Evaluation of the Extraction Efficiency of Biologically Active Compounds from Chamomile Flowers (Chamomilla recutita R.) Grown in the Samara Region by Extractants in the Subcritical State

Resumo

Extracts of biologically active compounds (BACs) from chamomile flowers grown in the Samara region produced by extraction with subcritical water, as well as aqueous ethanol solutions of various concentrations at 150 and 200°C and 5 MPa were investigated using the methods of UV spectroscopy, gas chromatography coupled with mass spectrometry (GC–MS), high-performance liquid chromatography (HPLC), and gravimetry. Identification of BACs in the produced extracts was carried out using reactive gas chromatography.
