Abstract: Plant-derived extracellular vesicles (EVs) are membranous vesicles secreted by plants, which include lipid bilayer as the basic framework and encapsulate various proteins, nucleic acid and other active substances. They play an important role in plant growth and development, tissue repair and self-defense. In recent years, extracellular vesicle-like nanoparticles (EVNs) are prepared from plant samples referring to the separation method of EVs and show unique functions. In this review, the above structures are collectively called plant-derived vesicles (PDVs). The biogenesis, separation and characterization methods, in vivo and in vitro properties of PDVs have been reviewed. The biomedical applications of PDVs as natural therapeutic agents and functional drug carriers are described, and finally some opinions on the existing problems and future prospect in this field are put forward.
