Screening the effect of different extraction methods (ultrasound-assisted extraction and solid–liquid extraction) on the recovery of glycoalkaloids from potato peels: Optimisation of the extraction conditions using chemometric tools

•Two methods were optimised for glycoalkaloid extraction from potato peels.•Extraction temperature affected glycoalkaloid in both extraction methods.•α-Solanine found in higher quantity than α-chaconine.•High temperature affected cavitation phenomena in UAE.
