The effects of YS preparations (1, 3 and 5 μg/L) on memory and locomotor activity in scopolamine (Sco)-treated zebrafish in the Y-maze test. Memory: time spent in each arm (start, other and novel arm); Locomotion: total distance traveled and Turn angle of zebrafish in the tank in the control—untreated group; group treated with scopolamine (Sco 100 µM); groups treated with Sco (100 µM) and (a) YS pur—purified fraction; (b) YS poly—polymeric fraction; (c) YuB—yuccaol B; and (d) GloA—gloriosaol A. Values are means ± S.E.M. (n = 10). For Tukey’s post hoc analyses * p < 0.05, ** p < 0.01, *** p < 0.001, **** p < 0.0001.
