Abstract: An antitumor compound of formula (5) ##STR1## and also provided by the present invention is a method of preparing a compound of formula (5) whereby diesterification of the alcohol groups located at the 2' and 7 positions of paclitaxel is followed by the hydrolysis of the 2' hexanoate group resulting in 7-hexanoyltaxol.

Abstract: In general the present invention relates to a process for the removal of undesireable compounds or residues from an extract which are more polar or less polar than the desired target compound. The preferred embodiment of the present invention is a three step process and is described in detail below. The first step includes contacting a plant material that contains the desired target compound(s) with a solvent, thus producing a crude extract containing a mixture of compounds that includes, in addition to the undesireable residues, the desired target compound(s). The second step involves passing the crude extract through a series of columns containing an absorbent that retards the movement of the undesireable compounds, while allowing the desired compounds to pass. The third and final step involves drying the eluant product to achieve a final product.
