optimized for the extraction of paclitaxel (Taxol®) from the needles of yew trees Taxus
baccata L. grown in Iranian habitats. The samples, immersed in a methanol‐water mixture,
were irradiated with microwaves in a closed‐vessel system. The method was evaluated
using a factorial design approach based on parameters such as extraction time,
temperature, methanol concentration in water (v/v), and the ratio of grams of sample to 10 …
