What is Influence of experimental conditions on the extraction of phenolic compounds from parsley (Petroselinum crispum) flakes using a pressurized liquid extractor about?
The influence of six pressurized liquid extraction parameters (temperature, pressure, particle size, flush volume, static time, and solidto-solvent ratio) on the extraction of phenolic compounds from parsley flakes was examined. Parsley extracts were analyzed for their phenolic content by high performance liquid chromatography and Folin-Ciocalteu assay. The two major phenolic compounds extracted from parsley flakes were identified as apiin and malonyl-apiin. Particle size, solid-to-solvent ratio, and temperature influenced the amount of phenolic compounds extracted from parsley flakes. Higher extraction yields of phenolic compounds were obtained when extractions were performed with the smallest particle size (<0.425 mm) fraction. Temperature also showed a significant impact on the phenolic profile of the parsley extracts. The yield of malonyl-apiin decreased, while the amount of acetyl-apiin improved with the increase in extraction temperature. The latter compound (acetyl-apiin) is formed by decarboxylation of malonyl-apiin. The yield of the phenolic compounds did not increase proportionately with the increase in sample size, thereby suggesting that it is essential to have optimum
