Název v původním jazyce

Microwave Assisted Extraction and Solid Phase Purification Procedures Prior to the Chromatographic Determination of Phenolic Compounds in Plant Materials.

Popis výsledku v původním jazyce

A fast, sensitive and selective procedure employing a combination of microwave-assisted extraction (MAE) and solid phase extraction (SPE) was applied prior to liquid chromatographic identification and quantification of phenolic compounds in plant materials. Microwave assisted extraction (MAE) has been tested and optimized for the isolation of phenolic acids (gallic, protocatechuic, p-hydroxybenzoic, chlorogenic, vanilic, caffeic, syringic, p-coumaric, ferulic, sinapic, benzoic, m-coumaric, o-coumaric, rosmarinic, cinnamic acids) and 3,4-dihydroxybenzaldehyde, syringaldehyde, p-hydroxybenzaldehyde, vanillin in various plants. The effects of experimental conditions on MAE efficiency, such as solvent composition, temperature, extraction time, have been studied. The extraction efficiencies were compared with those obtained by computer controlled two steps Soxhlet extractions. Plant extracts were purified and phenolic compounds were pre-concentrated using solid-phase extraction (SPE) on pol
