Hemp (Cannabis sativa L.) Seed Phenylpropionamides Composition and Effects on Memory Dysfunction and Biomarkers of Neuroinflammation Induced by Lipopolysaccharide in Mice.

ABSTRACT: Hempseed has achieved a growing popularity in human nutrition, particularly regarding essential amino acids and fatty acids. The multiple positive attributes of hempseed have led to the further study of its constituents. In this study, hempseed extract containing phenylpropionamides (TPA) was obtained and its chemical profile and content were obtained using high-performance liquid chromatography technology based on previous study. The anti-neuroinflammatory effect of TPA extract was evaluated using a lipopolysaccharide (LPS)-induced mouse model. Fourteen phenylpropionamides (TPA) were identified in the obtained extract with a total content of 233.52 ± 2.50 ?g/mg extract. In mice, TPA prevented the learning and spatial memory damage induced by LPS. Increased brain levels of IL-1?, IL-6, and TNF-? in the LPS-induced mice were reduced by TPA treatment. Furthermore, TPA attenuated LPS-induced hippocampal neuronal damage in mice. This study demonstrates the nutraceutical potential of hempseed from a neuroprotective perspective.
