Abstract
To study the composition of wild strawberries grown at high altitude,

total antioxidant capacity, total phenolic compounds, total

flavonoids, and individual phenolic compounds were measured

in wild strawberries (Fragaria vesca) collected between 2,650 and

3,300 m above sea level in Bolivia. Total antioxidant capacity, as

assessed by the ferric-reducing antioxidant power and 2,2¢-azinobis(

3-ethylbenzotiazoline-6-sulphonic acid) methods, was in the

range 16-39 mmol of Trolox equivalents/g fw by both methods. The

total phenolic content was 9.7–21 mmol gallic acid equivalents/g

fw, and the flavonoid content ranged between 2.8 and 4.9 mmol of

catechin... (More)
To study the composition of wild strawberries grown at high altitude,

total antioxidant capacity, total phenolic compounds, total

flavonoids, and individual phenolic compounds were measured

in wild strawberries (Fragaria vesca) collected between 2,650 and

3,300 m above sea level in Bolivia. Total antioxidant capacity, as

assessed by the ferric-reducing antioxidant power and 2,2¢-azinobis(

3-ethylbenzotiazoline-6-sulphonic acid) methods, was in the

range 16-39 mmol of Trolox equivalents/g fw by both methods. The

total phenolic content was 9.7–21 mmol gallic acid equivalents/g

fw, and the flavonoid content ranged between 2.8 and 4.9 mmol of

catechin equivalents/g fw. The data obtained by the four methods

showed several significant linear correlations confirming that flavonoids

and other phenolic compounds contributed significantly

to the total antioxidant capacity values. Reversed-phase high

performance liquid chromatography analysis of extracts subjected

to acid hydrolysis showed the presence of seven major fractions,

tentatively identified as ellagic acid, cyanidin, pelargonidin, quercetin,

kaempferol, gallic acid derivatives, and catechin derivatives.

The data indicated that wild strawberries have a somewhat

higher total antioxidant capacity content in comparison with that

reported for cultivated strawberries. No obvious difference to the composition reported for wild strawberries grown at low altitude

could be found. (Less)
