ACHE and Alzheimer disease: Therefore, TT-hull extracts (Figure 1) and/or purified compounds (Figure 2) showed AChE inhibitory activities, free radical scavenging activities by ORAC, anti-non-enzymatic protein glycation, and anti-Aβ peptide aggregation in vitro, and they improved the learning and memory functions in scopolamine-induced AD-like amnesiac mice in vivo, which might be beneficial for delaying the onset of AD progression.
