Four types of solvent extraction methods (ultrasound and microwave assisted extraction, pressurized liquid extraction, and extraction in the Soxhlet apparatus) for paclitaxel, cephalomannine, and 10-deacetylbaccatin, taxoids recovered from common yew twigs, were compared. By use of pressurised liquid extraction (PLE), the most effective extractant of taxoids was determined. HPLC was used for the analysis of the extracts. Comparison of the obtained results revealed differences in the extraction power of the applied methods. The greatest yields were obtained by multiple PLE, which can be recommended as the best sample preparation method for taxoids analysis in yew twigs.
