ABSTRACT
To study the antidepressant effect of Shugan Hewei Tang on chronic stress depression model rats, and select the effective substance fractions. Several male SD rats were randomly divided into 17 groups blank control group, model group, positive control group(fluoxetine), Shugan Hewei Tang high and low dose groups, 6 high and low dose groups of different substance fractions. After modeling for 3 weeks and administration for 1 week, the effective substance fractions were selected according to the body mass and behavioral performance of SD rats in each group; several neurotransmitters in hippocampus of rats were determined by LC-MS/MS method, including norepinephrine(NE), serotonin(5-HT), 5-indoleacetic acid(5-HIAA), r-aminobutyric acid(GABA), and glutamic acid(Glu). Behavioral results after modeling showed that as compared with the blank group, the body mass growth of the model group was significantly reduced(P<0.01); the sugar water consumption was reduced(P<0.01); the distance between the open field and the number of crossing the central area were also significantly reduced(P<0.01, P<0.01); the resting time was increased significantly(P<0.01); and the forced swimming time was significantly prolonged(P<0.01), indicating that the depression model was effective. After intragastric administration, as compared with the model group, the above detection indicators of volatile oils, total polysaccharides and terpenoid in Fluoxetine, Shugan Hewei Tang groups were all changed(P<0.05 or P<0.01). The levels of NE, 5-HT and GABA in the hippocampus of the model group were significantly lower than those in the blank group(P<0.01), and the levels of 5-HIAA and Glu were significantly increased(P<0.01). As compared with the model group, neurotransmitters of the treatment groups were changed obviously or significantly(P<0.05 or P<0.01). Shugan Hewei Tang showed obvious anti-depressant effects, and the volatile oils, total polysaccharides and terpenoids acted as the main active substances. The mechanism of anti-depression may be related to its regulation of various neurotransmitter levels in the hippocampus.
