A kind of method of purification of Radix Notoginseng total arasaponins
Technical field
The present invention relates to a kind of method with ultrafiltration and nanofiltration purification Radix Notoginseng total arasaponins.
Background technology
Membrance separation is to occur in 20 beginnings of the century, a separation technology that emerges rapidly after the sixties in 20th century.Membrane separation technique is owing to have separations, concentrated, purification and purified function concurrently; Efficient, energy-saving and environmental protection are arranged again, molecular level filters and filter process is simple, be easy to characteristic such as control; Therefore; Be widely used in food, medicine, biology, environmental protection, chemical industry, metallurgy, the energy, oil, water treatment, electronics, field such as bionical at present, produced huge economic benefit and social benefit, become one of most important means in the current separation science.
Ultrafiltration is a kind of membrane separation technique; Its main part is a ultrafilter membrane, is used for other separation of solution material macromole level, and ultra-filtration process is to be power with film pressure at both sides difference; A kind of solution separating process that is the basis with the mechanical grading principle; Working pressure is generally 0.1Mpa-0, and 25Mpa separates about the 1 μ m-0.1 μ m molecular cut off 500-1000000Dalton of aperture.Ultrafiltration is different with all conventional filtrations and microporous filter (being static filtering), and the one, the ultra-filtration and separation footpath is little, almost can hold back all antibacterials, virus and colloidal particles in the solution, protein, larger molecular organics.The 2nd, whole filter process carries out under dynamically, and solvent only obtains the separation of part.Get into the material liquid of ultrafiltration module, under the promotion of film pressure at both sides difference, part sees through film becomes ultrafiltrate, and all the other then become concentrated solution and pour, and make the film surface can not see through material and be merely limited gathering.Filtering rate can reach an equilibrium valve and unlikely continuous decay under steady statue, whole process can continue for a long time.
Nanofiltration also is a kind of membrane separation technique, and is optional from 200~1000Dalton to the rejection to organics molecular weight, and salt is had moderate above removal efficiency.Has inspissation simultaneously.
Ultrafiltration, nanofiltration membrane separation technology are suitable for realizing the specific (special) requirements of some process procedures in the existing Chinese medicine extraction process, help improving the inherence and the external quality of Chinese medicine compound preparation.
Along with rapid development of national economy, the application of membrane separation technique not only can be more and more widely, and it can and be accepted by increasing people's understanding.According to the preliminary statistics; Calendar year 2001 whole world film and the sales volume of membrane module near 8,000,000,000 US dollars; The market of complete set of equipments and film engineering has then reached tens billion of US dollars, and also increases progressively in the amplitude with 10%~20% every year, demonstrates the bright prospects of this new industry.
The quality problems of Chinese medicine cause concern day by day in recent years; And XUESAITONG, XUESHUANTONG ZHUSHEYE that preparation consists of the Radix Notoginseng total arasaponins sodium chloride injection also exist medicine stability, safety issue as one of maximum Chinese medicine kind of sales volume in the market.Its main cause is because the complex chemical composition of Chinese medicine own has materials such as protein, vitamin, organic acid, saccharide, aminoacid, oils and fats, wax, enzyme, pigment, tannin, inorganic salt, volatile oil, alkaloid, glycoside usually.Wherein existing effective ingredient has invalid impurity again, just owing to impurity such as inorganic salt, tannin, protein and macromolecular substances are not effectively removed, has just influenced stability of formulation and safety.Be raw material at present with the Radix Notoginseng, extract the production technology of Radix Notoginseng total arasaponins, can't small-molecule substance impurity such as inorganic salt and part macromolecular substances impurity be eliminated, make XUESAITONG, XUESHUANTONG ZHUSHEYE have stability, safety issue.
Summary of the invention
The objective of the invention is to extract the application in the Radix Notoginseng total arasaponins production technology through membrane ultrafiltration and nanofiltration Radix Notoginseng, the Radix Notoginseng total arasaponins of further purifying is held back low molecular impurities such as macromolecule and inorganic salt, satisfies the needs of pin with raw material.Also can be used for the Radix Notoginseng total arasaponins is raw material, the preparation production technique of preparation XUESAITONG ZHUSHEYE.
The present invention increases membrane ultrafiltration, nanofiltration in existing Radix Notoginseng total arasaponins production technology.Membrane ultrafiltration, nanofiltration technique are increased in after the titanium rod fillter section, and then concentrate.That is: an amount of needle-use activated carbon of Radix Notoginseng → pulverizing → ethanol lixiviate → go up macroporous resin column → peroxidating aluminum post → add, titanium rod filtrations → ultrafiltration → nanofiltration → refining is concentrated → drying → pulverizing → Radix Notoginseng total arasaponins.
Ultra-filtration process is held back macromolecule impurity; Nanofiltration process is held back small-molecular weight inorganic salt impurity, can concentrate filtrating simultaneously, realizes that purification concentrates purpose.
The molecular cut off of above-mentioned ultrafilter membrane generally is adopted as 10000~100000Da, preferred 100000Da.The molecular cut off of NF membrane adopts 200~500Da.
Membrane structure of the present invention can adopt hollow fiber ultrafiltration membrane, rolling or tubular ultra-filtration membrane, preferred rolling ultrafilter membrane.Both can adopt cross flow filter, also can adopt dead-end filtration, preferred cross flow filter.
The operating condition of ultrafiltration, nanofiltration technique is following:
1) inlet hydraulic is 0.1~0.5Mpa;
2) the feed liquid flow velocity is 0~55ml/s, preferred 10~40ml/s;
3) feed temperature is 15~50 ℃, is preferably 20~40 ℃;
4) when feed liquid stock solution is extremely a small amount of by ultrafiltration, add the purified water dilution again, repeat ultrafiltration repeatedly;
5) pH value of feed liquid is controlled at 5~9, and preferred 6.0~7.5;
6) backwash: backwashing period is every batch, and backwashing time is 1.5h;
The present invention also is applicable to the Radix Notoginseng total arasaponins to be raw material simultaneously, produces the production process of injection.
The present invention with ultrafiltration and nanofiltration to Radix Notoginseng total arasaponins separate, concentrate, refining, advantage such as have that production procedure is simple, easy and simple to handle, good separating effect, bioactive substance are not destroyed is very ideal impurity-removing method.Small-molecule substance impurity such as macromolecular substances impurity and inorganic salt can be effectively removed, the purity of Radix Notoginseng total arasaponins can be improved.
