodiments, or to which part technical characteristic progress etc.
With replacing, within the spirit and principles of the invention, any modifications, equivalent substitutions and improvements made etc. should be included in this
Within the protection domain of invention.
