Procedimiento

Degradation products were formed in the same proportions as in the experiments conducted under room temperature but in significantly lower quantities. Again, 7-epi-taxol was the main degradation product of paclitaxel. Its amounts formed during 32 h increased from about 3% at pH 7.0 to about 10% at pH 8.0 (see Table 11). Baccatin III and 10-deacethyltaxol were formed for about 5 to 6% at pH 8.0.
