Extraction of Biomolecules from Spirulina platensis using Non-Conventional Processes and Harmless Solvents

•Extraction and characterization of biomolecules from Spirulina platensis.•Use of different solvents in extraction assisted by microwaves and ultrasound.•Comparison of yield obtained by non-conventional methods with Soxhlet methods.•The extraction time was shorter using microwaves.•The best biomolecule yields were obtained by microwave using water as a solvent.
