The effects of ingredients and ethanol extraction of Scutellaria Radix on the changes of spontaneous alternation in the Y-maze test. NC: normal control group, AC: aging control group, baicalin and baicalen treatment group (200 mg/kg), SBG50 and SBG100 group (Scutellari baicalensis Geroge treatment group, 50 mg/kg and 100 mg/kg). Values are expressed as mean ± standard deviation (mean ± S.D.), and analyzed by one-way ANOVA and multiple comparisons were performed by Tukey HSD test. A criterion of significance was accepted and marked as P < 0.1 (#), 0.01 (##) and 0.001 (*** or ###). The mark of star is AC group versus NC group and the mark of pound is each treatment group versus AC group.
