Taxanes exported from Taxus X media Hicksii cuttings into liquid medium over time

Cuttings from Taxus X media Hicksii were maintained in Gamborg's B5 liquid culture medium, where 10-deacetyl baccatin III, baccatin III, 10-deacetyl taxol, cephalomannine, 7-epi-10-deacetyl taxol and taxol accumulated in the incubation medium over time. Greater amounts of each taxane were recov...

description Cuttings from Taxus X media Hicksii were maintained in Gamborg's B5 liquid culture medium, where 10-deacetyl baccatin III, baccatin III, 10-deacetyl taxol, cephalomannine, 7-epi-10-deacetyl taxol and taxol accumulated in the incubation medium over time. Greater amounts of each taxane were recovered from plant material as compared with liquid medium. Medium was removed and replaced weekly, biweekly or triweekly for up to nine weeks. The sum of all taxol recovered from the liquid that had been harvested from a yew cutting and extracted from the medium weekly over eight weeks was approximately equal to the amount of taxol which would be recovered from the fresh plant cutting, and the cutting still contained taxol. This suggests that in vitro cultures of yew cuttings may be a re-usable source of taxol and related taxanes.
