Separation and quantitation of orange juices using liquid chromatography of polymethoxylated flavones

A rapid method of extraction and quantitation of polymethoxylated flavones (PMF) using isocratic liquid chromatography is described. With this method the content of six PMF: sinensetin, hexamethoxyflavone, nobiletin, heptamethoxyflavone, tetra-O-methyl scutellarein and tangeretin from 60 commercial orange juices have been determined. The PMF extraction method is mainly established on sample preparations using C$_{18}$ cartridge extractions with water/acetonitrile (60/40, v/v) as mobile phase. PMF compositions of orange commercial juices show a quantitative difference on population samples which are linked to the PMF contents and varieties. By these rapid quantitative method, the PMF values observed were in accordance with literature. This technique present correct characteristics of repeatability and reproducibility (4.5% and 6.6% respectively)
