Description
Summary:We compare the effects that different extraction methods based on green chemistry principles have on the degree of extraction of constituents of Scots pine ( Pinus sylvestris ) tree greenery. The gas chromatography–mass spectrometry analyses show that the alcohol extract, the essential oil, and the supercritical extract differ in their qualitative and quantitative compositions. Compared to conventional methods, supercritical fluid extraction with carbon dioxide provides the highest selectivity in the extraction of the diterpenes fraction and an expanded range of constituents extracted from the tree greenery, while preserving the high antimicrobial activity of the prepared extract against the Escherichia coli strains.
