In this study, the aerial parts and bulbs of nine Allium species were investigated for their functional phytochemical profile, in vitro antioxidant activities, acetylcholinesterase (AChE), butyrylcholinesterase (BChE), α-amylase, α-glucosidase, and tyrosinase inhibitory properties. Phenolics, alkaloids, glucosinolates and other sulfur-containing compounds were distinctively profiled in the different species. Maceration in methanol allowed recovering the highest cumulative phenolic content in A. scabrifolium (42.31 mg/g), followed by A. goekyigiti (33.15 mg/g) and A. atroviolaceum (28.35 mg/g). The aerial parts of all Allium species showed high in vitro antioxidant activity whereas methanolic extract of A. cappadocicum bulb showed the highest inhibition against AChE (2.44 mg galantamine equivalent/g) and the water extracts of A. isauricum aerial part were the best BChE inhibitors (4.31 mg galantamine equivalent/g). Bulbs were the richer source of oligosaccharides, and in vitro digestion determined an increase of oligosaccharides bioaccessibility. A promising nutraceutical potential could be highlighted in our understudied Allium species.

Abstract
In this study, the aerial parts and bulbs of nine Allium species were investigated for their functional phytochemical profile, in vitro antioxidant activities, acetylcholinesterase (AChE), butyrylcholinesterase (BChE), α-amylase, α-glucosidase, and tyrosinase inhibitory properties. Phenolics, alkaloids, glucosinolates and other sulfur-containing compounds were distinctively profiled in the different species. Maceration in methanol allowed recovering the highest cumulative phenolic content in A. scabrifolium (42.31 mg/g), followed by A. goekyigiti (33.15 mg/g) and A. atroviolaceum (28.35 mg/g). The aerial parts of all Allium species showed high in vitro antioxidant activity whereas methanolic extract of A. cappadocicum bulb showed the highest inhibition against AChE (2.44 mg galantamine equivalent/g) and the water extracts of A. isauricum aerial part were the best BChE inhibitors (4.31 mg galantamine equivalent/g). Bulbs were the richer source of oligosaccharides, and in vitro digestion determined an increase of oligosaccharides bioaccessibility. A promising nutraceutical potential could be highlighted in our understudied Allium species.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
