Embodiment 1

[0025] Embodiment 1. The pharmaceutical composition for the treatment of depression

[0026] A pharmaceutical composition for treating depression, which is composed of 3.5-14g of pachyphyllin and 0.2-3.5g of ginger oil;

Embodiment 2

[0027] The preparation method of embodiment 2 pharmaceutical compositions, its steps are:

[0028] (1) Take the dried Poria cocos sclerotia, extract three times with 10 times the volume of water, combine the extracts, add 95% ethanol after concentration until the ethanol concentration is 80%, and the resulting precipitate is Poria cocos polysaccharide, with a yield of 80.1%;

[0029] (2) Take dried ginger and extract it three times with conventional steam, the yield is 1.0%.

[0030] (3) Take 10 g of Poria cocos polysaccharide and 1 g of ginger oil, add ginger oil with β-cyclodextrin, and mix to obtain the composition PG. An appropriate amount of starch is added to the composition PG to make a tablet.

Embodiment 3

[0031] Example 3 Effect of Composition on Behavior of Desperate Model Mice

[0032] Animal models: mouse forced swimming test and mouse tail suspension swimming test

[0033] Animals: Male Kunming mice, weighing 28±2g, were randomly divided into groups.

[0034] After 15 days of intragastric administration, a behavioral experiment was carried out to measure the absolute immobility time in the forced swimming and tail suspension experiments of mice;

[0035] See Table 1 for the results of the composition components on the mice forced swimming test and tail suspension test. A major symptom of depression is a decrease in motivated behavior, struggling in the forced swim test and tail suspension test is the animal's motivated behavior, and absolute immobility reflects the negative amotivated state of the animal in the experiment. Most antidepressants increase motivated behavior and decrease absolute immobility time in the forced swim test and the tail suspension test. Both high...
