Patent number: 11440931Abstract: Provided are a series of crocins compounds and related pharmacological applications thereof in prevention and treatment of Alzheimer's disease. The series of crocins compounds are obtained by taking the Chinese herb, namely Gardenia jasminoides Ellis, as a raw material and separating same by means of various methods. The compounds playing a role in preventing oxidative injury caused by hydrogen peroxide (H2O2) and excitatory amino acid injury caused by L-glutamic acid are screened out by in-vitro cell experiments. The results show that the crocins compounds have good effect in preventing cell injury caused by H2O2 and L-glutamic acid. The compounds have good effect in preventing and treating Alzheimer's disease due to the fact that significant rise of oxidative stress and excitatory amino acid is a key factor for nerve injury in Alzheimer's disease, and have broad development and application prospect.Type: GrantFiled: March 16, 2017Date of Patent: September 13, 2022Assignee: Jinan UniversityInventors: Xinsheng Yao, Yang Yu, Dan Zhang, Yang Ni, Xiuqi Bao, Lin Li, CaixĂa Zang, Hao Gao, Yuanpeng Zheng
