Abstract
The objective was to implement green chemistry methodologies in the synthesis of Schiff bases. Natural berry fruit juice freeze-dried extract was employed as natural acid catalyst for the synthesis of N-(4-methoxy benzylidene) aniline from anisaldehyde and aniline, N-salicylideneaniline from salicylaldehyde and aniline, and N-benzylaniline from benzaldehyde and aniline. The Schiff base thus synthesized from natural berry fruit juice freeze-dried extract was characterized by FT-IR and NMR spectral techniques. The antioxidant skin efficacy of these Schiff bases was tested by application on the healthy human skin. The proposed green chemistry methods are convenient, affordable, simple, provide more efficient extraction, and show maximum efficiency.
