Health professionals and consumers are becoming increasingly aware of the benefits of lycopene consumption; tomatoes provide the greatest source of this important phytonutrient. Lycopene content of triplicate tomato fruit samples were determined according to the method of Fish et al. Although spectro- photometry or colorimetry can be used to rapidly assess the lycopene content of products derived from tomatoes, a highly versatile, sensitive and selective method such as HPLC is needed for reliable analysis of food samples. PRINCIPAL COMPONENT ANALYSIS OF SOME PARAMETERS USED FOR LYCOPENE EXTRACTION FROM TOMATOES V. BARBU, C. NEAGU* and M. DRAGAN Food Science and Engineering Faculty, Dunarea de Jos University, 111 Domneasca Street, Galati. … The outcome of the study shows that the FTIR method is a good analytical method for quantification of lycopene in tomatoes. A simple and sensitive isocratic RP-HPLC method with spectrophotometric detection (475 nm) was developed and validated for the determination of lycopene in crude plant extracts. 758_6 IN VITRO REGENERATION PLANTS OF TWO CULTIVATED TOMATO LYCOPERSICON ESCULENTUM MILL. endobj
(Received June 20, 2011; accepted September 15, 2011) The nutritional benefit of tomato-based products has been attributed to their being rich in bioactive compounds such as carotenoids and antioxidant vitamins (vitamins E and C) (1, 2). Lycopene levels in the hexane extracts were calculated according to: Lycopene (mg/kg fresh wt.) Proposed study describes a new and simple RP-HPLC method for the estimation of Lycopene.

The extract is produced by crushing tomatoes into crude tomato juice that is then separated into serum and pulp. Copyright © 2020 International Society for Horticultural Science. The HPLC method of assay provided to the Committee was designed to determine total lycopenes (all-trans-lycopene and cis-lycopene isomers), while total carotenoids are determined spectrophotometrically using a method compatible with that published in the Combined Compendium of Food Additive Specifications (FAO JECFA Monographs 1, vol. The method utilizes Supelcosil LC-18 column (150 × 4.6 mm), 3 μm Skip to main content Enter your International Society for Horticultural Science e-mail or user number. Therefore the proposed method was used for the routine analysis of the pharmaceutical dosage forms. {

Abstract. … The speed of analysis is of particular importance because regulatory compliance monitoring often requires a large number of assays. The subjects were randomly distributed between the two treatment groups: test group (n = 21) 8 mg lycopene/day and placebo group (n = 21) along with adjunctive scaling and root planing.

The correlation analysis was carried out using the Pearson correlation analysis method with a two-tailed test of significance. %����
Obtained crystals were then observed under projection microscope The extracted lycopene in acetone provided three characteristic peaks at 445, 471 and 500 nm. Here, we report a method by which light absorbance measured with a scanning xenon flash colorimeter/ spectrophotometer is used to quantify lycopene content in pureed translucent fruit samples. !2SQY1��L VBɗ���j�K
