Development and Validation of an HPLC-UV Method for Arbutin Determination in Bearberry Leaves

An HPLC-UV method for arbutin determination in bearberry leaves was developed. The conditions were selected. The main metrological characteristics were evaluated. The developed method was shown to be highly efficient and promising and could be recommended for arbutin determination in bearberry leaves as an alternative to the existing pharmacopoeial titration method.
