Embodiment 1
[0015] Embodiment 1: the preparation of xanone compound
[0016] (1) Preparation of extracting liquid: After pulverizing the medicinal material of Yuanbao herb, put it into the extraction tank, heat extraction with 40-90% ethanol for 2-3 times, each time the amount of solvent is about 8-10 times of the amount of crude drug, each extraction time for 1 to 2 hours, and combine the extracts;
[0017] (2) Refining, concentrating and drying: Concentrate the above extract, degrease the concentrate with petroleum ether, extract with ethyl acetate, concentrate under reduced pressure to obtain the ethyl acetate part;
[0018] (3) Separation and purification: dissolve the above-mentioned ethyl acetate part in water, apply macroporous adsorption resin, and elute with water, 20%, 40%, 60% and 80% ethanol system respectively, wherein 80% of the eluting part is used SephadexLH-20 gel column chromatography is purified, and 80% methanol-water is the elution system, obtains 1-hydroxyl-7-methox...
Embodiment 2
[0026] Example 2: Effects of Xanone Compounds on the Immobility Time of Tail Suspension Depression Model Mice
[0027] Mouse tail suspension experiment (Xu Shuyun, Bian Rulian, Chen Xiu. Pharmacological Experimental Methodology, 3rd Edition [M]. Beijing: People's Medical Publishing House, 2002: 807): ICR mice, male and female, 6-8 weeks old , weighing 20±2g, provided by the Experimental Animal Center of the Second Military Medical University of the Chinese People's Liberation Army. Breeding room temperature 18-22 ℃, relative humidity 60%-75%, artificial mixed feed feeding. Randomly divided into: blank control group, positive control group (imipramine 20mg / kg·d), high-dose drug group (60mg / kg·d) and low-dose drug group (15mg / kg·d), 10 small animals in each group Rats were administered continuously for 7 days, and the animals had free access to food and water during the experiment. One hour after the last administration, the tail of the mouse was fixed with a clip about 1 cm f...
