Key words: chamomile flowers, extraction, subcritical water, 7-methoxycoumarin, luteolin, apigenin, derivatization
UV-spectroscopy, gas chromatography / mass spectrometry, high efficiency liquid chromatography and gravimetry methods were employed to study the extracts of biologically active substances (BAS) from the flowers of chamomile growing in the Samara region. The extracts were obtained using the subcritical water and aqueous solutions of ethanol at 150 and 200 °C and 5 MPa. The BAS in the extracts were identified using a reactive gas chromatography.
