| Abstract: | Objective： To study the inhibitory effect of the extracts from angelica dahurica on tyrosinase in vitro.Method： The angelica dahurica extracts isolated by macroporous resin were identified by TLC,the content of imperatorin in the extracts was determined by HPLC,and the inhibition rate of angelica dahurica extracts on tyrosinase in vitro was studied by the oxidation rate of L-dopa.Result： The major component of the angelica dahurica extracts was imperatorin.The inhibition rate on tyrosinase were 15.92%±5.3%,25.34%±3.94% and 40.38%±1.45% for different imperatorin concentrations（0.01,0.05 and 0.10 μg·ml-1）.Conclusion： The angelica dahurica extracts show the capability of tyrosinase inhibition. |
