A semi-purified Taxus baccata needles extract was analysed by RP-HPLC. More than 18 taxines and cinnamates were detected by photodiode array detection and LC-MS, 10 of them being positively identified. Furthermore, 10-deacetyl baccatin III (paclitaxe

Geranylgeranyl diphosphate (GGPP) synthase, an enzyme that regulates taxane biosynthesis, was purified to homogeneity from cell cultures of Taxus baccata. The molecular weight of the native protein was estimated to be 769 2 kDa, resulting from the as

The results presented in this paper describe for the first time the presence of an inducible enzyme in the biosynthetic pathway leading to the anticancer drug paclitaxel. Methyl jasmonate, when administered to Taxus baccata cell suspension cultures,

A Taxus baccata cell line has been characterized for growth, nutrient uptake, taxane production and for GGPP synthase activity. The enzyme is extracted by inclusion of non-ionic detergent and its activity parallels taxane production for the first thr

Reversed-phase HPLC was used for the determination of paclitaxel and related compounds in both isocratic and gradient mode, using four different HPLC columns. With the selected acetonitrile–0.05 M ammonium acetate gradient, 13 taxanes of a standard

Solid phase extraction (SPE) methods are studied for the sample pretreatment for HPLC analysis ofTaxus cell suspension cultures. Various types of SPE materials were tested for the extraction of both the taxane standards and samples of various origin.
