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.
