WebThe HPLC method of assay was developed on the basis of a published method (Schierle et al., 1997) and was designed to determine total lycopenes (as a sum of all detected lycopene isomers) and all-trans-lycopene in the lycopene product. The method includes spectrophotometric Webas reference wavelengths in order to quantify and predict the total amount of lycopene and interferences due to the presence of other carotenoids [18]. HPLC analysis was performed according to method described by Olives and cowork-ers in 2006 [12], with suitable modifications. The chromatographic apparatus consisted
WebHPLC was chosen as an analytical instrument to identify lycopene in local watermelon. Hexane extraction from watermelon juice was used for sample preparation before the sample was run on HPLC analysis. There were two methods of mobile phase was used to detect lycopene in this method. The methods for choosing mobile phase of HPLC were … Webβ-carotene, β-cryptoxanthin, lutein, lycopene) and vitamin C were analysed by high performance liquid chromatography (HPLC) [26,27]. Measurement of ―free‖ and total phenols in the patties was based on the method described by Vinson et al. [28], values being quantified as gallic acid equivalents.
