چکیده
ABSTRACT: The present research presents an analytical methodology based on High Performance Liquid Chromatography (HPLC) and Principal Component Analyses (PCA) for simultaneous quantification differentiation of organic acids sugars in commercial fruit juice samples (orange, grape, apple tangerine). In addition to the development method that generated suitable validation paramters quantitative applications, analysis fourteen use Analysis indicated relationship between constituents very constitutional chemical nature juice. general, grape juices, ascorbic acid was not quantified citric content low; however, concentrations fructose glucose were highest both juices. orange mandarin all analytes, except acorbic acid, did differ statistically from each other. However, these differed significantly others, mainly relation sucrose content. Finally, according malic predominant constituint apple. Results showed chromatographic associated with principal component important information about characteristics potential be used systems quality control identification adulterations.

Determination of total vitamin C in fruit juices and related products by liquid chromatography: interlaboratory study.
A interlaboratory study was conducted to evaluate a liquid chromatographic (LC) procedure for the determination of total vitamin C in foods at levels of 5-60 mg/100 g. Emphasis was placed on fruit juices, although selected foods were also included in the study. Following dissolution of sample in water, endogenous dehydroascorbic acid was converted to ascorbic acid by precolumn reduction with di...
