摘要:
The present invention relates to a method for mass production of taxol by semi-continuous culture of Taxus genus plant with a high yield. According to the present invention, taxol can be prepared with a high yield, by employing semi-continuous culture of Taxus genus plant cell, which comprises: (i) inoculating Taxus genus plant cell on a medium containing 1 to 10% (w/v) sugar, and incubating it; and, (ii) transferring 1/10 to 1/2 volume of the culture obtained in the step (i) to a fresh medium and repeating the step (i), adding 1 to 10% (w/v) sugar to the remnant culture and incubating to the time of maximum production of taxol.

This invention is directed to a method for efficiently separating and purifying 13-dehydroxybaccatin III and 10-deacetylpaclitaxel with a high purity of 90% or higher purity, preferably 99.5% or higher purity, from taxane-containing materials such as Taxus species, and the thusly obtained highly pure 13-dehydroxybaccatin III and 10-deacetylpaclitaxel can be used as semi-synthetic precursors of paclitaxel and/or docetaxel that are anticancer agents.
摘要:
The present invention provides a method for mass production of taxol which comprises adding sugar into a culture medium containing sugar in the course of semicontinuous culture of Taxus genus plant cell, and a universal method for mass production of taxol which comprises culturing Taxus genus plant cell in a culture medium containing sugar and AgNO3 as well. In accordance with the present invention, large amount of taxol can be produced with a high yield, simply by manipulating the culture condition of Taxus genus plant cell culture.

The present invention relates to a rapid and simple method for mass production of taxol from the cell culture of Taxus genus plant with a high purity and recovery. The method for mass production of taxol from Taxus genus plant of the present invention, comprises the steps of: (i) organic solvent extraction of biomass from Taxus genus plant to obtain a crude extract; (ii) synthetic adsorbent treatment of the crude extract and filtration to give filtrate; (iii) addition of hexane to the filtrate to precipitate crude taxol; (iv) fractional precipitation of the crude taxol in a mixture of alcohol and water and vacuum drying the precipitate to obtain taxol powder; and, (v) high performance liquid chromatography of the taxol powder. According to the method of the present invention, taxol of over 99% purity can be simply obtained from Taxus genus plant with a high recovery of over 90%.

This invention is directed to a method for the preparation of docetaxel having an amorphous, anhydrous crystalline, or hydrated crystalline structure. In accordance with the invention, highly pure amorphous, anhydrous crystalline, or hydrated crystalline docetaxel can be produced with a high yield by using a solvent precipitation method, colloid formation method, etc.
