Abstract
A kind of method of from tea waste, directly extracting refined saponin, at first with tea oil pin waste material through the ethanol lixiviate, leaching liquid concentrates evaporate to dryness after filtering and gets intermediates, intermediates and organic mixed solvent effect, make refining saponin through extracting, the saponin drying is handled, and crushing packing promptly gets required refined saponin.This method extraction rate reached 40%, product purity reaches more than 90%, and whiteness is that cost is low, and is pollution-free, easy to operate about 40 degree.
Description
The present invention relates to a kind of method of from tea oil pin waste material, directly extracting refined saponin.
The oil tea soap is widely used in aspects such as light industry, weaving, medicine, chemical industry, and it is to extract from the grouts after the oil expression.The extracting method of introducing in 1987 the 6th phases " daily chemical industry " magazine, owing to adopt hydrogen peroxide to make dewatering agent, its decolorizing effect is not good, and product acidity is increased to about PH=4, and is bigger to the human body skin pungency, influenced range of application.China's application for a patent for invention on March 21 in 90 year disclosed (application number 89105715.3) " is extracted the process for purification of saponin " from pressed cake of camellia seeds, in treating process, need to use S-WAT or hydrogen peroxide as finishing agent, also with caustic alkali or clorox (or calcium) as neutralizing agent, can make the overweight and skin irritation of product alkalescence.
Task of the present invention is to adopt two kinds of organism mixed solvents to carry out purifying, decolouring, to improve product purity and whiteness.
The technical scheme of invention is achieved in that tea oil pin waste material is through the ethanol lixiviate, leaching liquid filtering and concentrating evaporate to dryness is got intermediates, intermediates and organic mixed solvent effect are after extracting must be made with extra care saponin, and refining saponin crushed after being dried packing promptly gets required refined saponin.
Ethanol is added lixiviate in the oil foot slurry, be advisable with 95% ethanol, temperature is controlled at about 65 ℃, and slurry and alcoholic acid weight ratio are 1: 2～3, carry out in stainless steel vessel.
When leaching liquid filters, keep 65 ℃ of left and right sides temperature, in order to avoid the saponin crystallization is separated out.With heating in water bath filtrate is concentrated evaporate to dryness.
Concentrate intermediates behind the evaporate to dryness (intermediates also can come extract thick saponin) in pressed cake of camellia seeds, mix the pasty state that the reduces to pulp extraction tower of packing into mixed organic solvents, temperature is controlled at about 60 ℃, and extracting a few hours get white refining saponin.
Refining saponin carries out drying under 70 ℃ of left and right sides temperature, divide packing then.
Effect of the present invention is: saponin extraction yield height, can reach 40%, and product purity reaches more than 90%, and whiteness is that operating process can keep PH=7～8 about 40 degree, and cost is low, and is pollution-free, easy to operate.
Introduce the present invention in detail below in conjunction with embodiment.
Get 100 gram oil foot slurries and place 1000 ml beakers, add 250 milliliter 95% dissolve with ethanol leaching, be incubated with calico, be controlled at and carry out the filtration first time about 65 ℃, with filtering low insulation about 65 ℃, carry out the second time and filter then, filtrate water is bathed and is added thermal distillation recovery ethanol.Pour out when being the sauce dark solution when being concentrated into, use the heating in water bath evaporate to dryness again, cooling is intermediates (weight is about 71.5 grams), add ether and acetone mixed solution then, the shape that reduces to pulp injects extractor extracting 5 hours, takes out then to be placed in the thermostat container with 65 ℃ of temperature dryings.Can get 40 gram content is 90.5%, and whiteness is the refined saponin of 38 degree, and extraction yield is 56%.
Claims (4)
1, a kind of method of from tea waste, directly extracting refined saponin, it is characterized in that: tea oil pin waste material is through the ethanol lixiviate, leaching liquid is filtered, concentrated evaporate to dryness gets intermediates, intermediates and organic mixed solvent effect are after extracting must be made with extra care saponin, refining saponin crushed after being dried packing promptly gets required refined saponin.
