一種黃酮衍生物、其製備方法、用途和包含其的美白產品

本发明提供了一种黄酮衍生物、其制备方法、用途和包含其的美白产品。所述黄酮衍生物为具有式I或式II所示结构的化合物。所述黄酮衍生物是通过以黄酮类化合物和苯乙醛类化合物为原料，在酸性环境下，在有机溶剂中反应的方法制备得到。本发明采用苯乙烯基对黄酮类化合物进行修饰，得到的黄酮衍生物能够显著抑制黑色素生成和抗氧化，且效果优于未修饰的黄酮类化合物及市场常用的α‑熊果苷，可用于制备美白用的护肤品、化妆品、药品、保健品或食品等产品。

The invention provides a flavone derivative, a preparation method and application thereof, and a whitening product containing the flavone derivative. The flavone derivative is a compound provided witha structure shown as a formula I or a formula II. The flavone derivative is prepared through the method that flavonoid compounds and phenylacetaldehyde compounds are taken as raw materials, and underthe acid environment, reaction is conducted in an organic solvent. Styryl is adopted to modify the flavonoid compounds, the obtained flavone derivative can significantly inhibit melanin production and resist oxidation, the effect of the flavone derivative is superior than the effect of the unmodified flavonoid compounds and alpha-arbutin commonly used in the market, and the flavone derivative canbe used for preparing products such as whitening skin care products, cosmetics, drugs, health care products or foods.
