چکیده انگلیسی
Antioxidant activity, determined by DPPH and FRAP assays, was high. The highest activity was found in stem cortex extract from both species with the lowest in R. pentaphylla. A significant correlation between antioxidant activity and phenolic content was revealed. PCAs performed on compound contents or antioxidant activities of all extracts did not reveal clear groupings of populations according to their bioclimatic zone. The global divergence among populations seems to be linked to altitudes and geographic distances. Based on their phenolic contents and antioxidant activity several populations from each species could be used as starting material to develop sustainable production. Conservation strategies of the populations should be made appropriately within their bioclimatic zones in respect to geographic location.
