Abstract
The present invention separates and purifies taxol by means of column chromatographic process with macroporous resin, such as AB-8, D101, D201 and AK-9 as fixed phase and polar solvent, such as water solution of ethanol or acetone, as flowing phase, with the effluent flow rate is 0.6-1.5 L/hr. The effluent with taxol content lower than cephalotmannine content is concentrated and dried to obtain intermediate taxol product A; and effluent with taxol content higher than cephalotmannine content is concentrated and dried to obtain intermediate taxol product B. The said process can separate and purify coarse taxol product with 9-20% content to obtain intermediate taxol product with 40-60% content in the yield as high as 80%. The process can eliminate water soluble impurity from the coarse product.
Description
(1) technical field
The present invention relates to the separation and purification field of plant milk extract, specifically is a kind of method from the thick separation and purification of products taxol of taxol.
(2) technical background
Taxol is the most promising cancer therapy drug that recent two decades is found in the world, and cancers such as treatment mammary cancer, ovarian cancer, esophagus cancer, lung cancer, liver cancer are all had good efficacy, cancer cells is had extremely strong lethality, and toxic side effect is minimum.Therefore become the emphasis of present medicine trade research.
Taxol belongs to the diterpenes alkaloid.Beginning most is extraction separation taxol from the natural phant Ramulus et folium taxi cuspidatae.Ramulus et folium taxi cuspidatae is rare species, and natural taxus resource is very limited, and growth of taxol is slow, and natural Ramulus et folium taxi cuspidatae can't be satisfied the requirement that taxol is produced.In order to open up the new source of taxol, people have studied extraction separation taxol, yew cell cultivation production taxol and multiple biosynthesizing, semi-synthetic, complete synthesis taxol technology from the Taxus x media of artificial growth.No matter adopt which kind of technology, because the taxol synthetic ratio is low, cost is high, so taxol costs an arm and a leg.Separation and purification goes out taxol drug from the mixture of the close derivative of multiple structure, homologue in addition, and particularly be very difficult work separating of taxol and Cephalomannine.Yield has lifting slightly in the separation and purification process, promptly mean precious taxol gain and loss what, on the benefit greatest differences will be arranged.So how to improve the separation purifying technique of taxol, be the problem of generally paying attention at present.
Present separation method mainly contains silica gel column chromatography, alumina column chromatography method, and purification process mainly contains reversed phase chromatography method and silica gel column chromatography normal-phase chromatography methods such as C18 column chromatography, fluorophenyl column chromatography.
The patent application of the separation purifying technique of relevant taxol has many, as: the Chinese patent 99815315.X " from containing the method for high yield extraction of taxol material production taxol " of Phytogen Life Sciences Inc's application in 1999 prepares high-purity taxol with the acetone precipitator method, the Chinese patent " a kind of method of taxad alcohol cleaning and purifying " of Fudan University's application in 1998 uses packing normal paraffin drip washing purification of paclitaxel crude product, the Chinese patent of Meiyan Inst. of Biological Engineering, Meixian County's 2001 applications " method of taxol is extracted in enrichment from yew cell nutrient solution filtrate " carries out adsorption and enrichment with macroporous adsorbent resin and test solution thorough mixing, the organic solvent wash-out is concentrated and obtains the enriched material that height contains taxol by the taxol of resin absorption.
The weak point of existing separation purification method is that yield of taxol (promptly from feeding intake, through sequenced technical process, and calculate with the effective ingredient taxol by the output object recovery rate that obtains.The input repeatedly that does not comprise secondary output object) only be 70%; And to use inflammable, explosive or noxious solvent, and harmful as chloroform, methylene dichloride, ethyl acetate, methyl alcohol, acetonitrile etc., contaminate environment, production operation process hazard height; Applied sample amount is little in addition, and silica gel is 150 to 0.9～1.0 with the ratio of sample during general silica gel column chromatography.
(3) summary of the invention
The method that the purpose of this invention is to provide a kind of yield height and production operation safety from the thick separation and purification of products taxol of taxol.
Method from the thick separation and purification of products taxol of taxol of the present invention comprises following step:
1. content of taxol is that 9～20% the thick product of taxol is a material sample;
2. with the macroporous adsorbent resin phase that fixes, macroporous adsorbent resin is 10 ratios with the weight ratio of sample
0.9～1.4；
3. with can with water miscible, concentration is that 40～70% polar solvent aqueous solution are moving phase;
4. use the column chromatography separating and purifying taxol, sample solution is from the chromatography capital of macroporous adsorbent resin
Sample on the end;
5. during the moving phase wash-out, the effluent liquid flow velocity is 0.6～1.5 liter/hour in the chromatography column;
6. by the effluent liquid of time Fractional Collections behind chromatography, per hour collect 1 part, examine to HPLC
Survey taxol concentration stops when being lower than 0.2 mg/ml, on a time period the effluent liquid of Shou Jiing
Be divided into three parts;
7. do not have taxol substantially in the part i effluent liquid, focus on, reclaim solvent;
8. content of taxol is less than Cephalomannine content in the part ii effluent liquid, and concentrate drying gets purple
China fir alcohol intermediates A;
9. content of taxol is greater than Cephalomannine content in the III part effluent liquid, and concentrate drying gets purple
China fir alcohol intermediates B.
The present invention from the advantage of the method for the thick separation and purification of products taxol of taxol is: 1, separation and purification is effective, is that 9～20% the thick purifying products of taxol is the intermediate taxol product that contains taxol 40～60% easily with content of taxol; 2, yield height, the disposable yield of taxol is up to about 80%; 3, operational safety is not used inflammable, explosive or noxious solvent; 4, applied sample amount is big, and the weight ratio of macroporous adsorbent resin and sample is up to 10 to 0.9～1.5, when being general silica gel column chromatography 15 times of the silica gel applied sample amount; 5, can remove water-soluble impurity in the thick product of taxol.
