[0021] A preparation method of mianserin tablets, which comprises the following steps:

[0022] Preparation of ginseng extract: put the ginseng into a pulverizer, smash it through a 50-mesh sieve, then add it to 10 times the weight of water, heat to 70°C, keep it warm for 1 hour, and collect the filtrate; place the filtrate in a vacuum concentrator, vacuum Concentrate to one-third of the volume of the filtrate; add alcohol to make the alcohol content in the concentrate reach 75% (v / v), let stand for 1 hour, filter and collect the filtrate, the filtrate is obtained by rotary evaporation under reduced pressure to remove the ethanol and dry at low temperature. Ginseng extract; the content of saponin compounds is 73.6%;

[0023] Prepare Rehmannia glutinosa extract: take Rehmannia glutinosa, cut into pieces, add 10 times the weight of water to soak for 60 minutes, and then ultrasonically extract for 30 minutes. The intensity of the ultrasonic waves is 25kHz, filtered, and the filtrate i...

[0034] Acute toxicity test: First, dissolve the tablet prepared in Example 1 in physiological saline, stir evenly, and control the concentration at 0.5 mg / mL. Forty Kunming mice, half male and half male, were selected for acute toxicity test. The mice were randomly divided into two groups with 20 mice in each group. The mice were fasted for 12 hours before the experiment and were given the liquid medicine prepared in Example 1 by gavage. The control group was given the same amount of normal saline at 25ml / kg; The drug was administered twice, and the mice were continuously observed for two weeks after the administration, and the toxicity and the number of deaths of the mice were recorded. The experimental results showed that: compared with the control group, there was no significant difference in the mice after the administration. The experiment was observed for two consecutive weeks, and the mice's general condition, diet, drinking water, and weight gain were no obvious abnorma...
