Abstract

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.
