Rauvotetraphylline E is an indole alkaloid isolated from plants in the Rauvolfia genus, primarily used in biochemical research to investigate the biological activities of plant-derived alkaloids. It shows potential effects on the central nervous system, including modulation of neurotransmitter function and blood pressure regulation. Preliminary studies suggest possible applications in neurological and cardiovascular research, but it is not yet widely used in commercial or clinical settings due to its early-stage investigation.
