preparation example Construction

[0038] The present invention also discloses a preparation method of the series of lignan compounds, comprising the following steps:

[0039] Step 1, take the dry stems and branches of Litsea cubeba of the genus Litsea cubeba in the lauraceae family, add 8 times the volume of 70% ethanol to soak overnight, and first use reflux extraction, extract 3 times, each time for 2 hours, and extract the solution while Filtrate hot, combine three filtrates, and then use a rotary evaporator to concentrate under reduced pressure at 50°C to form a viscous liquid, disperse with water, and then sequentially extract with petroleum ether, dichloromethane, ethyl acetate, and n-butanol to obtain petroleum Ether extraction part, dichloromethane extraction part, ethyl acetate extraction part, n-butanol extraction part and water part, and finally concentrate and dry each part;

[0040] Step 2. First, take the dichloromethane extraction part, dissolve it with dichloromethane:methanol at a volume ratio...

Embodiment 1

[0062] Effects of a series of lignans on sleep induced by subthreshold doses of sodium pentobarbital in mice.

[0063] Experimental animals: Kunming strain male mice, SPF grade, weighing 28-32 g, purchased from Hunan Slake Jingda Experimental Animal Co., Ltd., SCXK (Xiang) 2016-0002. The series of lignan compounds adopts the mixture of the above-mentioned 8 compounds of formula I, formula II, formula III, formula IV, formula V, formula VI, formula VII and formula VIII with the same quality.

[0064] Experimental method: After the mice were adaptively fed for one week, the mice were randomly divided into normal group, low (4.5mg / kg), medium (9mg / kg) and high (18mg / kg) dose groups of series lignans 1. Positive drug group was given diazepam solution 2mg / kg by gavage, 15 in every group. The normal group was given equal volume of distilled water by intragastric administration, and the other groups: the administration volume was 0.1ml / 10 g. After a single administration for 30 minu...

Embodiment 2

[0070] Effects of a series of lignans on sleep latency and sleep time in mice induced by suprathreshold doses of pentobarbital sodium.

[0071] Experimental animals are the same as in Example 1. The series of lignan compounds adopts the mixture of the above-mentioned 8 compounds of formula I, formula II, formula III, formula IV, formula V, formula VI, formula VII and formula VIII with the same quality.

[0072] Experimental method: After the mice were adaptively fed for one week, the mice were randomly divided into normal group, low (4.5mg / kg), medium (9mg / kg), high (18mg / kg) dose groups of lignin compounds, positive The drug group was given diazepam solution 2 mg / kg by gavage, 15 rats in each group. The normal group was given equal volume of distilled water by intragastric administration, and the administration volume was 0.1ml / 10g. After 30 minutes of single administration, each mouse was injected intraperitoneally with pentobarbital sodium (45mg / kg) according to the best s...
