Abstract
Dye was successfully extracted from red onion (Allium cepa) skin using soxhlet apparatus. The UV-spectral showed that the dye absorbed at 371 nm in dimethylformamide (DMF). The FT-IR indicated the OH-stretching at about 3458 cm-1 and the aromatic C = C vibration at almost 1640cm-1. The GC-MS of the dye gives a complete elucidation of the structure with the parent analyte (M+) occurring at 271; the fragmentation values indicated no significant variation with the calculated values. The dye was tested for microbial activities and found not to be a good environment for bacteria and fungi to inhibit.
