Embodiment 1
[0025] Select Rhodiola rosea 375g, Hypericum perforatum 250g, Gastrodia elata 225g, Rehmannia glutinosa 300g, pulverize to 300 mesh, soak in 10L of ethanol with a volume concentration of 75% for 10h, decoct and extract in the dark for 1h (repeated 3 times in total), combine the extracts, Let stand for more than 12h, then filter (or centrifuge), and concentrate the filtrate to a relative density of 2.0. After adding hydrochloric acid to adjust the pH value to 4.0 at 45°C, add a 3% gelatin solution by weight until no precipitation occurs; add distilled water to 1.0g crude drug / ml after centrifugation, and add 0.1% gelatin at 40°C Chitosan colloidal solution, stirred at 50r / min for 5min. Stand still for 12 hours and centrifuge to take the supernatant, add distilled water to 1000ml, and obtain the drug extract. Let it stand for 12 hours, filter, stir evenly, put it into a bottle, and test it for later use.
Embodiment 2
[0027] The medicine extract that adopts embodiment 1 method to obtain is tested.
[0028] 1. Effects of drugs on anxiety behavior in mice
[0029] Male Kunming mice, weighing (20±2) g, were randomly divided into groups after 1 week of adaptive feeding. The diazepam group was intragastrically administered normal saline for the first 3 days, followed by intragastric administration of 5 mg / Kg·d diazepam for the next 4 days; the saline group was intragastrically administered equal-volume normal saline (1ml) for 7 consecutive days; the drug group was administered intragastrically for 7 consecutive days Different doses of the extracts of the medicine of the present invention, wherein the crude drug content of the low dose, middle dose and high dose medicine groups are 5g / Kg·d, 10g / Kg·d, 20g / Kg·d respectively. All animals were housed in separate cages according to groups, free to eat and drink, and began to conduct behavioral tests after 7 days. Immediately after the end of the beh...
Embodiment 3
[0046] The process of this embodiment is the same as that of Example 2. Male Kunming mice with a body weight of (20 ± 2) g were randomly grouped after 1 week of adaptive feeding. Animals were divided into groups: normal saline group, diazepam group, drug group, disassembled recipe 1 group, disassembled recipe 2 group, Rhodiola rosea group and Hypericum perforatum group. The diazepam group was intragastrically administered normal saline for the first 3 days, followed by intragastric administration of 5 mg / Kg·d diazepam for the next 4 days; the saline group was intragastrically administered equal-volume normal saline (1ml) for 7 consecutive days; Each unilateral group was given the corresponding drug extract by intragastric administration for 7 consecutive days. Among them, the crude drug content of the drug group is the drug of the present invention with the optimal dose of 10g / Kg d; the first group of disassembled prescriptions is the drug group lacking the main component Rhod...
