Application of a UV–vis detection-HPLC method for a rapid determination of lycopene and b-carotene in vegetables
The purpose of this paper is to optimize an HPLC method for the determination of lycopene and b-carotene in vegetables and compare it with a spectrophotometric standard method. Among the different conditions studied the most suitable ones for our samples were: extraction with hexane/acetone/ethanol (50:25:25 v/v/v), evaporation of the hexane layer, dissolution of the dry extract in THF/ACN/meth...

15 صفحه اولPractical method for the detection of tetracyclines in honey by HPLC and derivative UV-Vis spectra.
A technique to detect residual tetracyclines (TCs) in honey by HPLC and derivative UV-Vis spectra is examined in this study. Chromatograms of honey products often experience overlapped peaks and sloping background due to similar retention properties of components or to the presence of impurities. The derivatives provide resolution of overlapped peaks in an UV-Vis spectrum and eventually bring c...
