Chemical Composition
The Pacific yew is poisonous because it contains at least 11 alkaloids, known collectively as taxines. The structure of only two of the alkaloid constituents is known: taxine A, which accounts for 30%, and taxine B, which accounts for 2%. Paclitaxel (Figure 128-1) is a pseudoalkaloid but not a constituent of taxine because its nitrogen is acylated with benzoic acid and has no basic principle.[1]
