Technical field
The invention belongs to Chinese medicines to extract field, more specifically more particularly to a kind of extraction side of Radix Angelicae Sinensis effective component
Method.
Background technique
Angelica herbaceos perennial, is distributed mainly on the country of more rain and more cold air, is treatment coronary heart disease, cerebral thrombosis, branch gas
Guan Yan, the diseases such as feelings asthma clinical application, volatile oil is mainly to use ingredient in Radix Angelicae Sinensis medicinal material, have absorb it is fast, anti-
The good feature of oxidisability.Steam distillation extraction method is a kind of relatively conventional Angelica oil extracting method, have it is easy to operate, at
This low advantage.But when using steam distillation to extract Radix Angelicae Sinensis, more by-product, such as aqua aromatica can be generated.Virtue
Containing a large amount of water-soluble volatile oil in perfume, but since the stability of aqua aromatica is preferable, so being not readily separated, thus passing
In the technique of system, aqua aromatica all does waste treatment, causes the waste of resource.We need a kind of more environmentally-friendly Radix Angelicae Sinensis thus
Extracting method solves the above problems.
Summary of the invention
The purpose of the present invention is to provide a kind of extracting methods of Radix Angelicae Sinensis effective component, to solve to mention in above-mentioned background technique
Out the problem of.
To achieve the above object, the invention provides the following technical scheme:
A kind of extracting method of Radix Angelicae Sinensis effective component, includes the following steps:
S1, raw material preliminary treatment: taking the Radix Angelicae Sinensis of life in 2 years or more, after screening and cleaning, is carried out by slicer to Radix Angelicae Sinensis
Then slicing treatment carries out drying and processing to Radix Angelicae Sinensis by dryer, drying temperature is 40-45 DEG C, when the water content of Radix Angelicae Sinensis
Stop drying less than 12%；
S2, raw material crush: the Radix Angelicae Sinensis Tabellae after drying being put into pulverizer and is crushed, to obtain Radix Angelicae Sinensis powder；
S3, distillation: Radix Angelicae Sinensis powder is put into reaction kettle, adds water to impregnate at normal temperature 1.5 hours, saturated sodium-chloride is then added
Aqueous solution is impregnated, and soaking time is 1-2 hours, is then sent in distillation still and is distilled, temperature 100-110
DEG C, distillation time is 3-5 hours, to obtain distillate；
S4, component separation: distillate is put into separator, and top section is volatile oil, and underclad portion is aqua aromatica, when
After component separation, it is stored respectively；
S5, extraction: sending distillate into extractor and be added extractant, in 0.8-1.5Mpa, the environment that temperature is 40-50 DEG C
The lower extraction for carrying out 1-2 hours by a definite date, extraction after the completion of semi-finished product can be obtained, by centrifuge to semi-finished product carry out separation and
Filtering, to obtain Angelica oil；
S6, aqua aromatica recycling: Static Adsorption is carried out to aqua aromatica by activated-charcoal column, then activated-charcoal column is carried out by ether
Desorption, can be completed the recycling of the Angelica oil in aqua aromatica.
Preferably, in the step S1, Radix Angelicae Sinensis after carrying out slicing treatment with a thickness of 0.5-1cm.
Preferably, the specification of the Radix Angelicae Sinensis powder is 30-50 mesh.
Preferably, ratio of water to material is 10:1 in the step S3.
Compared with prior art, the beneficial effects of the present invention are: the present invention before it is distilled, first pass through water to Radix Angelicae Sinensis powder into
Row impregnates, and is then infiltrated, is extracted to Radix Angelicae Sinensis by sodium chloride, to improve the extraction of Radix Angelicae Sinensis volatile oil in distillation
Rate；Aqua aromatica is separated by way of activated carbon adsorption, is then desorbed by ether, it is easy to operate, and
Cost is lower.Compared with traditional Radix Angelicae Sinensis extracting mode, the present invention is increased and is worked as by the recycling to waste aqua aromatica
The recovery rate for returning volatile oil reduces the waste of resource.
Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, below in conjunction with specific embodiment, to this
Invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, not
For limiting the present invention.
A kind of extracting method of Radix Angelicae Sinensis effective component, includes the following steps:
