十种蜂花粉醇提物对酪氨酸酶的二酚氧化活性抑制作用研究

本实验主要研究了五味子、桃花、蒲公英、山楂、野藿香、山花、黄柏、野玫瑰、黄玫瑰、野菊花十种蜂花粉醇提物对酪氨酸酶二酚氧化活性的抑制作用。结果表明：这十种蜂花粉醇提物对酪氨酸酶均有明显抑制作用，抑制率随着蜂花粉醇提物浓度的提高而提高。其中野玫瑰、黄柏、蒲公英花粉醇提物对两步催化氧化作用都有较好的抑制作用；五味子和野藿香花粉醇提物对酪氨酸酶二酚氧化活性有较好的抑制作用。

Inhibitory Effects of Ethanolic Extracts from Ten Kinds of Bee Pollen on the Activity of Tyrosinase to Oxidize Diphenol

Inhibitory effects of ethanol extracts from ten kinds of bee pollen on the activity of tyrosinase to oxidize diphe-nol were studied,which were schisandra pollen,peach pollen,dandelion pollen,hawthorn pollen, wild ageratum pollen, mixed pollen,amboyna pollen,wild rose pollen,yellow rose pollen,chrysanthemum indicum pollen. The results showed that ethanol extracts from ten kinds of bee pollen had obvious inhibitory activities on tyrosinase oxidation. The higher concentration of ethanol extracts of bee pollen showed the higher inhibition on the activity of tyrosinase. Ethanol extracts of dandelion,amboyna,wild rose pollen had the stronger inhibitory activity of tyrosinase. Ethanol extracts of schisandra, wild ageratum pollen had the stronger inhibitory activity of tyrosinase to oxidize diphenol.
