曾报道,苹果中的多酚(AP)具有抗氧化、抗过敏等作用。以儿茶素或表儿茶素为构成单位的原花色素类约占50%,因构成单位数与结合模式不同而存在多种异构体。研究表明,AP具有抑制黑素生成的作用。本次探讨了AP中的原花色素组分以根据聚合度分离的组分对黑素生成的抑制作用。方法:① It has been reported that polyphenols (AP) in apples have antioxidant and antiallergic effects. About 50% of proanthocyanidins are composed of catechins or epicatechins, and there are multiple isomers due to the difference in the number of constituent units and the binding modes. Studies have shown that AP has the effect of inhibiting melanogenesis. This time, we examined the inhibitory effect of components of proanthocyanidins in AP on the melanin production by components separated according to the degree of polymerization. Method: 1
