Key words: pine-tree shoots, supercritical fluid extraction, qualitative and quantitative composition, differential thermal analysis, phase and relaxation transitions
Photometric, chromatographic and spectral methods are employed to investigate
qualitative and quantitative composition of extracts from pine-tree shoots obtained by
CO2-fluid extraction. Phase and relaxation transitions and water content in extracts
are studied using differential thermal analysis in the range of 80÷400 K.
