lycopene analysis method

Lycopene (mg/kg fresh wt.) Tomato and tomato-containing products contained the highest amounts of lycopene. Lycopene has been determined in food or biological samples by many analytical methods, such as UV-Visible spectrophotometry, liquid chromatography connected to electro spry-ionization (LC/ESI-MS), reverse phase liquid chromatography (RP-LC), supercritical fluid chromatography(SFC), matrix assisted desorption ionization(MALDI) and especially LC with spectrophotometric detection. Popularity of tomatoes, combined with competition among seed companies, have led to an abundance and often bewildering variety of cultivars intended for … (2007). Carotenoids in tomato were separated and eluted using a reversed‐phase HPLC with a C 30 column and a mobile phase consisting of methyl‐t‐butyl ether, methanol and ethyl acetate. 4 0 obj STANDARDIZATION OF A RAPID SPECTROPHOTOMETRIC METHOD FOR LYCOPENE ANALYSIS. Lycopene content in various tomato products ranged from 42 ppm to 365 ppm. Health professionals and consumers are becoming increasingly aware of the benefits of lycopene consumption; tomatoes provide the greatest source of this important phytonutrient. Our laboratory has developed a standard method for the extraction and determination of lycopene in tomato products. G. Anthon, D.M. The vials were agitated for 5 minutes and left at room temperature to allow phase separation. 758_6 IN VITRO REGENERATION PLANTS OF TWO CULTIVATED TOMATO LYCOPERSICON ESCULENTUM MILL.
