Abstract

The average annual taxol content of shoots with dark green needles from Irish Yew (Taxus baccata var. fastigiata) was found to be 0.0075%. Maximum levels were recorded in April (0.010%) and minimum in February. Golden-leaved (“aurea”) varieties contained only traces of taxol. Shoot growth took place mainly between May and July.
