A fast and simple extraction procedure coupled with a simple HPLC method has been developed in order to determine the arbutin content of leaves of Arctostaphylos uva-ursi plants grown at four different geographical sites and collected during two different seasons. Using the optimised analytical system, the arbutin content of bearberry leaves was found to vary from 6.30 to 9.16% expressed on a dry weight basis. Autumn is shown to be a better period than spring for the collection of plant material in order to obtain the highest yield of arbutin.
