|Title:||HPLC QUANTITATION OF MAJOR CAROTENOIDS OF FRESH AND PROCESSED GUAVA, MANGO AND PAPAYA|
|Abstract:||The major carotenoids in 52 samples of guava, mango papaya and some of their processed products were quantitated by HPLC, using both external standardization and standard addition calibration techniques. The results, submitted to the F and t tests, demonstrated that the precision and the means obtained by the two calibration procedures were nor significantly different. The concentrations of beta-carotene and lycopene in guava, beta-carotene in mango and beta-carotene, beta-cryptoxanthin and lycopene in papaya samples were coherent with those obtained previously with open column chromatography. The major problem in the HPLC quantitation of carotenoids is still obtaining and maintaining pure standards. (C) 1995 Academic Press Limited|
