Abstract
The invention discloses an isoaloeresin D and a separation and extraction method for aloin, which takes aloe as a raw material to obtain a preliminary extraction; in high-speed counter-current chromatography, n-hexane, acetic ether, acetone and water form mobile phase at the upper part and fixed phase at the lower part so as to carry out separation and extraction, wherein the volume ratio of n-hexane to acetic ether to acetone to water is 0.5 to 0.1:4 to 6:0.5 to 2:4 to 6. The method simultaneously obtains high-purity isoaloeresin D and aloin, two monomer products, during one separation process for the first time. Used solvents have little pollution and high safety and the method has high extraction rate and simple operation and is suitable for industrial production and application. The method has wide application prospect in the extraction of active components of aloin and the bio-medical field.
Description
Technical field
The invention belongs to medicine and biological field, relate to a kind of method of extracting aloe effective constituent, be specifically related to the separating and extracting method that a kind of employing high speed adverse current chromatogram extracts Barbaloin A (Aloin) and different aloeresin D (Isoaloeresin D).
Background technology
Aloe (Aloe) is the perennial meat herbage of Liliaceae Aloe, is widely used in medicine, daily use chemicals and health care of food field.But, because the various complicacy of aloe effective constituent, and much the character of chemical ingredientss is very close, therefore separates various compositions in the aloe, obtain hectogram and even the monomeric technology of feather weight is the difficult problem that aloe basis and high-quality product development are produced always.Anthraquinone analog compound is an aloetic main pharmacodynamics composition, and Barbaloin A wherein (Aloin) and different aloeresin D (Isoaloeresin D) more become this hot research fields in recent years.Barbaloin A has another name called Barbaloin, aloin, Barbaloin in discharging body dirt, prevent arteriosclerosis, suppressing the tumor growth aspect has important effect; Different aloeresin D belongs to heteroside, because it has antibacterial and anti-inflammation functions, is fragrant local flavor prerequisite material simultaneously, has received suitable attention in field of medicaments, field of fine chemical.
At present for the extraction of aloe effective constituent, adopt silica gel, polyamide column chromatography method or macroporous adsorbent resins to carry out separation and Extraction both at home and abroad, but above-mentioned separation method complex operation more, cost is high, renders a service lowly, is difficult to carry out industrial production.High speed adverse current chromatogram (High Speed Counter Current Chromatography; HSCCC) be a kind of liquid liquid distribution chromatography stripping technique without solid-state carrier; Compare with other chromatographic technique; HSCCC is simple to operate, renders a service highly, can eliminate sample irreversible adsorption that carrier causes fully and to influences such as being infected with of sample, inactivation, sex change.Once set up good separation condition, it can realize efficient, the high purity separation of each component in the complex mixture and the preparation of a large amount of samples at short notice, so the research of separation condition and foundation are that HSCCC realizes successfully isolating key.
Because separating through it, the advantage of HSCCC on separation and Extraction, existing more at present research obtain aloetic effective constituent.Wang Chunyan etc. are moving phase down to be stationary phase mutually on solvent systems chloroform-methanol-water (9: 10.5: 8) mutually, and disposable separation obtains Barbaloin A and rhabarberone from the aloe crude drug; Processes such as Chen Cunshe were analyzed and to be drawn, with chloroform-methanol-acetone-water (9: 8: 1: 8) be the best results of solvent systems separating and purifying aloe effective constituent anthraquinones rhabarberone and Barbaloin; Pan Xia etc. are raw material with the aloe full leaf; Obtain the aloe chromone crude extract through a series of preprocessing means; Adopting chloroform-methanol-water (4: 3: 2) mixing solutions and methylene chloride-methanol-water (5: 4: 2) mixing solutions is the separated from solvent system, dissolves purity at the aloe chromone monomer more than 95% through two step HSCCC separation of pure.But above research all exists certain deficiency: (1) disposable separating obtained sample is single, though can obtain Barbaloin A (Barbaloin) and rhabarberone simultaneously, in fact Barbaloin A is the precursor substance of rhabarberone, and effect is similar; (2) solvent toxicity that is adopted is bigger, like chloroform, methylene dichloride etc., the insecurity that pollutes and produce.
And, do not see as yet that at present any report can make it obtain simultaneously with once separating the preparation process with Barbaloin A for different aloeresin D.
Summary of the invention
The objective of the invention is the deficiency to prior art, provide a kind of with high speed adverse current chromatogram once simultaneously high efficiency separation prepare the method for different aloeresin D of high purity (Isoaloeresin D) and Barbaloin A (Aloin).
The present invention realizes above-mentioned purpose through following technical scheme:
The separating and extracting method of a kind of different aloeresin D and Barbaloin A comprises the steps:
With the aloe is that starting material obtain primary extract, in high speed adverse current chromatogram, carries out separation and Extraction.
Described primary extract is to be raw material with the aloe, adds the polar solvent supersound extraction, and the gained extracting solution reclaims the solvent drying under reduced pressure and gets.Aloe raw material can be fresh aloe or aloe products, and wherein preferred raw material is the aloe medicinal material.
Described polar solvent is acetone, methyl alcohol or acetone: methyl alcohol (8～6: 2～4).Preferred solvent is an acetone.The weight ratio of solvent and raw material is 15～25: 1.
The moving phase of described high speed adverse current chromatogram solvent systems be fixed as normal hexane-ETHYLE ACETATE-acetone-water and constitute.Volume ratio wherein is a normal hexane: ETHYLE ACETATE: acetone: water=0.5～0.1: 4～6: 0.5～2: 4～6.Preferred volume ratio is a normal hexane: ETHYLE ACETATE: acetone: water=02: 5: 0.5～2: 5 can be 0.2: 5: 0.5: 5,0.2: 5: 1: 5,0.2: 5: 1.5: 5 or 0.2: 5: 2: 5.
The solvent systems of described high speed adverse current chromatogram adopts to be gone up as moving phase, following to stationary phase.
The consumption of said stationary phase, moving phase and the weight ratio of raw material are 94～120: 230～250: 0.3～0.6.
In the sepn process of described high speed adverse current chromatogram, flow rate of mobile phase is 0.8 ~ 1.2ml/min.
The column diameter that adopts when high speed adverse current chromatogram is 2.16mm, column volume 120mm, flow rate of mobile phase 1.0ml/min; Engine speed 860rpm; During sample size 500mg condition, the collection time period of different aloeresin D is 100 ~ 140min, and the collection time period of Barbaloin A is 170 ~ 250min.
The present invention is through big quantity research and cut-and-try work; Confirmed just to carry treatment technology; Selected normal hexane-ETHYLE ACETATE-acetone-water as solvent systems (what adopt usually is normal hexane-ETHYLE ACETATE-methanol-water system); Optimized its configuration proportion, will go up as moving phase, make different aloeresin D and Barbaloin A obtain ideal separation and Extraction effect.
Compared with prior art, the present invention has following beneficial effect:
