Anti-sugar and anti-oxidation composition as well as preparation method and application thereof

The invention provides an anti-sugar and anti-oxidation composition as well as a preparation method and application thereof, and belongs to the technical field of plant extraction. The anti-sugar and anti-oxidation composition comprises 10-40 parts of vaccinium myrtillus leaves, 5-20 parts of azadirachta indica leaves and 20-60 parts of cymbidium kanran roots, and the multiple bioactive components in the composition are reasonably matched and have a synergistic effect, so that generation of glycosylation end products AGEs can be remarkably inhibited, damage of saccharification to skin is reduced, and generation and repair of collagen are promoted; superoxide free radicals and hydroxyl free radicals are remarkably removed, oxidation reaction is prevented, and cells are protected from oxidative damage; meanwhile, the moisturizing and soothing effects can also be achieved. Moreover, a product (such as anti-sugar and anti-oxidation essence) prepared from the composition is stable in property, free of special smel
