Embodiment 1

[0018] The preparation of the petroleum ether extract (hereinafter referred to as the Ginseng variable leaf extract) after the ethanol extraction of the ginseng of embodiment 1

[0019] Take 5kg of ginseng stems, crush them, add purified water (liquid-solid ratio: 3mL:1g), heat to boiling, keep for 5 hours, filter, concentrate the filtrate to 1 / 3 of the original volume, cool to room temperature, and At 18-23°C, slowly add 95% mass concentration of ethanol while stirring to extract twice, each extraction for 14 hours (the amount of ethanol is twice the volume of the filtrate after concentration), and then use 70%-75% mass concentration of ethanol (The amount of ethanol is twice the volume of the filtrate after concentration) extract 3 times, extract 14 hours each time, and combine the extracts; heat the extracts until all the ethanol is volatilized (no alcohol smell), add an equal volume of petroleum ether, and stir at room temperature Soak for 5 hours, then separate the upper ...

Embodiment 2

[0020] Embodiment 2 antidepressant animal simulation drug efficacy experiment

[0021] The animal antidepressant efficacy experiment was carried out with the petroleum ether extract of Ginseng variable leaves extracted with ethanol.

[0022] 1. Forced Swimming Pre-Experiment in Mice

[0023] The mice were randomly divided into 3 subgroups, namely the model group (solvent group, only experiment without administration), the fluoxetine hydrochloride group (0.02g / kg), and the high-dose group (8g / kg) treated with Ginseng variable leaf extract. kg), 3 in each group. Pre-swim for 15 minutes before the experiment, and perform the formal forced swimming pre-test 24 hours later, that is, after 30 minutes of intragastric administration of mice, place them in a 2000ml large beaker with a height of 20cm and a diameter of 14cm. The water height of the beaker is about 10cm, the water temperature is 23 ± 2 ℃, the test mice are forced to swim for 6 minutes, and the cumulative time of the mic...

Abstract

An application of the extract of ginseng variegata in the preparation of antidepressants. The extract of ginseng varifolia is taken from the stalks of ginseng variegata and crushed, soaked in pure water and heated, and the obtained leaching solution is sequentially washed with 95% ethanol, 75% After ethanol extraction, and then petroleum ether extraction, the extract was concentrated and dried to obtain. The forced swimming test and the tail suspension test of mice show that the extract of the ginseng has a significant antidepressant effect and has a good effect on treating depression. The long-term mouse toxicity test shows no abnormality and good safety, and it is expected to be developed as a new antidepressant natural medicine.

Description
