Abstract
The invention discloses a kind of method extracting flavone from poplar bud, belong to compound separation and extract field.The method with water or alcohol for Extraction solvent, by by methods such as poplar bud soaking cooking, squeezing, separation and pulverizing, obtained poplar bud flavone extract, extraction ratio is higher, and water extraction method reaches more than 90%, and alcohol extracting method reaches more than 95%, be conducive to making full use of of poplar bud, save resource.<!--1-->
Description
Technical field
The present invention relates to a kind of extracting flavonoids method, particularly relate to a kind of method extracting flavone from poplar bud, belong to compound separation and extract field.
Background technology
Willow is that Apis gathers propolis topmost glue source plant, and poplar bud contains a large amount of flavone compounds, thus has medical value, can diuretic relieving constipation, relieving heat toxin, anthelmintic.Have bibliographical information poplar bud alcohol extract composition and propolis very close, there is good development and application values.The method extracting flavone at present from poplar bud has: distilled water, acetone, ethyl acetate, alcoholic solution 4 kinds of methods, it has been generally acknowledged that 70% alcoholic solution
extractmethod is reasonable method.
But the deficiency that ubiquity extraction ratio is low.
Summary of the invention
The object of the invention is to provide a kind of method extracting flavone from poplar bud, reaches higher extraction ratio.
For realizing the object of the invention, technical scheme is as follows:
The bud time is got in selection: after the fallen leaves of willow then (late October) to next year Folium Populi Pseudo-simonii grow before (late March), this period of time is the preferably opportunity of winning poplar bud.
Select poplar bud: best with the blue willow of sand, two or seven willows, gel content is about 33%.
Extract and realize as follows:
(1) water extraction method
1, by poplar bud soaking cooking: first poplar bud is put in pot, add water logging and firmly set bud, soak 12 hours (room temperature), then boil, insulation 15-30 minute;
2, squeeze: pulled out by the poplar bud boiled with strainer, be placed in wax press (or replacing with oil press) extruding, namely glue is squeezed out, and accepts with container;
3, heavy marc dregs: the residue dregs after squeezing, be soaked in water 6-12 hour, Repeat-heating, then squeeze once;
4, heavy bubble tree bud: the gummy liquid that second time squeezing is collected is soaked with mixing under new poplar bud room temperature, then heat and squeeze;
5, finished product: above-mentioned gum-solution is down to room temperature, releases yellow supernatant after leaving standstill.By the khaki pasty masses obtained, i.e. poplar bud flavone.
The supernatant of releasing can be used further to soak poplar bud, recycles.
(2) alcohol extracting method
1, tear: utilize machinery that tree bud is torn, shredded, also can not deal with;
2, lixiviate: poplar bud is placed in Plastic Drum, adds the edible ethanol of mass percent 75%, soaks 12 hours under room temperature;
3, squeeze: pulled out by soaked poplar bud, be placed in wax press tool (or replacing with oil press), tree bud glue of squeezing out, accepts;
4, heat: by heating in water bath or Steam Heating, be heated to 60 degree, and constantly stir, make resin be dissolved in ethanol completely;
5, circulation is squeezed
(1) increase: alcohol recycle utilizes, under room temperature, new poplar bud raw material is placed and wherein soaks 6-12h;
(2) dregs after squeezing glue for the first time recycle alcohol-pickled 6h, repeat to squeeze once;
6, be separated: the natural gum of squeezing out through supercooling, sink clear go out, pour out supernatant continue soak tree bud;
8, evaporate: by clear go out gummy liquid be heated to 60 degree under vacuum conditions, cooling, pulverize.By the alcohol recycle of volatilization.
The method extracting flavone from poplar bud provided by the invention, extraction ratio is higher, and water extraction method reaches more than 90%, and alcohol extracting method reaches more than 95%, is conducive to making full use of of poplar bud, has saved resource.
Detailed description of the invention
For better illustrating the present invention, as follows for embodiment:
Select husky blue willow poplar bud: after annual late October willow fallen leaves, win poplar bud to late March Folium Populi Pseudo-simonii in next year before growing, its gel content is about 33%.
Extract and realize as follows:
(1) water extraction method
1, by poplar bud soaking cooking: first poplar bud is put in pot, add water logging and firmly set bud, soak 12 hours (room temperature), then boil, insulation 15-30 minute;
2, squeeze: pulled out by the poplar bud boiled with strainer, be placed in wax press (or replacing with oil press) extruding, namely glue is squeezed out, and accepts with container;
3, heavy marc dregs: the residue dregs after squeezing, be soaked in water 6-12 hour, Repeat-heating, then squeeze once;
4, heavy bubble tree bud: the gummy liquid that second time squeezing is collected is soaked with mixing under new poplar bud room temperature, then heat and squeeze;
5, finished product: above-mentioned gum-solution is down to room temperature, releases yellow supernatant after leaving standstill, and namely obtains khaki paste natural gum flavone extract.
The supernatant of releasing can be used further to soak poplar bud, recycles.Flavone extract reaches 91% after measured.
(2) alcohol extracting method
1, tear: utilize machinery that tree bud is torn, shredded;
2, lixiviate: poplar bud is placed in Plastic Drum, adds the edible ethanol of mass percent 75%, soaks 12 hours under room temperature;
3, squeeze: pulled out by soaked poplar bud, be placed in wax press tool (or replacing with oil press), tree bud glue of squeezing out, accepts;
4, heat: by heating in water bath or Steam Heating, be heated to 60 degree, and constantly stir, make resin be dissolved in ethanol completely;
5, circulation is squeezed
(1) increase: alcohol recycle utilizes, under room temperature, new poplar bud raw material is placed and wherein soaks 6-12h;
(2) dregs after squeezing glue for the first time recycle alcohol-pickled 6h, repeat to squeeze once;
6, be separated: the natural gum of squeezing out through supercooling, sink clear go out, pour out supernatant continue soak tree bud;
8, evaporate: by clear go out gummy liquid be heated to 60 degree under vacuum conditions, evaporate ethanol, then cool, pulverize.By the alcohol recycle of volatilization.Flavone extract reaches 96% after measured.
