The invention discloses a multi-source vegetable outer
vesicle composition as well as a preparation method and application thereof. The multi-source vegetable outer
vesicle composition is prepared from outer vesicles extracted from
spinach leaves, ginger tubers, broccoli buds,
bitter gourd fruits and celery stems. The
spinach leaves, the ginger tubers, the broccoli flower buds, the
bitter gourd fruits and the celery stems are mixed according to the
fresh weight ratio of (3-5): (1-2): (2-3): (1-1.5): (2-4), and low-temperature homogenization,
centrifugation and
ultrafiltration purification are performed to obtain the
spinach-ginger-containing beverage. The particle size of the multisource vegetable outer
vesicle composition is 100-200 nm, and the multisource vegetable outer vesicle composition comprises
transmembrane protein TET8 and membrane anchoring
protein ANNEXIN, and further comprises active ingredients of miR159a, miR166a,
quercetin and
kaempferol. The outer vesicle can target a PPAR gamma / FAS pathway and regulate and control
lipolysis and
metabolism reprogramming of fat cells; meanwhile, an Nrf2 pathway is activated, free radicals are removed,
oxidative stress injury is inhibited, and metabolic diseases such as
obesity,
type II diabetes mellitus and non-
alcoholic fatty liver disease can be effectively improved.
