Methods for obtaining paclitaxel from plants containing paclitaxel are
disclosed. Plant material is first obtained from plants containing
paclitaxel. Paclitaxel is then extracted from the plant material.
Subsequently, paclitaxel is separated from the paclitaxel extract using a
series of column chromatography separation steps to obtain at least one
fraction containing paclitaxel. The paclitaxel in a fraction that is
obtained from the final chromatography step is crystallized. Using these
methods, high purity paclitaxel may be efficiently obtained from plants
containing paclitaxel.
