Characterization of Orange Juice (Citrus sinensis) by Polymethoxylated Flavones

摘要: As a complement to the flavanone glycoside pattern, pattern of polymethoxylated flavones (PMFs) may be very efficient in detecting orange juice (Citrus sinensis) falsifications. The method developed is based on gradient HPLC followed by photodiode array detection after extraction PMFs benzene. Separation done with 15 cm Waters Novapak RP18 column and mobile phase gradient, which increases acetonitrile level presence tetrahydrofuran. C. sinensis authenticity criteria have been proposed for seven main present their average relative peak areas corresponding standard deviations (x±σ) at 340 mn. addition small quantities tangerine Murcott established significant changes PMF
