Uva ursi (Arctostaphylos uva ursi (L) Spreng) is a shrubby plant, not very widespread in Albania. It is mainly located on Korabi Mountain.The study of the correlation of the leaves indicators with content of arbutine is an important aspect, in addition to other morphological, biological and chemical studies. The correlations between the leaf indicators with the arbutine are the object of this study because they show the influence that leaf indices have on the content of arbutin, the main component that gives the medicinal values to this plant. From the study carried out, it has a positive correlation with the leaves tail and the normal color of the leaves. Specifically, the leaflet has a coefficient of 0.59, which means that the content of the arbutin depends significantly on the length of the leaves tails. Meanwhile, with the fresh and dry weight of a plant there are also correlations, respectively 0.36 and 0.42, indicating a good influence. As far as the leaf color is concerned, it has a positive relationship only with the normal color, 0.31, which indicates that when the leaf becomes older (dark color), the content of the arbutine decreases.
