lycopene analysis method

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.

Random-effects models were used to determine the pooled effect sizes. <> 758_6 IN VITRO REGENERATION PLANTS OF TWO CULTIVATED TOMATO LYCOPERSICON ESCULENTUM MILL. Statistical analysis of the pharmacokinetic data using student t test showed a significant increase in AUC 0-t, AUC 0-Inf and t1/2 of paracetamol (P<0.05) and of chlorzoxazone (P<0.05) in the groups pretreated with lycopene (20 mg/kg), significant increase in the volume of distribution of paracetamol (P < 0.05), but no significant difference in that of chlorzoxazone. They occur in tomato fruits and various tomato products in amounts of 2.62−629.00 (lycopene) and 0.23−2.83 mg/100 g (β-carotene). Lycopene content in various tomato products ranged from 42 ppm to 365 ppm. = (A503 x 537 x 8 x 0.55)/(0.10 x 172) = A503 x 137.4 where 537 g/mole is the molecular weight of lycopene, 8 mL is the volume of mixed solvent, 0.55 is the volume ratio of the upper layer to the mixed solvents, 0.10 g is the weight of tomato added, and 172 mM-1 is the extinction coefficient for lycopene in hexane. The in-house validated HPLC method had a limit of quantification of 60 ng lycopene/g product and high precision and accuracy. 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. STANDARDIZATION OF A RAPID SPECTROPHOTOMETRIC METHOD FOR LYCOPENE ANALYSIS. A Lycopene standard (90% all-E-lycopene) and the β-carotene carotenoid C30 reversed-phase column (250×4.6 id, 3 μm) were purchased from Sigma … It is found in red fruits and vegetables such as tomatoes, and known to have strong anti-oxidative effect. Standard methods for determining the carotenoid … Analysis of the Correlation between Lipid Content and Lycopene Content. The method utilizes Supelcosil LC-18 column (150 × 4.6 mm), 3 μm particle size and a mobile phase consisting of acetonitrile, methanol and tetrahydrofuran (70:25:5, % v/v) at a flow rate of 1.0 mL/min. Results have been compared with HPLC chromatography. 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 method provides a method for tank batch fermentation based on biological characteristics of blakeslea trispora.

