The ethanolic extract of the heartwood of Taxus baccata L. afforded six taxoids, belonging to the skeletally three different groups, 2α, 5α, 10β-triacetoxy-14β-(2-methyl)-butryloxy-4(20), 11-taxadiene (1), taxusin (2), baccatin VI (3), baccatin III (4), 1β-hydroxybaccatin I (5) and taxol (6). The isolation and structure elucidation of three taxoids (3-5) have been presented in this study. This is the first report for the presence of these taxoids in Taxus baccata L. growing in Turkey.
