Description
Technical field
The present invention relates to field of medicine and chemical technology, in particular to a kind of purification process of taxol.
Background technique
Taxol is a kind of with the active natural organic-compound of broad spectrum anticancer.As new anticancer drug, how by
Step improves its production technology, and high-quality, low-cost taxol is prepared, is that those skilled in the art urgently solve for a long time
Certainly the problem of.
Chromatography is a kind of method highest to complex mixture separative efficiency that the mankind grasp up to now.With liquid phase
When chromatogram purification taxol, operation mostly carries out at room temperature, and filler used is inert media, the Nature comparison of mobile phase mostly
Mildly, be conducive to the natural activity for retaining taxol.
Currently, mainly using high performance liquid chromatography and crystallisation in large-scale production and preparation high-purity taxol technique
Two kinds of purification process are purified.Both purification process are complementary to one another, make the purification efficiency of taxol is higher, purification time compared with
It is short, and yield meets enterprise requirements.Wherein, high performance liquid chromatography is as purifying upstream process, to preparing high-purity taxol
There is irreplaceable role.However, the high performance liquid chromatography equipment investment being commonly used is expensive, instrument maintenance takes
With valuableness, purifying amount is smaller, seriously constrains the production capacity of high-purity taxol.
Summary of the invention
In view of the deficiencies of the prior art, it is an object of the present invention to provide a kind of purification process of taxol, can conveniently, fastly
Prompt prepares high-purity taxol, and the filler used is at low cost, and production is of large quantities, is suitable for large-scale industrial production.
The technical scheme is that a kind of purification process of taxol, includes the following steps,
1) microsphere silica gel is taken, is 1:2-4 by mass volume ratio, methylene chloride is added, homogenate is made, pours into quiet in chromatographic column
It sets；
2) taxol crude product is taken, is 1:3-5 by mass volume ratio, methylene chloride is added, dissolution obtains crude product solution；
3) methylene chloride, n-butanol and/or isopropanol are taken, is by volume 90-95:10-5 mixing, obtains eluent；
4) crude product solution of step 2) is added in chromatographic column, carries out isocratic elution using the eluent of step 3), collects
Taxol section component；
5) the taxol section component of step 4) is concentrated to dryness, is recrystallized, filtered, be dried to obtain taxol finished product.
Further, the partial size of the step 1) microsphere silica gel is 30-50 μm, and preferably 30 μm, the additional amount of homogenate is
Chromatographic column allows maximum loading amount, and the time of the standing is 12h.
Further, content >=60% of step 2) the taxol crude product.
Further, after step 4) isocratic elution, chromatographic column is cleaned, clear scouring water be methylene chloride, n-butanol and/
Or isopropanol, it is by volume 60-80:40-20 mixing, cleaning fluid volume is three times column volume, after cleaning, using one times
Column volume step 3) the eluent balance.
Further, the step 4) isocratic elution, under chromatographic solution contact plate 50-60, solvent is ethyl acetate: hexamethylene
=1:1-2 is developed the color using methanol sulphuric acid mixed liquor.
Further, the step 5) recrystallization is recrystallized using acetone, petroleum ether or n-hexane.
Specifically, the method for the step 5) recrystallization is, after taxol section component is concentrated to dryness, acetone is added, in 45-
55 DEG C dissolve, and petroleum ether or n-hexane are added under stirring condition, are cooled to room temperature, and growing the grain filters, dry, obtain recrystallization slightly
Product are repeated 3 times, then acetone is added into recrystallization crude product, dissolve in 45-55 DEG C, a volume times acetone is added under stirring condition
N-hexane, crystallization at room temperature filters, dry, obtains taxol finished product.
It has the advantages that by adopting the above technical scheme
1, purification process of the present invention utilizes single chromatographic system, using Conventional solvents according to unique solvent burden ratio, carries out
Gradient elution, can directly, quickly isolate high-purity taxol, until 99.5% or more, while there is higher product to receive
Rate, until 85% or more.If n-butanol and/or isopropanol ratios are higher than 10% in eluent, then it will appear larger polar impurity
With taxol together appearance, cause the separation of Japanese yew alkoxide component difficult, it is difficult to improve taxol purity；If n-butanol in eluent
And/or isopropanol ratios are lower than 5%, then effluent volume dramatically increases, while higher cost, is unfavorable for controlling taxol concentrate
Cost.
2, purification process of the present invention is easy to operate, and the waste material of generation is few, meanwhile, occupied area is small, and equipment investment is few, raw
Produce it is of large quantities, be suitable for large-scale industrial production.
3, the solvent that purification process of the present invention uses meets enterprise safety operation demand without risk is fired, in addition, use
Solvent is smaller to staff's injury, also helps staff's health.
4, purification process of the present invention uses volume ratio to wash for the methylene chloride of 90-95:10-5, n-butanol and/or isopropanol
De- liquid elutes small polar taxol, and big polar impurity is retained in chromatographic column, efficiently separates taxol and miscellaneous to reach
The purpose of matter.Methylene chloride, the n-butanol that the big polar impurity remained in chromatographic column is 60-80:40-20 using volume ratio
And/or isopropanol cleaning solution elutes, and to repeat loading, guarantees the purification effect of chromatographic column recycling, meets large quantities of
Measure the demand of purification of paclitaxel.
It is further described combined with specific embodiments below.
