Strawberry is small fleshy fruit, with high values of biochemical contents.
The essential effects of strawberry in human health have been approved due to
significant amount of its vitamin C, antioxidant, phenolic compounds and
anthocyanin. Wild strawberry (Fragaria vesca L.), from Rosaceae family, grows
wildly in some north regions of Iran and have been traditionally used for food and
medicinal purposes. In this study, five wild strawberry populations from Gilan
province in the north of Iran, were used to investigate the value of chemical traits
including; total soluble solid (TSS), titratable acidity (TA), vitamin C and
bioactive content; antioxidant activity, total anthocyanin and total phenolic
content. Among these five populations, Masoleh population showed the highest
value of assessing factors while Ardeh population had the lowest. The total
phenolic content was statistically correlated to the antioxidant activity (r = + 0.99;
p < 0.05) and total anthocyanin content (r = +0.93; p < 0.05). Correlation matrix
of biochemical contents showed that the climate condition (altitude, longitude,
latitude) of collected fruits can be related to the biochemical quantity. According
to the results, high concentration of the antioxidant activity was presented in the
Iranian wild strawberries. Current study suggests that environmental factors can
change the antioxidant capacity and biochemical compositions of wild
strawberry. To sum it up, wild strawberry populations of Iran can be considered
as a good source for breeding program, plus it may be introduced as a fruit with
great value for human health.
