Description
Technical field
The present invention relates to the separating and purifying technology of vinorelbine, more particularly to a kind of preparing chromatograph in industry purifying length
Spring Rui Bin method, belongs to chemical pharmacy field.
Background technology
Vinorelbine（English name：vinorelbine）It is the plant series antineoplastic medicament of the listing nineties in last century, so far
It is still the First-line chemotherapy medicine of the common cancers such as breast cancer, non-small cell lung cancer that the comprehensive cancer guide of American National is recommended
Thing, and it is widely used in other malignant tumours such as oophoroma, lymthoma.It by with tubulin binding, cell is being had silk
Micro-pipe formation obstacle in fission process, structural formula is as follows：
Vinorelbine
It is few that the country is studied vinorelbine technical grade isolation and purification method.Chinese patent CN10781322A is disclosed
A kind of isolation and purification method of vinorelbine crude product, after crude product is eluted through alkali alumina post, obtains just sterling, then through C18It is anti-phase
Filled column is eluted, and eluent is extracted through dichloromethane, again with methanol is recrystallized to give vinorelbine sterling；
Chinese patent CN 102199165A disclose vinorelbine crude product through silica gel column chromatography, alkali alumina column chromatography
The technique for obtaining high purity product afterwards, but the processing step is various, and production cost is high, is not suitable for industrialized production.
Chinese patent CN103788117A discloses lab scale purifying process of the vinorelbine as intermediate products, by silica gel
Column chromatography, product purity is up to more than 99%, but yield is only 27% or so, and the process economy is low, is not suitable for industrialized production.
The present invention have studied a kind of method that preparing chromatograph in industry prepares high-purity vinorelbine, and product purity is high（98% with
On）, and process recovery ratio is stable, is adapted to industrialized production.
The content of the invention
For problems such as the low, complex process of vinorelbine purification efficiency, it is an object of the invention to provide a kind of high-purity, behaviour
The property made is strong, be adapted to the purification process of the vinorelbine of industrialized production.
To achieve these goals, the present invention is adopted the following technical scheme that：
A kind of purification process of vinorelbine, comprises the following steps：
（1）Use organic solvent A be swelled after silica gel for chromatographic column filler prepare chromatographic column；
（2）Above-mentioned chromatographic column will be added with organic solvent A after vinorelbine dissolving crude product；
（3）Chromatographic column is eluted using the method for gradient elution, the organic solvent being gradually reduced successively with volume ratio
A/ organic solvent B mixed liquors are eluted as eluent, collect main composition efflux, lower residue is finally washed with solvent；
（4）Be concentrated under reduced pressure recovery eluant, eluent, obtains high-purity vinorelbine, more than the wt% of purity 98, and yield is 60~
98%。
In above-mentioned preparation method：
Step（1）In, silica gel is used for 100~400 mesh；
Step（1）In, the organic solvent A is dichloromethane, n-butanol, methyl isopropyl ketone, ethyl acetate, chloroform, two
One kind in the ring of oxygen six；
Step（2）In, vinorelbine applied sample amount is 1~6 (w/w%), and inlet amount is the 1~12% of preparation chromatogram column volume；
Step（3）In, the organic solvent B is one in acetone, acetonitrile, dimethylformamide, methanol, dimethyl sulfoxide
Kind；
Step（3）In, eluant, eluent is entered using constant pressure and flow pump, eluant, eluent is followed successively by solvent orange 2 A：B=99：1~75：1(v/v)、
Solvent orange 2 A：B=65：1~45：1 (v/v), solvent orange 2 A：B=45：1~15：1 (v/v), eluting agent for column volume 200~
500%, elution flow rate is the 1~10% of elution column volume per minute；The pressure for preparing chromatographic column operation is 0.1~0.7 MPa；
Step（3）In, eluent Fractional Collections, collection is divided to two sections, and first paragraph collects solvent orange 2 A：B=65：1~45：1(v/v)
Cut, is the relatively low vinorelbine eluent of content；Second segment collects solvent orange 2 A：B=45：1~15：1 (v/v) cut, predominantly
High concentration vinorelbine eluent.
Step（3）In, using solvent orange 2 A：B=15：1~5：1 (v/v) elutes residue.
The present invention, by silica gel preparing chromatograph in industry purifies and separates, is realized high-purity using vinorelbine crude product as initiation material
Spend the preparation of vinorelbine.The invention has the advantages that：
1st, product purity is high, and this method can make the purity of vinorelbine reach more than 98%, and yield is 60~98%.Stationary phase
It is stable, it is reusable；
2nd, the eluant, eluent that uses of the present invention is easily reclaimed, can Reusability, production cost is low；
3rd, technical process is simple, and equipment disposably puts into small, and energy consumption is low, workable, is adapted to industrialized production.
