The present invention relates to a plant extract for capturing dicarbonyl compounds, and more particularly, relates to a plant extract of anthocyanins or oligo proanthocyanidin for capturing dicarbonyl compounds. Accordingly, accumulation of advanced glycation end-product (AGE) is reduced inside and outside an organism, in order to effectively prevent cell injury and physiological damage.(not enough words)本發明所揭一種植物萃取物作為捕捉雙羰基化合物之用途,其特別係指由植物中所萃取之花青素(anthocyanins)或是寡原花青素(Oligo Proanthocyanidin)捕捉雙羰基化合物之用途,據此,可減少糖化終產物(Advanced Glycation End-Product,AGE)於生物體內外累積、生成,有效地避免細胞傷害以及生理損傷。
