Figure 4From: Validated stability-indicating spectrofluorimetric methods for the determination of ebastine in pharmaceutical preparationsFluorescence spectra of the degradation products of EBS through its reaction with eosin. Where A and B are the excitation and emission spectra respectively of eosin. A' and B' are excitation and emission spectra respectively of: 4a) Alkaline degradation product. 4b) Acidic degradation product. 4c) UV degradation product.Back to article page
