| Abstract: | Six taxanes were isolated and purified from Taxus chinensis cell culture extract using high-speed counter-current chromatography. The crude cell culture extract was first treated with Al2O3 column chromatography and then divided into two parts: fraction 1 and fraction 2. 52 mg of taxuyunnanine C and 11 mg of sinenxane C were yielded from 150 mg of fraction 1. 5 mg of 9-dihydrobaccatin III, 12 mg of baccatin III, 12 mg of paclitaxel, and 17 mg baccatin VI were yielded from 150 mg of fraction 2. The purities of the six compounds were 93.51%, 98.02%, 98.61%, 97.55%, 98.93%, and 98.76%. |
