Plants are rich sources of phenolic compounds (flavonoids, tannins and anthocyanins) that are considered as the most important natural antioxidants. Vaccinium arctostaphylos is a shrub that belongs to Ericaceae family and has long been used in Iran traditional medicine due to its effects such as reducing blood glucose and pressure. The main metabolites of V. arctostaphylos are phenols and particularly anthocyanins that have strong antioxidant properties. A comparative study of phenolic, anthocyanin and flavonoid compounds and antioxidant properties of methanol extracts of V. arctostaphylos fruits that are collected from highlands of Talesh (Gilan Province) was done as a replacement for synthetic antioxidants. Prepared extract using acidic methanol and phenolic compounds and antioxidant properties were measured by UV-Vis spectrophotometer. Studying methanol extracts of different regions revealed that the maximum amount of phenolic compounds in extracted powder and anthocyanins and flavonoid in fresh fruits in Chubar region was higher compared to other regions. The results showed this species is a rich source of phenolic compounds and can be used in food and pharmaceutical industry as an antioxidant compounds.
