Abstract:

Gas chromatography-mass spectrometry (GC-MS) technology was used to detect chemical compositions and their relative contents of borneol essential oil. By analyzing scavenging activity of 2,2-Diphenyl-1-picrylhydrazyl (DPPH) free radical and 2,2'-azinobis[3-ethylbenzothiazoline-6-sulfonicacid]-diammonium salt (ABTS) free radical, the antioxidant activity of borneol essential oil and trolox were determined in vitro. In order to explore the effect of borneol essential oil on behavior of mice with learning and memory impairment, Morris water maze test and immunohistochemistry experiment were used to judge the cognitive function of mice in normal group, model group, borneol essential oil group and positive group. In addition, after completing the animal behavior experiment, the levels of superoxide dismutase (SOD), glutathione peroxidase (GSH-PX) and malondialdehyde (MDA) of brain tissue were measured. The results show that there are 43 main chemical components in borneol essential oil, such as borneol, d-limonene and 1,8-cineole. Free radical scavenging experiment finds that a certain concentration of borneol essential oil can effectively clean up DPPH and ABTS free radical, but its scavenging ability is less than trolox. The half maximal inhibitory concentration (IC50) of borneol essential oil on DPPH and ABTS free radical are 1.65 and 2.27 g/L, respectively. In Morris water maze, compared to mice in model group, the escape latency and crossing times of mice in borneol essential oil group are improved, and the performance of mice in borneol essential oil group is close to that in positive group. In immunohistochemistry experiment, the immunohistochemical section indicates that compared to mice in model group, the β-amyloid protein of mice in borneol essential oil group decreases, and the situation of mice in borneol essential oil group is close to that in positive group. Compared to mice in model group, the activities of SOD and GSH-PX increase, and the content of MDA decreases in brain tissue of mice in borneol essential oil group. In conclusion, borneol essential oil has certain antioxidant activity in vitro and in vivo, and can improve cognitive impairment in mice.
