Abstract: Alzheimer's Disease (AD) is a neurological condition that worsens over time and has a gradual start. It has a significant impact on the well-being of human beings. Peptides are substances produced from plants that have been revealed to inhibit the progression of Alzheimer's disease disorders, making them a promising strategy for the prevention of Alzheimer's disease. Nevertheless, because of the enormously convoluted pathophysiology of Alzheimer's Disease (AD) and the recognition that the majority of research on the action of plant-derived peptides is solitary instead of sufficiently comprehensive, the development and implementation of Plant-derived Alzheimer-prevention Peptides (PADPs) have been constrained. The molecular pathways of PADPs, AD-prevention activity, and some perspectives on current advanced technologies have been discussed in this review. Additionally, the review provides a summary of the current techniques available for obtaining PADPs, as well as in vitro and in vivo protocols for evaluating the activity of PADPs in preventing Alzheimer's disease. Additionally, the fundamental concepts for the manufacturing and utilization of PADPs have been developed in this study.
