title: Comparison of extraction techniques for extraction of bioactive molecules from Hypericum perforatum L. plant.
abstract: Three methods commonly used for the extraction of bioactive molecules from natural plant material are compared. Dried Hypericum perforatum L. plant material is subjected to Soxhlet extraction, extraction by ultrasonication, and accelerated solvent extraction. The percentage of two bioactive compounds, hyperforin and hypericin, in the extracts is used as a parameter for comparison of the extraction procedure.
