Abstract: An application of N1-dihydrocaffeoyl-N10-caffeoylspermidine in preparation of a drug, health product or functional food is disclosed. It belongs to the technical field of pharmaceutical chemistry. In the dose range of 2-100 mg/kg given to experimental animals, N1-dihydrocaffeoyl-N10-caffeoylspermidine can significantly reduce the number of activities, shorten the sleep latency and prolong the sleep duration of mice with insomnia, and at the same time, it can significantly regulate back the indicator levels of neurotransmitters such as 5-HT, 5-HIAA, GABA and Glu in the brain tissues of mice with insomnia. All of the above confirm that N1-dihydrocaffeoyl-N10-caffeoylspermidine have a sedative hypnotic effect and can be applied for the prevention and treatment of psychiatric disorders such as insomnia, anxiety and depression.
