Abstract

Objective: The purpose of this study was to determine whether synthetic red dyes are present in red spinach samples.
Methods: The presence of the dyes Ponceau 4R, Carmoisine, Rhodamine B, Amaranth was determined in red spinach using reactions, followed by
paper chromatography and thin-layer chromatography (TLC)-densitometry. In paper chromatography analyses, analytes were eluted using n-butanol–
ethanol–water (4:5:5) and isobutanol–ethanol–water (3:2:4), and in TLC-densitometry, analytes were eluted with n-butanol–ethanol–water (3:7:1).
Results: No synthetic red dyes were found in the seven red spinach samples.
Conclusion: The synthetic dyes Rhodamin B, amaranth, Ponceau 4R, and Karmoisin were not found as contaminants of red spinach.
