arbutin

This method is a better technique to synthesiz THDB, its inhibitory activity against tyrosinase is better than arbutin or kojic acid, equivalent to phloretin.

本工艺THDB的较佳工艺，THDB对酪氨酸酶的抑制作用比熊果苷和曲酸好，与根皮素相当。

To continue the natural identified chemical after that,we have found that 4-(4-hydroxyphenyl)-2-butanol(Rhododendrol:RD)inhibited the melanin synthesis more than Arbutin did.

我们在探索天化物的过程中,发现4-(4-羟苯基)-2-丁醇(杜鹃醇:以下简称RD)抑制黑色素的作用比熊果苷。
