Abstract
The invention discloses an application of roxburgh rose glycoside in preparation of an anti-depression product. Various animal model experiments prove that the roxburgh rose glycoside has an exact curative effect on depression, and the action effect of the roxburgh rose glycoside is equivalent to or better than that of amitriptyline serving as a positive controldrug; as a main chemical component and a natural active substance of a medicinal and edible resource roxburgh rose, the roxburgh rose glycoside has high safety and human body adaptability, has small side effects on a human body, and has creative significance in research and application of anti-depression; experimental research shows that the roxburgh rose glycoside has the potential and prospect of being developed into anti-depression drugs, health care products and healthy food, a foundation is laid for developing the drugs and food for treating depression, and a new way is provided for comprehensive utilization of roxburgh rose fruits, roxburgh rose pomace and roxburgh rose branches, leaves and rhizomes.
Description
technical field [0001] The invention belongs to the field of medicine, and in particular relates to the application of pricklyside in the preparation of antidepressant products. Background technique [0002] Depressive disorder is the disease with the second largest disability rate in the world after cardiovascular disease. It is a complex neurological and psychological disease caused by multiple factors. So far, its pathogenesis has not been fully elucidated. The effective treatment of drugs is still a difficult problem facing the world. Antidepressants commonly used in clinical practice are mainly tricyclics, serotoninreuptake inhibitors and monoamine oxidase (MAO) inhibitors. However, these drugs have long medication cycles, severe adverse reactions, easy relapse after drug withdrawal, and high liver toxicity. Therefore, the study of safe and effective antidepressant drugs is a key development direction in the current research field. [0003] Prickly pear (Rosa roxbur...
