Chemical composition and neuroprotective activity of hemp seed aqueous extract and their chemotaxonomic significance

Abstract Fructus Cannabis (hemp seed) is important in food and traditional Chinese medicinal applications. Several studies have shown it has antioxidant, antiaging, anti-inflammatory, and neuroprotective properties. Studies have reported its anti-Alzheimer’s disease effects. However, its active substances have not been defined, and little is known about the chemical constituents of the aqueous extract. The chemical profile of the aqueous extract of Fructus Cannabis (EFC) was obtained via isolation, structural identification, and qualitative and quantitative analyses. Twenty-seven compounds were identified, including
