Data expressed as mean ± SD or percentage. TPC: total phenolic contents expressed as g gallic acid equivalents/100 g dry weight; TFC: total flavonoid contents expressed as g catechin equivalents/100 g dry weight; DPPH: 2,2-diphenyl l-picrylhydrazyl. Positive controls: BHT; butylated hydroxytoluene (antioxidant activity), metformin (antiglycation assay), glucobay (α-amylase inhibitory assay), and physostigmine (AChE inhibitory assay).
