Clippings of Taxus X media 'Hicksii' were stored for up to 27 days at 4 degrees and 22 degree to determine the effect of storage conditions on the concentration of taxol and cephalomannine. Although the clippings stored at 22 degrees lost 12.7% more weight than when stored at 4 degrees for 27 days, the yield of neither taxol nor cephalomannine was affected by storage temperature. Taxol concentrations in clippings were 40 and 26% higher in plant material stored at 22 degrees and 4 degrees, respectively, for nine days when compared to concentrations at harvest. There was 35% more cephalomannine after three and nine days of storage than at harvest time. After 27 days of storage, the yield for both taxol and cephalomannine was similar to the yield at harvest. These results indicate that the storage of fresh plant biomass for about nine da s enhances the yield of both taxol and cephalomannine regardless of storage temperature.
