Application of conventional and high-pressure extraction techniques for the isolation of bioactive compounds from the aerial part of hemp (Cannabis sativa L.) assortment Helena

In this work, different extraction techniques (soxhlet extraction, hydrodistillation, subcritical water and supercritical carbon dioxide followed by conventional extraction) were employed for the isolation of bioactive compounds from areal parts industrial hemp (Cannabis sativa L.). The process parameters, time temperature pressure, on yield content examined. As plant material after still contains hydrophilic compounds, was used these. cannabidiol, main cannabinoid present in hemp, extracts between 71.84–163.11 mg/g, while soxhlet extract it much lower (64.40 mg/g). comparison to these significantly cannabidiol detected extracts, ranging 0.0039 0.0183 mg/mL. Comparing all applied techniques, selected as most valuable hemp.
