sternbergia/alkaloid

Alkaloid extracts of four Amaryllidaceae species were studied with respect to their acetylcholinesterase and butyrylcholinesterase inhibitory activity and alkaloid patterns. Twenty-one alkaloids were determined by GC/MS, and seventeen of them identified from their mass spectra and retention times.

Twenty-one alkaloids and related compounds were found in Sternbergia colchiciflora (Amaryllidaceae), a hitherto not studied plant species. Twenty of them were detected by GC-MS in the crude extracts of this plant species. Ten alkaloids were isolated and their structures confirmed by NMR, MS and CD

Lycorine, the most frequent alkaloid found in Amaryllidaceae plants, has been proven to have various biological activities. Therefore, it is important to quantify this compound in Amaryllidacaeae species. In this study, a reversed-phase high-performance liquid chromatographic method has been used

Studies on Alzheimer's disease have been highlighted due to increasing prevalence of this disease. Oldest hypothesis about the pathophysiology strengthens the research of cholinesterase inhibitors for treatment. Amaryllidaceae plants are well known for alkaloids showing cholinesterase inhibiting
