| Popis: | Developing fit-to-purpose analytical screening methods for plant marker constituents by simple and affordable techniques represents a constant and important request from the current transformation chain of plant products. In this work, methods developed on classical thin-layer chromatography (TLC) and overpressured layer chromatography (OPLC) have been applied on some of the most valuable commercial plant products, such as star anise (Illicium verum Hook. f.) essential oil and extracts, common thyme (Thymus vulgaris L.) and sweet fennel (Foeniculum vulgare Mill.) essential oils and acerola fruit (Malpighia punicifolia L.) hydroalcoholic extracts, to evaluate OPLC potentiality in comparison with TLC performances in the detection of some characteristic constituents. OPLC provided higher performance with respect to TLC in all experiments performed due to higher selectivity demonstrated on all the tested marker compounds except for flavonoids in acerola extracts. Considering the usage of planar chromatography in the quality control of plant derivatives, the present paper shows how the OPLC protocols were both highly time- and solvent-saving in comparison with classical TLC. |
