Abstract
The present invention relates to a kind of extracting methods of Shell of Water Chestnut active ingredient, are crushed after collecting fresh unmetamorphosed Shell of Water Chestnut cleaning first, and then it is uniformly mixed with ethyl alcohol and heating stirring extraction, the preceding activated carbon that adds in of filtering are adsorbed, filtrate decompression is concentrated up to medicinal extract.The method of the present invention can turn waste into wealth, and the water chestnut skin for having no utility value originally is formed with to the paste of medical value, and entire extraction process is simple, it is reused after used etoh solvent is recyclable, decolorization adsorption processing has been carried out compared with prior art, and product is purer, and impurity is less.
Description
Technical field
The invention belongs to plant deep process technology fields, and in particular to a kind of extracting method of Shell of Water Chestnut active ingredient.
Background technology
Water chestnut is the fruit of annual herb water plant water chestnut, very universal in south China water system developed regions,
Yield is larger.Water chestnut is full of nutrition, contains abundant protein, unrighted acid and multivitamin and trace element, children
Water chestnut when tender can be eaten raw or cook when fruit, and aging fruit prepared food or can be processed into Tapioca starch, be a kind of good merchantable brand of medicine-food two-purpose,
Often eat can in clearing heat and detoxicating, beneficial stomach peace, moisturize the skin, pitch-black healthy hair.Southern region of China water system is flourishing, and water chestnut plantation history is swung
Long, it is larger.Consumer or enterprise only eat the kernel inside water chestnut, and external pericarp is often arbitrarily abandoned, both unrestrained
Take resource and generate rubbish influence environment again.Contain huge medical value in the purple black epidermis of water chestnut in fact, there are many
People did relevant research and confirms that water chestnut bark extract can inhibit hepatoma cell proliferation.During producing water chestnut plant amylum
Arbitrarily discarding is very unfortunate for the Shell of Water Chestnut of generation, seems more important if can fully utilize and extract useful component.
Invention content
It is an object of the invention to fully develop the utility value of water chestnut, one kind is provided and extracts active constituent from water chestnut skin
Method, this method extracted by organic solvent, can lower cost extract the higher extraction cream of economic value for pharmacy.
To achieve the above object, the method applied in the present invention is as follows.
A kind of extracting method of Shell of Water Chestnut active ingredient, includes the following steps：（1）It collects Shell of Water Chestnut and cleans and drain the water
Point, it is crushed；（2）Shell of Water Chestnut powder is mixed with ethanol solution, heating stirring extracts；（3）It adds in and lives into solution
Property charcoal adsorbed, filter；（4）Filtrate decompression is concentrated to give medicinal extract to obtain the final product.
In said program, Shell of Water Chestnut is crushed to particle no more than 0.3mm after cleaning, it is 2-4 times to crush number.
In said program, mass ratio when water chestnut powder is mixed with ethanol solution is 1:4-8, the mass fraction of ethanol solution
For 70-80%, Extracting temperature is 40-45 DEG C, and each 1h adds an ethanol solution to original volume, and it is 3-4 times to add number.
In said program, extraction is completed to add in 3% active carbon particle absorption 5-10min in backward solution, then filters,
Filter residue is cleaned repeatedly repeatedly with water, is concentrated under reduced pressure after merging filtrate at 50-60 DEG C until in paste to obtain the final product.
Compared with prior art, the present invention it has the advantages that：（1）It can make full use of first and produce water caltrop starch institute
The a large amount of water chestnut skins generated, turn waste into wealth, are made into the paste of utility value；（2）Extraction process is simple, used
It is reused after etoh solvent is recyclable, has carried out decolorization adsorption processing compared with prior art, product is purer, and impurity is less.
Specific embodiment
For those of ordinary skill in the art is made to fully understand technical scheme of the present invention and advantageous effect, below in conjunction with specific implementation
Example is further described.It will be appreciated by those skilled in the art that following embodiment is only better embodiment of the present invention, not
Any restriction is formed to the present invention.
Water chestnut is full of nutrition, has the numerous Wuhan periphery in plantation, especially lake in our province most area.The 7-8 months
Part is the water chestnut maturation listing phase, and what kind skin was thrown away after most water chestnut taking-up kernel is everywhere, extremely influences environment, large size
Pension parachute water chestnut, which is processed into after starch, can also generate a large amount of water chestnut skin wastes.Another business center of gravity-characteristic agricultural production of our company
Product deep processing project is dedicated to solving the problems, such as this based on local.The Shell of Water Chestnut after fresh peel off is collected first and is cleaned up,
Shell of Water Chestnut and kernel disengaging time are longer, bigger for the content influence of its active constituent, and stack for a long time apt to deteriorate
Or pollution, it is made to lose extraction value.The water chestnut skin cleaned up makes its grain size in 0.5mm hereinafter, broken after crushing repeatedly
It is more thorough more help to extract.Shell of Water Chestnut powder is placed in container, and it is 70% or so to add in the 5-6 times of mass fraction measured thereto
High concentration ethanol solution, 45 DEG C are heated to after stirring evenly and is extracted.It is kept stirring in extraction process, each 1h adds second
Alcoholic solution adds in activated carbon after continuously extracting 2-3 times, continues to stir 5-10min thereto to original scale.Filtering, filter residue are used
A small amount of clear water is cleaned multiple times, and is concentrated under reduced pressure after merging filtrate at 50-60 DEG C until moisture evaporation obtains oily pasty masses.
