Abstract
The invention discloses a method for extracting hesperidin from orange peels. The method comprises the following steps of carrying out alcohol extraction, subjecting an alcohol extraction solution to macroporous resin column chromatography, carrying out eluate crystallization and recrystallization, and also a step of removing impurities through water extraction before the extraction step, wherein the step of removing impurities through water extraction before the extraction step specifically comprises the substeps of adding water to the orange peels and extracting for 1-3 hours under the condition of normal temperature, and then filtering and collecting the orange peels before the next alcohol extraction step. The method disclosed by the invention is characterized in that through the operations of firstly extracting the orange peels by using water and abandoning the water extract, excessive water soluble impurities in the orange peels can be removed and the load of the subsequent purification step is greatly reduced, and in the meantime, the hesperidin content and yield of the product obtained through extraction by using lower alcohol subsequently are higher than those of a product obtained through direct extraction by using the lower alcohol without removing impurities.
Description
Technical field
The present invention relates to the extracting method of activeconstituents in plant, be specifically related to extract the method for Hesperidin from peel of Citrus reticulata Blanco.
Background technology
Hesperidin is also hesperidine, has the osmotic pressure of maintaining, strengthens capillary vessel toughness, shortens the bleeding time and reduce the effects such as cholesterol, clinically for the assisting therapy of cardiovascular system diseases, can cultivate the multiple medicine that prevents arteriosclerosis and myocardial infarction.
Hesperidin is extensively present in rutaceae, and wherein in the plant pericarp of Citrus, content is the highest.Oranges and tangerines are the main large class fruit of south China, and south is used for outlet, eats or be processed into can raw.Cannery is when cooing oranges and tangerines can, and peel of Citrus reticulata Blanco is often dropped; And in peel of Citrus reticulata Blanco, contain a large amount of Hesperidins, and reclaim peel of Citrus reticulata Blanco and can make full use of resource for deep processing or extraction Hesperidin, increase the benefit.The method of extracting at present Hesperidin from peel of Citrus reticulata Blanco or other raw material that contains Hesperidin is solvent mainly with low-carbon alcohol greatly, adopts backflow, microwave, the mode such as ultrasonic to extract, or sinks method with alkaline extraction acid.As the publication number patent of invention that is CN102718668A, a kind of method of extracting synephrine and hesperidine from the dried immature fruit of citron orange is disclosed, it is to take the dried immature fruit of citron orange as raw material, with after acid extraction synephrine, the dregs of a decoction decoct removal of impurities with weak base, then with sodium hydroxide and calcium chloride mixed solution, extract, then extracting solution adjusts pH to 3～7 crystallization to obtain hesperidine.But it is not high that the method obtains the yield of hesperidine.Publication number is the patent of invention of CN103172685A, a kind of technique of extracting hesperidine and synephrine from the dried immature fruit of citron orange is disclosed, the ethanolic soln refluxing extraction that first dried immature fruit of citron orange is contained to alkali through petroleum ether degreasing, use, the concentrated upper KLFC-150 macroporous resin column absorption of extracting solution, use ethanol stepwise elution, elutriant condensing crystal makes hesperidine sterling again.The method can obtain higher hesperidine yield and higher purity, but it need to use organic solvent sherwood oil, and operator healthy had to certain harm.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of method of extracting Hesperidin from peel of Citrus reticulata Blanco.The method can obtain higher Hesperidin yield, and in products obtained therefrom, the content of Hesperidin is higher; The reagent toxicity adopting in whole method is low, little to human health damage.
The method of extracting Hesperidin from peel of Citrus reticulata Blanco of the present invention, comprise alcohol extracting, macroporous resin column chromatography on alcohol extract, the step of elutriant crystallization and recrystallization, unlike the prior art: the step that also comprised water extraction removal of impurities before extraction step, specifically peel of Citrus reticulata Blanco is added to water lixiviate 1～3h under normal temperature condition, filter, collect the alcohol extracting operation that peel of Citrus reticulata Blanco carries out next step.By peel of Citrus reticulata Blanco first by flooding and discard the operation of water extraction liquid, can remove water-soluble impurity too much in peel of Citrus reticulata Blanco, greatly reduced the burden of postorder purification procedures, made the follow-up product that extracts gained by low-carbon alcohol than the removal of impurity not simultaneously and directly by low-carbon alcohol, extract that the content of hesperidin of products obtained therefrom is higher, yield is higher.
The above-mentioned method of extracting Hesperidin from peel of Citrus reticulata Blanco, specifically comprises the following steps:
1) take peel of Citrus reticulata Blanco as raw material, add water lixiviate 1～3h under normal temperature condition, filter, discard filtrate, collect peel of Citrus reticulata Blanco;
2) by step 1) peel of Citrus reticulata Blanco of gained extracts by the low-carbon alcohol of 60～80v/v%, collects extracting solution;
3) extracting solution is concentrated into the medicinal extract without alcohol taste, crosses nonpolar or low-pole macroporous resin column after dilute with water, first washes resin column to effluent liquid with water and clarifies, and then uses the low-carbon alcohol wash-out of 60～80v/v%, collects the alcohol eluen containing target component;
4) alcohol eluen is concentrated, standing crystallization, collects coarse crystal;
5) coarse crystal dissolves by 50～65v/v% low-carbon alcohol, adds activated carbon decolorizing, filters, and cooling recrystallization, collects crystal, dry, obtains Hesperidin.
In aforesaid method,
Step 1), in, the add-on of water is generally 5～8 times of raw material weight.Described normal temperature refers to the scope of 10～30 ℃.
Step 2) in, the operation of extracting by low-carbon alcohol is same as the prior art, can be refluxing extraction, supersound extraction or microwave extraction, preferably adopt refluxing extraction, the number of times of refluxing extraction is generally 1～3 time, each 1～2h that extracts, while extracting, the add-on of low-carbon alcohol is generally 5～10 times of raw material weight at every turn.
Step 3), in, the model of described nonpolar or low-pole macroporous resin is HPD-100, D-101, LX-21 or AB-8 etc.In the process of wash-out, adopting thin-layer chromatography (TLC) to follow the tracks of detects.In this step, after conventionally with the water that is equivalent to 4～8 times of medicinal extract, medicinal extract being diluted after nonpolar or low-pole macroporous resin column.
Step 4), in, normally alcohol eluen is concentrated into medicinal extract (15～20 Baume) and carries out standing crystallization.
Step 5), in, the consumption of gac (g) is generally 0.3～0.5% of the solvent volume (mL) used in recrystallization process.
In aforesaid method, described low-carbon alcohol is methyl alcohol or ethanol.
Compared with prior art, feature of the present invention is:
1, by peel of Citrus reticulata Blanco first by flooding and discard the operation of water extraction liquid, can remove water-soluble impurity too much in peel of Citrus reticulata Blanco, greatly reduce the burden of postorder purification procedures, made the follow-up product that extracts gained by low-carbon alcohol than the removal of impurity not and directly by low-carbon alcohol, to extract the content of hesperidin of products obtained therefrom higher simultaneously.
2, after alcohol extract concentration and recovery alcohol, dilute with water enters purification with macroreticular resin, can remove most of impurity, is convenient to follow-up crystallization operation, makes yield higher.