Enter your International Society for Horticultural Science e-mail or user number. Average daily dietary lycopene intake levels were assessed by administering food frequency questionnaire and were estimated to be 25.2 mg day−1. Therefore the proposed method was used for the routine analysis of the pharmaceutical dosage forms. Efficient assays for detection and quantification o (2002), with some modifications. In this manuscript we describe the method and how it was validated. 758_7 INTEGRATED DISEASE MANAGEMENT IN PROCESSING TOMATO IN TURKEY, 758_8 DEMOGRAPHIC TRAITS OF TWO PHYTOPHAGOUS MITES (TETRANYCHUS CINNABARINUS AND ACULOPS LYCOPERSICI) AND BIOLOGICAL CONTROL ON TOMATO, 758_9 SEASONAL ACTIVITY OF HELICOVERPA ARMIGERA (LEPIDOPTERA: NOCTUIDAE) FOR IMPROVED CONTROL MANAGEMENT STRATEGIES IN PROCESSING TOMATOES, 758_10 INNOVATION IN PROCESSING TOMATO: THE LAB AND THE FIELD, 758_11 USE OF "LOCUST BEAN GUM" IN KETCHUP FORMULATION: RHEOLOGICAL STUDY, 758_12 STANDARDIZATION OF A RAPID SPECTROPHOTOMETRIC METHOD FOR LYCOPENE ANALYSIS, 758_13 THE INSTRUMENTAL MEASUREMENT OF COLOUR AND LYCOPENE IN TOMATO AND TOMATO PRODUCTS, 758_14 EFFECT OF HIGH PRESSURE ON QUALITY PARAMETERS OF CHERRY TOMATO JUICE, 758_15 DYNAMIC DEMAND ANALYSIS FOR TOMATO IN TUNISIA, 758_16 INNOVATION IN TOMATO PROCESSING: OSMODEHYDROFREEZING TO OBTAIN NEW INGREDIENTS FOR OVEN-BAKED PRODUCTS, 758_17 OSMODEHYDROFREEZING OF TOMATO: FROM PRODUCTION TO CONSUMPTION, 758_18 THE NUTRITIONAL AND FUNCTIONAL POTENTIAL OF TOMATO BY-PRODUCTS, 758_19 CAROTENOIDS CONTENT IN RIPE RAW AND PROCESSED (SAUCE) BERRIES OF HIGH PIGMENT TOMATO HYBRIDS, 758_20 INDUSTRIAL QUALITY OF CHERRY TOMATO VARIETIES IN NAVARRE, 758_21 EFFECT OF RIPENING STAGE ON LYCOPENE CONTENT OF DIFFERENT PROCESSING TOMATO CULTIVARS GROWN IN TUNISIA, 758_22 EVALUATION OF TOMATO FRUITS QUALITY AND THE PRODUCTS DERIVED FROM TOMATO PRODUCED AND MARKETED IN ALGERIA BY THE CONTENT MEASURE IN NATURAL ANTIOXIDANTS, 758_23 LYCOPENE INTAKE SIGNIFICANTLY REDUCES BIOMARKERS OF OXIDATIVE STRESS AND BONE RESORPTION IN POSTMENOPAUSAL WOMEN, 758_24 PROCESSING TOMATO CROPPING SYSTEM SUSTAINABILITY PATHWAYS: STATE OF THE ART AND RULES OF THUMB, 758_25 IRRIGATION STRATEGIES IN TOMATO USING LONG TERM WEATHER ANALYSIS, 758_26 TOMATO ROOT'S DISTRIBUTION AND WATER UPTAKE: CONTRIBUTION FOR TRICKLE IRRIGATION MANAGEMENT, 758_27 NITROGEN LEVEL EFFECT ON YIELD AND QUALITY OF FERTIGATED PROCESSING TOMATO IN SOUTHERN ITALY, 758_28 ORGANIC AND MINERAL NITROGEN FERTILIZATION FOR PROCESSING TOMATO IN SOUTHERN ITALY, 758_29 INFLUENCE OF THE FORM OF NITROGEN SUPPLY ON NITROGEN UPTAKE AND ANATOMY STRUCTURES, 758_30 FERTIGATION OF PROCESSING TOMATO IN SIDI BOUZID REGION (TUNISIA), 758_31 MAKE CONSISTENT IRRIGATION WITH TREATED WASTE WATER, WATER SAVING AND HIGH QUALITY FOOD PRODUCTION: THE EU PROJECT SAFIR, 758_32 EFFECT OF POTASSIUM SUPPLY ON THE BEHAVIOUR OF TWO PROCESSING TOMATO CULTIVARS AND ON THE CHANGES OF FRUIT TECHNOLOGICAL CHARACTERISTICS, 758_33 EFFECT OF ETHREL ON RIPENING DYNAMIC AND LYCOPENE CONTENT IN CASE OF TWO PROCESSING VARIETIES, 758_34 AGRONOMIC AND QUALITATIVE EVALUATION OF PROCESSING TOMATO CULTIVARS IN TUNISIA, 758_35 EFFECT OF PARTICLE FILM TECHNOLOGY ON TEMPERATURE, YIELD AND QUALITY OF PROCESSING TOMATO, 758_36 PROCESSING TOMATO MECHANICAL HARVESTING COST EVALUATION, 758_37 AGRIBUSINESS AND CONTRACT FARMING: THE CASE OF TOMATO PRODUCTION IN TURKEY, 758_38 EVALUATION OF SOME TECHNOLOGICAL AND QUALITY CHARACTERISTICS OF TWENTY PROCESSING TOMATO CULTIVARS IN TUNISIA, 758_39 EFFECT OF TECHNICAL NURSERY ON HARVEST CHARACTERISTICS OF PROCESSING TOMATO CULTIVATED IN SIDI-BOUZID REGION (TUNISIA), 758_40 THE INFLUENCE OF PLANTING TIME ON THE LYCOPENE CONTENT OF COMMERCIAL TOMATO VARIETIES FOR INDUSTRY FROM THE EBRO VALLEY, 758_41 CONTRIBUTION OF AN F1 HYBRID IN THE ADAPTATION OF INDUSTRIAL TOMATO TO THE HYDROUS STRESS FROM THE QUALITATIVE AND QUANTITATIVE POINT OF VIEW, 758_42 BEHAVIOUR OF DIFFERENT PROCESSING TOMATO CULTIVARS GROWN ORGANICALLY IN TUNISIA, 758_43 MYCORRHIZAL INOCULATION AND PHOSPHORUS FERTILIZATION EFFECT ON GROWTH AND YIELD OF PROCESSING TOMATO, 758_44 ORGANIC FERTILIZATION ON SOIL WATER CONTENT, YIELD AND QUALITY OF PROCESSING TOMATO, 758_45 COMPARISON OF THE PRODUCTIVITY AND QUALITY OF THE GRAFTED AND UNGRAFTED TOMATO PLANTS GROWN IN THE GREENHOUSE WITH MYCORRHIZA APPLICATION.

Tomatoes and various products derived from thermally processed tomatoes are major sources of lycopene, but apart from this micronutrient, other carotenoids such as β-carotene also are present in the fruit. Ethyl Acetate Extraction Method Lycopene extract from tomato is a lycopene-rich extract prepared from the ripe fruits of tomato (Lycopersicon esculentum L.). 3 0 obj 4. The method comprises eggplant bottle slant culture of mother seeds, 15L-150L-1,500L seed tank amplification culture of seed liquid, and 10m<3> fermentation tank fermentation culture in a mixed ratio of positive bacteria to negative bacteria of 1:10. Extraction of Lycopene and UV- Vis analysis: Approximately 0.6 g of sample was weighed and added to 5 ml of 0.05 % (W/V) BHT in acetone, 5 ml of 95 % ethanol and 10mL of hexane. The outcome of the study shows that the FTIR method is a good analytical method for quantification of lycopene in tomatoes. Obtained crystals were then observed under projection microscope The extracted lycopene in acetone provided three characteristic peaks at 445, 471 and 500 nm. increasing demand for rapid and reliable analytical methods for the analysis and quantification of carotenoids in a variety of matrices.
