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.
摘要:
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%.
