Effect of lignans from S. chinensis on the level of Glu, γ-aminobutyric acid (GABA), aspartic acid (Asp), glycine (Gly), norepinephrine (NE), 5-hydroxytryptamine (5-HT), taurine, dopamine (DA), acetylcholine (ACh), and acetyl cholinesterase (AChE) in the plasma of rats with AD. The box limits are in the 25th and 75th percentiles; the median is indicated by the horizontal bar; the whiskers are in the 1.5 interquartile ranges; the horizontal boundaries of the boxes represent the interquartile range and the black solid circle is the mean; data not included between the whiskers are plotted as an empty circle. Notes: n = 10, per group; compared with NG by a t-test, ^### P < 0.001; compared with MG, *** P < 0.001, ** P < 0.01.
