Popis: | Simple method for preparing biologically active material from plant extract may consist of four steps: obtaining an extract from selected plant, analytical chromatography with biological detection and transition to preparative scale, preparative isolation of biologically identified bands/groups of bands from chromatogram, rechromatography of isolated fractions. The next step of proceeding may be a quality analysis of separated material by, e.g., thin-layer chromatography (TLC)-MS Interface or biological studies after isolation. Extracts obtained from four Potentilla species: P. erecta, P. collina, P. megalantha, and P. crantzi were separated on silica plates, developed with the nonaqueous eluent. Immersion—direct bioautography was chosen as a method of detection of bands’ activity for their selection for isolated bands. Antibacterial/bacteriostatic properties of marked areas was the preliminary criterion of choice the samples to the further examinations. Preparative thin layer chromatography allow... |
