Description

In a kind of sophora bud, extract the method for rutin
Technical field
The application relates to a kind of method of extracting rutin from the sophora bud.
Background technology
The sophora bud is the dry flower and alabastrum of leguminous plants Chinese scholartree, the history of being used as medicine existing more than 2000 year, and < < Shennong Bencaojing > > is classified as top grade.The rutin containing in the sophora bud approximately 8%~28%(according to the sophora bud place of production and collect the difference of time and difference to some extent).Rutin claims again violaguercitrin, rutin, belongs to flavonoid glycoside compound, has cooling blood for hemostasis, the effect of clearing liver-fire, can reduce capillary permeability and fragility, promote hyperplasia and prevent that hemocyte from condensing, also have anti-inflammatory, antianaphylaxis, diuresis, antibechic, reducing blood-fat etc. effect.Rutin clinically as the assisting therapy of essential hypertension, prevent because rutin lacks other hemorrhages that cause and prevention and treatment diabetes and merge hyperlipidemia.In addition, rutin is as natural antioxidant and use yellow pigment, is also widely used in protective foods and cosmetic kind.
In prior art, common rutin extraction method has that boiling water decocts, alkali carries heavy, the ultrasonic or microwave extraction of acid, Soxhlet extraction, supercritical CO 2extract etc.Common purification process has crystallization, macroporous adsorbent resin processing, high performance liquid chromatography processing etc.; Along with tensio-active agent being widely used in fields such as chemical industry, food, daily necessities production and water treatments, water insoluble or not soluble in water effective constituent in a lot of Chinese medicine, as Flavonoid substances, alkaloid, volatilization wet goods, can on its surface or interface, form adsorption by tensio-active agent, or in solution, form molecule aggregation body, and then change the solvability of these compositions in the aqueous solution, improved the extraction efficiency of Chinese medicine, reduced extraction cost, the feature of safety and environmental protection.In prior art, there is the report that adopts the auxiliary Extraction of rutin of tensio-active agent, but adopt a kind of tensio-active agent more.As (" the improvement researchs of Rutin Extracting Technology " such as Li Jinxiu, Li Jinxiu, Gong Shengzhao, Huang Qiujin, Guangdong chemical industry, the 1st phase in 2003, P15) adopted following methods to carry out the extraction of violaguercitrin: the sophora bud is pulverized, the water that adds 5 times of amounts, with liming, regulate pH8~9, in temperature, be 50~60 ℃ and extract 20~30min, filter, by similarity condition, repeatedly extract 3 times, filtrate is 3 with salt acid for adjusting pH, add 0.5% Surfactant OP, at 60~70 ℃ of insulation 10min, standing 30min, filter, washing, dry, obtain violaguercitrin product yield 18.4%, content 96%.
Summary of the invention
The application aims to provide a kind of new method of extracting rutin from the sophora bud.
The method of the invention comprises the following steps:
(1) pre-treatment: will be dried the sophora bud and process 30min with dry blowing method at 70 ℃, then go out colloid with 70 ℃ of hot water drip washing, and dried afterwards and pulverize the order into 20-80;
(2) extract: sophora bud particle is added to 1~5% borax, 1~5% Na 2sO 3in 15-30 60~70% ethanol doubly, use sodium bicarbonate to regulate pH to 9~10, add again 0.3~0.5% Tween 20 and 0.05~0.3% OP-15, lucifuge ultrasonic extraction 10~30min under 20~30kHz, the condition of 30~50 ℃, filter afterwards, filtrate lucifuge at 30~50 ℃ is standby; Filter residue extracts once with above-mentioned same condition again, and the filtrate obtaining merges with filtrate before, in the filtrate after merging, adds 5% gac, at 30~50 ℃, lucifuge stirs 10min, the filtrate of filtering after carbon removal is acidified to pH=3~4, standing 20~30min, suction filtration obtains rutin crude product;
(3) refining: rutin crude product is placed in to baking oven, at 40 ℃, dry extremely without alcohol taste, be warming up to gradually again 130 ℃ of oven dry, the dry rutin obtaining is added in propyl carbinol and is heated to dissolve, filter, in filtrate, add deionized water, adopt 20~30kHz ultrasonic at 0~5 ℃ lucifuge process 20~30min, standing crystallization is also dried at 130 ℃, obtains more than 98% rutin of purity, and yield reaches more than 22%.
Further, in step of the present invention (2), preferably add 3~4% borax and 1% Na 2sO 3.
Further, in step of the present invention (2), preferably add 0.35~0.45% Tween 20 and 0.05~0.2% OP-15.
Further, in step of the present invention (2), the condition optimization of ultrasonic extraction extracts 15~25min at 30kHz, 40~50 ℃.
Further, in step of the present invention (3), adding the volume of propyl carbinol and the ratio of sophora bud raw materials quality is 20~30mL/g; Adding the volume of deionized water and the ratio of sophora bud raw materials quality is 2~3mL/g; The condition optimization of ultrasonication is processed 20~30min under 30 kHz.
Further, in step of the present invention (2), be more preferably and add 0.35~0.45% Tween 20 and 0.05~0.15% OP-15.
The present invention has used tensio-active agent Tween 20 and the OP-15 of rational proportion in extraction step, and the tensio-active agent of this proportioning makes extraction time and crystallization time all have shortening, and extraction efficiency improves, then is aided with ultrasonic wave, and yield is increased obviously.Adopt propyl carbinol to refine rutin, can effectively remove the impurity such as residual colloid, lipid acid, improve the purity of rutin.Comprehensive each step of the present invention, the method for the invention is easy and simple to handle, and extraction efficiency is high, is applicable to produce actual.
