Embodiment 1

[0033] Example 1: Therapeutic Effect of Lactucoside B on Depression in Mice

[0034] 1. Experimental animals: 80 male Kunming mice, weighing 20-22 g, were purchased from the Experimental Animal Center of Zhengzhou University.

[0035] 2. Experimental reagents and instruments:

[0036] Lactucoside B (prepared by Xinxiang Medical College School of Pharmacy, purity greater than 95%), fluoxetine hydrochloride (Eli Lilly Suzhou Pharmaceutical Co., Ltd.), swimming pool, Open·Field open box.

[0037] 3. Experimental grouping and experimental methods:

[0038] Before the experiment, 80 mice were adaptively fed for 1 week with 12 hours of light and 12 hours of no light, and then 10 mice were randomly selected as the normal control group: they were divided into two cages and raised in groups, with 5 mice in each cage. Feed and drinking water were given normally according to the needs, and no stimulation was accepted. The remaining mice were modeled according to the following method. ...

Abstract

The invention provides a new lactuside B purpose, and particularly relates to application in preparation of drugs for prevention and treatment of depressive disorder. The invention has the advantages that lactuside B has significant pharmacological effects which are mainly as follows: the lactuside B can increase body weight of mice subjected to the depressive disorder, increase the number of activities, prolong the swimming time of the mice subjected to the depressive disorder, reduce the immobility time in swimming, enhance sucrose preference degree of the mice subjected to the depressive disorder, and reduce the mortality of the mice subjected to the depressive disorder. The invention provides a new drug for prevention and treatment of the depressive disorder and brings the gospel to patients subjected to the depressive disorder.

Description

technical field [0001] The present invention relates to the new application of Lactucoside B, in particular to the application of Lactucoside B in the preparation of medicaments for preventing and treating depression. Background technique [0002] Pterocypsela elata (Hemsl.) Shih in Act. Also known as high lettuce Lactuca elata Hemsl. , which is a plant of the genus Pteraceae in the family Asteraceae, is distributed in more than a dozen provinces including Jilin, Gansu, and Henan in my country. It has the effects of clearing heat and detoxifying, promoting blood circulation and removing blood stasis, and expelling wind. Lactuside B (lactuside B) is the main extract component of the root of tall lettuce, and its molecular formula is C 21 h 32 o 9 , the general structural formula is as follows: [0003] [0004] Among them, R is preferably Glc or H; R' is preferably CH 2 OH or CHO. [0005] It was early discovered that lettuceside B monomer has anti-cerebral ischemi...
