For HPLC analysis, diode array (DAD) and fluorescence (FL) detectors were used. The separation of analyzed compounds was conducted by means of a LiChroCART Purospher C 18e (125 mm × 3 mm, particle size 5 μm) analytical column with LiChroCART LiChrospher C 18 (4 mm × 4 mm, ...
In honey samples of Sinnar-Wad Hashim, Eldewaim, AL-faw areas some Peaks of flavonoids were encountered in small concentration but not detected because of the apparent shortness of their detectors. In a honey sample of Eldamazeen flavonoids were not detected 展开 ...
Characterization of phenolic compounds in strawberry (Fragaria x ananassa) fruits by different HPLC detectors and contribution of individual compounds to t... Phenolic compounds in strawberry (Fragaria x ananassa) fruits were identified and characterized by using the complementary information from different...
The development of automated syntheses with varying complexity was accomplished including HPLC purification, SPE procedures and final formulation with sterile filtration. The six radiopharmaceuticals were obtained in high yield and high specific activity with full automation on the AllinOne synthesis module un...
