Abstract
The invention discloses a method for extracting flavones from poplar buds, which belongs to the field of compound separation extraction. The method comprises the following steps: taking water or alcohol as an extracting solvent, and performing methods of soaking, stewing, squeezing, separating, grinding and the like on poplar buds to prepare a poplar bud flavone extract. According to the method, the extracting rate is relatively high, the water extraction rate is more than 90%, the alcohol extraction rate is more than 95%, the poplar buds can be fully utilized, and resources are saved.
Description
Technical field
The present invention relates to a kind of flavone extracting method, relate in particular to a kind of method of extracting flavone from poplar bud, belong to compound separation and extract field.
Background technology
Willow is that Apis gathers the topmost glue of propolis source plant, and poplar bud contains a large amount of flavone compounds, thereby has medical value, can diuretic relieving constipation, relieving heat toxin, and anthelmintic.There are bibliographical information poplar bud alcohol extract composition and propolis very approaching, there is good development and application values.The method of extracting at present flavone from poplar bud has: distilled water, acetone, ethyl acetate, 4 kinds of methods of alcoholic solution, it has been generally acknowledged that 70% alcoholic solution extraction method 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 of 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 in 33% left and right.
Extract as follows and realize:
(1) water extraction method
1, by poplar bud soaking cooking: first poplar bud is put in pot, adds water logging and firmly set bud, soak 12 hours (room temperature), then boil, insulation 15-30 minute;
2, squeezing: with strainer, the poplar bud boiling is pulled out, be placed in wax press (or replacing with oil press) extruding, glue is squeezed out, and accepts with container;
3, heavy marc dregs: the residue dregs after squeezing, the 6-12 hour that is soaked in water, Repeat-heating, then squeeze once;
4, heavily bubble is set bud: the gummy liquid that squeezing is collected is for the second time mixed to immersion with under new poplar bud room temperature, then heating is squeezed;
5, finished product: above-mentioned gum-solution is down to room temperature, emits yellow supernatant after standing.By the khaki pasty masses obtaining, i.e. poplar bud flavone.
The supernatant of emitting 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 to Plastic Drum, adds the edible ethanol of mass percent 75%, soak under room temperature 12 hours;
3, heating: by heating in water bath or Steam Heating, be heated to 60 degree, and constantly stir, make resin be dissolved in ethanol completely;
4, squeezing: soaked poplar bud is pulled out, be placed in wax press tool (or replacing with oil press), the tree bud glue of squeezing out, accepts;
5, circulation is squeezed
(1) increase: ethanol is recycled, under room temperature, new poplar bud raw material is placed and wherein soaked 6-12H;
(2) dregs that squeeze for the first time after glue recycle alcohol-pickled 6H, repeat to squeeze once;
6, separation: the natural gum of squeezing out is through supercooling, sinks to clearly going out, and pours out supernatant and continues to soak tree bud;
8, evaporation: the clear gummy liquid going out is heated to 60 degree under vacuum state, cooling, pulverize.The ethanol of volatilization is reclaimed.
The method of 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.
The specific embodiment
For the present invention is better illustrated, as follows for embodiment:
Select husky blue willow poplar bud: after annual late October willow fallen leaves to next year late March Folium Populi Pseudo-simonii before growing, win poplar bud, its gel content is in 33% left and right.
Extract as follows and realize:
(1) water extraction method
1, by poplar bud soaking cooking: first poplar bud is put in pot, adds water logging and firmly set bud, soak 12 hours (room temperature), then boil, insulation 15-30 minute;
2, squeezing: with strainer, the poplar bud boiling is pulled out, be placed in wax press (or replacing with oil press) extruding, glue is squeezed out, and accepts with container;
3, heavy marc dregs: the residue dregs after squeezing, the 6-12 hour that is soaked in water, Repeat-heating, then squeeze once;
4, heavily bubble is set bud: the gummy liquid that squeezing is collected is for the second time mixed to immersion with under new poplar bud room temperature, then heating is squeezed;
5, finished product: above-mentioned gum-solution is down to room temperature, emits yellow supernatant after standing, obtain khaki paste natural gum flavone extract.
The supernatant of emitting 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 to Plastic Drum, adds the edible ethanol of mass percent 75%, soak under room temperature 12 hours;
3, heating: by heating in water bath or Steam Heating, be heated to 60 degree, and constantly stir, make resin be dissolved in ethanol completely;
4, squeezing: soaked poplar bud is pulled out, be placed in wax press tool (or replacing with oil press), the tree bud glue of squeezing out, accepts;
5, circulation is squeezed
(1) increase: ethanol is recycled, under room temperature, new poplar bud raw material is placed and wherein soaked 6-12H;
(2) dregs that squeeze for the first time after glue recycle alcohol-pickled 6H, repeat to squeeze once;
6, separation: the natural gum of squeezing out is through supercooling, sinks to clearly going out, and pours out supernatant and continues to soak tree bud;
8, evaporation: the clear gummy liquid going out is heated to 60 degree under vacuum state, evaporates ethanol, then cooling, pulverize.The ethanol of volatilization is reclaimed.Flavone extract reaches 96% after measured.
