Mode opératoire

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 (10% at pH 8.0). Baccatin III and 10-deacethyltaxol were formed for about 5 to 6% at pH 8.0. Found unknown substances were the same.
